<strong>Steca</strong>‘s Charging Technology<br />
The performance of our products is shown by the accuracy of<br />
the state of charge (SOC) measurement, which results in the<br />
long lifetime of the battery.<br />
What does SOC mean<br />
The SOC (State of Charge) indicates<br />
the actual charging status of the battery.<br />
If the battery is fully charged the<br />
SOC is 100 % - if it is completely empty<br />
the SOC is 0 %. All values in between<br />
are possible, but a lot of battery types<br />
should not reach SOC values less than<br />
30 %. It is important not to confuse<br />
the SOC with the capacity of the battery.<br />
The SOC does not reflect the remaining<br />
capacity of the battery. The actual<br />
remaining capacity of the battery is<br />
influenced by a lot of parameters besides<br />
the SOC. Multiplying the SOC with<br />
the nominal capacity of the battery<br />
results in information about the residual<br />
capacity of the battery. This value<br />
does still not reflect the remaining capacity<br />
accurately due to various other<br />
parameters including the age of the<br />
battery.<br />
Why is SOC calculation important<br />
If a battery is charged, the charge controller<br />
needs to know if it is full to prevent<br />
a batteries damage due to over<br />
charging. While discharging, the controller<br />
needs to know if the battery is<br />
empty in order to prevent dangerous<br />
deep discharging. There are several<br />
possibilities to determine if the battery<br />
is full or empty. The most common<br />
criterion is the voltage of the battery.<br />
A certain fixed voltage is set to disconnect<br />
the load and protect the battery.<br />
Unfortunately this criterion is improper.<br />
Especially in solar systems, low<br />
discharging currents are common and<br />
lead to improper battery maintenance<br />
if a fixed voltage for load disconnection<br />
is used. Better solutions also take<br />
the charging / discharging current into<br />
account to determine if the battery<br />
has to be disconnected from the load.<br />
But also this method does not allow<br />
an adequate load disconnection to<br />
protect the battery optimally due to<br />
a very low accuracy and a high error<br />
rate. A lot of additional parameters,<br />
like temperature, the age of the battery,<br />
the user behaviour and other values,<br />
influence the battery.<br />
Only an accurately calculated state of<br />
charge allows to disconnect the load<br />
correct according to the properties of<br />
the battery. This is why <strong>Steca</strong> developed<br />
a powerful and precise algorithm<br />
to determine the actual state of charge<br />
of a battery.<br />

How does the <strong>Steca</strong> SOC<br />
algorithm work<br />
The <strong>Steca</strong> state of charge algorithm is<br />
a combination of different methods<br />
in order to ensure a precise calculation<br />
combined with a stable long time<br />
performance. Cost optimised product<br />
realisation is additionally another important<br />
point for <strong>Steca</strong>. Years of experience<br />
in this field and important research<br />
activities led to a self learning<br />
„fuzzy logic“ algorithm. It takes into<br />
account the user behaviour and the<br />
ageing of the battery. The voltage of<br />
the battery, as well as all battery currents,<br />
are watched closely by the charge<br />
controller in combination with the<br />
temperature. The charger approximates<br />
the SOC, during a learning period<br />
which takes place in the first cycles.<br />
By monitoring the battery and adapting<br />
parameters to the changes, a self<br />
learning algorithm results that is also<br />
able to take the use of the battery into<br />
account. This characteristic makes the<br />
<strong>Steca</strong> SOC algorithm a powerful and<br />
reliable function, which will ensure<br />
the correct monitoring of the battery.<br />
The user benefits from a fast and<br />
precise information about the battery<br />
status that is displayed on the charge<br />
controller. Finally the user benefits<br />
from the most important advantage<br />
to enlarge the life-time of the battery<br />
with the help of an optimised battery<br />
maintenance.<br />
Which chargers from <strong>Steca</strong><br />
carry the optimised algorithm<br />
The <strong>Steca</strong> product range is divided into<br />
two lines. One is optimised for use in<br />
simple applications with less demand<br />
and equipped with the minimum necessary<br />
features. The other line is designed<br />
to cover high-end demand to<br />
supply a good communication interface<br />
to the user and optimised battery<br />
maintenance features. For both lines<br />
there exist charge controllers in a wide<br />
power range. Charge controllers in a<br />
wide power range exist for both lines.<br />
All chargers that are equipped with<br />
the special <strong>Steca</strong> State of Charge algorithm<br />
are marked with the SOC symbol<br />
in this catalogue.<br />
Example<br />
The graph shows the properties of a 28 Ah lead acid battery in relation to<br />
the charging / discharging current, the voltage and the state of charge. If the<br />
full battery is discharged with 50 A and a load cut off voltage of 1.85 V/cell<br />
is applied (equal to 11.1 V for 12 V battery) the load will be disconnected at<br />
around 70 % state of charge. This means the battery is still quite full but the<br />
load can no longer be supplied due to deep discharging protection. If it is discharged<br />
with 5 A, the voltage of 11.1 V will lead to a disconnection at 10 %<br />
state of charge which is already a dangerous deep discharge for the battery.<br />
With the <strong>Steca</strong> SOC algorithm the load will be disconnected along the line<br />
of 30 % SOC in dependence of the discharging current at the cross with the<br />
discharging current line. Only this complicated procedure can ensure optimal<br />
battery maintenance.<br />

System overview<br />
A Solar Home System consists of a <strong>Steca</strong> Solar charge controller, a battery, a solar<br />
module and the load. The load is always a DC load in standard Solar Home Systems.<br />
The charge controller is connected directly to the battery. The module and the load<br />
are connected directly to the charge controller terminals. <strong>Steca</strong> controllers regulate<br />
the complete energy flow within the system. The battery is charged by the current<br />
from the solar module. If the battery is full, the charge controller limits the current<br />
to the battery to protect the battery from over charging. If the load discharges the<br />
battery, the controller also cuts off the load before the battery is empty, in order<br />
to prevent a dangerous deep discharge of the battery. <strong>Steca</strong> controllers also have<br />
an integrated intelligent battery monitoring system. The optimal charging strategy<br />
will be chosen depending on the need of the battery. In Solar Home Systems the<br />
charge controller is the central device – all functions of the system are influenced<br />
by this controller. Due to this fact it is important to choose a good controller.<br />

System overview<br />
Stand alone inverter systems consist of a standard Solar Home System with solar<br />
module, battery and solar charge controller, plus an additional inverter that supplies<br />
AC power. To such a system you can connect any commercial AC appliance<br />
known from the public grid. Furthermore, it is even possible to run DC loads. The<br />
inverter is connected directly to the battery with a short and thick cable. Such a<br />
system can be realised as a standard 12 V system, alternatively also as a 24 V or<br />
48 V system for higher power demands. Due to the simple system concept, the<br />
installation is fast and easy to do.<br />

System overview<br />
The main feature of a hybrid system is the use of two or more different energy<br />
sources. For so-called photovoltaic hybrid systems in the field of solar energy especially<br />
a diesel generator, a wind generator or a public grid is used as an additional<br />
source of energy. The inverters with integrated battery charger designed for hybrid<br />
systems supply the connected alternating current loads either out of the battery<br />
or from the second energy source – always according to the requirements of the<br />
system. It is also possible to recharge the battery from the additional energy source<br />
via the battery charger. The advantage of photovoltaic hybrid systems is that the<br />
solar generator does not have to be oversized to supply the loads even during<br />
months with low solar irradiation. This saves a significant amount of the initial<br />
investment. The solar produced power is always used primarily in the system. But<br />
in combination with the second energy source reliable AC power is available day<br />
and night throughout the year.<br />

Different Hybrid System Concepts<br />
Single Phase System Concept<br />
The <strong>Steca</strong> solar charge controllers<br />
Tarom or Power Tarom are the central<br />
and intelligent devices within the system,<br />
which regulate the energy flow<br />
and are responsible for battery supervision.<br />
The Tarom / Power Tarom<br />
will be connected directly to the battery.<br />
The DC-bus is also connected directly<br />
to the battery, while the <strong>Steca</strong><br />
PA HS200 is located in the minus of<br />
the battery connection to submit all<br />
data to the Tarom / Power Tarom. All<br />
other components, chargers, inverters,<br />
or any other devices like remote switch<br />
<strong>Steca</strong> PA 15, are connected to the<br />
DC-bus. If the SOC of the battery is low,<br />
the output of the PA 15 is connected<br />
to a relay to effect an automatic start<br />
up of a diesel generator. The working<br />
contact of the relay built the dry contact<br />
connection to the diesel start up<br />
switch.<br />
The Tarom / Power Tarom manages<br />
the DC hybrid system. The current<br />
sensor PA HS200 submits all charging<br />
and discharging information coming<br />
from the DC-bus to the Tarom / Power<br />
Tarom. With the help of this information<br />
the controller is able to calculate the<br />
actual SOC of the battery, which is<br />
submitted to all <strong>Steca</strong> PA 15 switches<br />
by DC power-line modulation. Each<br />
PA 15 can be configured to switch on<br />
within a specific SOC range. If the inverter<br />
discharges the battery the PA<br />
HS200 submits this information to the<br />
Tarom / Power Tarom which calculates<br />
the SOC. The PA 15 that is connected<br />
to the inverter / charger follows this information.<br />
As soon as the SOC drops<br />
down below a certain value, it switches<br />
on the diesel generator. The generator<br />
now supplies the load and charges the<br />
battery at the same time. As soon as<br />
the SOC reaches the upper value configured<br />
at the PA 15, the diesel will be<br />
switched off by the PA 15 again.<br />
To realise an automatic AC energy management<br />
the AC output of the diesel is<br />
connected to the AC input of the inverter,<br />
while the load is always connected<br />
to the inverter output. In the case of<br />
diesel AC availability, the inverter automatically<br />
switches to transfer mode to<br />
supply the load and to charge the battery<br />
at the same time. If diesel AC drops<br />
down an automatic switch to battery<br />
mode is carried out by the inverter.<br />
Important features<br />
• Combination of different power<br />
sources like PV, wind, diesel generators<br />
etc.<br />
• 24 h / d full 230 V~ power supply<br />
• 12 V / 24 V or 48 V overall DC-bus<br />
• Automatic energy management<br />
regulation based on the State of<br />
Charge of the battery. Including<br />
automatic start of controllable<br />
power sources like e. g. diesel<br />
generators<br />
• Optimised battery charging algorithm<br />
Three Phase System Concept<br />
The regulation concept is similar to<br />
the single phase concept. If more than<br />
one Tarom / Power Tarom is used, one<br />
of them has to be defined as the master<br />
Tarom; all others are automatically<br />
slave Taroms. The master Tarom /<br />
Power Tarom is connected directly to<br />
the battery while all slaves are connected<br />
to the DC-bus. Only the master<br />
Tarom / PowerTarom displays the correct<br />
SOC of the battery and controls<br />
the overall energy flow within the<br />
system. Slave Taroms / Power Taroms<br />
only supervise the charging of the modules<br />
to which they are connected.<br />
To realise a three phase power supply<br />
system, three inverters are connected<br />
to the DC-bus. Therefore special three<br />
phase options are needed for the inverters.<br />
In addition to the three phase<br />
system, a single phase inverter / charger<br />
can be connected to the DC-bus<br />
to recharge the battery from any AC<br />
power source.<br />
Both three phase and single phase hybrid<br />
systems are based on the same<br />
energy management. With the help of<br />
the <strong>Steca</strong> PA HS200 current sensor, the<br />
master Tarom / Power Tarom is supplied<br />
with the charging and discharging<br />
currents of the components like<br />
slave Taroms / Power Taroms, inverters<br />
and others. The <strong>Steca</strong> PA 15 switches<br />
the generator on and off according to<br />
the calculated SOC. The three phase<br />
inverters are equipped with an integrated<br />
low voltage disconnection.<br />

General Recommendations<br />
for Inverter and Hybrid Systems<br />
Sine Wave Inverters<br />
In contrast to modified sine wave inverters,<br />
the <strong>Steca</strong> sine wave inverters<br />
supply a pure and accurate regulated<br />
sine wave to the load. Only this pure<br />
sine wave technology allows the user<br />
to run all types of AC loads within the<br />
off-grid photovoltaic system, which<br />
can normally be used in grid connected<br />
mains power supply systems.<br />
Additionally, this technology guarantees<br />
a noiseless operation, which is<br />
especially important if critical applications<br />
like radios, television and other<br />
sensitive devices are used.<br />

Inverter selection<br />
Sine Wave<br />
The inverter should be sized properly<br />
depending on the type of application.<br />
The summary of comsumption should<br />
be covered by the continuous power<br />
of the inverter while starting currents<br />
should be within the max. power.<br />
To allow an future increase of consumption<br />
<strong>Steca</strong> recommends to oversize<br />
the inverter.<br />
PV generator and charge<br />
controller selection<br />
The solar module array has to be adapted<br />
to the local solar irradiation conditions<br />
and the energy consumption of<br />
the system. To avoid downtimes, the<br />
PV generator must provide enough<br />
energy even during months with low<br />
irradiance to meet the needs of the<br />
loads.<br />
The minimum size of the regulator had<br />
to cover the max. short circuit current<br />
of the module and the max. load current.<br />
Sommetimes even technical feature<br />
had to be supported in the application<br />
and a high end regulator should<br />
be used in a low power system.<br />
To keep the initial cost on a low level<br />
we recommend to size modules and<br />
battery according to the actuel consumption<br />
and to size the controller<br />
corresponding to future re-fitting.<br />
Battery rating<br />
The battery has to be sized properly<br />
in order to enable the inverter also to<br />
supply high demanding loads. Some<br />
critical loads like fridges, freezers,<br />
pumps and motors draw extremely<br />
high currents during a short starting<br />
phase. To run such loads it is important<br />
to use a capable inverter with an extremely<br />
high overload capacity especially<br />
during the starting phase. The battery<br />
also has to be sized in a proper way to<br />
be able to supply enough current if requested<br />
by the inverter. The following<br />
formula recommends how to size the<br />
battery: the batteries capacity should<br />
be at least 5 times more than the nominal<br />
power of the inverter divided by<br />
the nominal voltage of the battery<br />
C_batt ≥ 5 h * Pnom / Unom<br />
while Pnom indicates the nominal power<br />
of the inverter in Watt and Unom<br />
the nominal voltage of the battery in<br />

Examples for battery selection<br />
Selection of system voltage<br />
The system voltage of the off-grid photovoltaic<br />
system should be selected<br />
in dependence of the load demand.<br />
The higher the load demand the higher<br />
the system voltage. If no 12 V DC<br />
loads are connected, a higher system<br />
voltage of 24 V or 48 V should be preferred<br />
to reduce the DC-current in the<br />
system. Above around 2500 W, only<br />
inverter power 48 V systems can be recommended.<br />
The higher the voltage,<br />
the lower the system currents. Finally,<br />
lower currents result in higher system<br />
efficiency due to less losses.<br />
Selection of cables<br />
DC currents are typically high in inverter<br />
systems. Due this fact, it is essential<br />
to use proper cables between the<br />
inverter and the battery. Always connect<br />
the inverter directly to the battery.<br />
Choose a DC inverter cable that is<br />
as short as possible. In addition, the<br />
thickness of the cable should be sized<br />
properly. Choose a thicker cable in<br />
case of doubt – this can have a significant<br />
influence to the overall system<br />
behaviour. By using thick and short<br />
cables the system losses can be reduced<br />
– the result is higher efficiency and<br />
better performance. If the inverter comes<br />
with a DC cable never enlarge this<br />
cable or use a thinner one.<br />

solar home systems with either a 3 or 5 Amp solar charging and<br />
load current capacity (up to 75 Wp). Loads such as lights, radios or<br />
small TVs can be switched „off“ manually on the controller without<br />
additional wall mounted switches. In professional applications such<br />
as telecommunication, the controller can also be used in small photovoltaic<br />
power supply systems. Thanks to the universal series switching<br />
technology the controller can be used with amorphous, thin<br />
film and crystalline solar modules.<br />

The <strong>Steca</strong> Tarom is the high end solar charge controller optimally<br />
designed for demanding telecom applications and complex off-grid<br />
PV hybrid system architectures. A huge variety of exiting features<br />
allows the user to adapt this controller to the special needs of the<br />
specific installation.<br />
The optimised SOC calculation of <strong>Steca</strong> is implemented in the<br />
Tarom. It is your best choice for the medium and large power range<br />
(up to 2400 Wp) on three voltage levels (12 V, 24 V, 48 V). Additionally<br />
it is possible to connect further devices like a temperature<br />
sensor, a datalogger and a remote switch to configure and monitor<br />
the photovoltaic system optimally. An in built Ah counter gives additional<br />
valuable energy balance information to the user.<br />

Shunt<br />
All currents which run through the Tarom and Power Tarom charge<br />
controllers are measured for an accurate calculation of the battery’s<br />
state of charge. However there are currents which the charge controllers<br />
do not measure like inverters which are connected directly<br />
to the battery or back up generators which feed their energy directly<br />
into the battery. The PA HS200 shunt measures these currents<br />
through the “hall” effect and transmits them digitally to the Tarom<br />
controllers.<br />

<strong>Steca</strong> PA 1<br />
Remote Control<br />
Tarom and Power Tarom charge controllers send out signals<br />
(125 kHz on 300 baud) which are modulated on the DC power line<br />
and received by <strong>Steca</strong> PA 15 remote control. These signals are information<br />
on the state of charge (SOC) of the battery. No additional<br />
cabling is required. The PA 15 has five different operation modes<br />

Solar Charging Station<br />
The PL 2085 is a solar charging station which charges up to 8 leadacid<br />
batteries simultanously. The microprocessor controlled charging<br />
station recognizes the connection sequence of the batteries. The<br />
battery which is connected first is charged first and as soon as the<br />
first battery is full, it switches over to the second battery etc.<br />
Every battery terminal of maximum 5 Amps is a seperate DC / DC<br />
converter with maximum power point tracking (MPP) of the solar<br />
generator. Up to two battery terminals can be connected in parallel<br />
on the same battery. These terminals are protected against wrong<br />
polarity, short circuit, no load operation and overload. Batteries are<br />
charged to predefined IU constant current charging procedures until<br />
end of charge voltage is reached. Battery charging starts even<br />
from run down batteries at voltages higher than 5V. At night the<br />
charging station works in a energy saving mode and no battery data<br />
is lost.<br />

MDC / MDCI<br />
DC-DC Voltage Converter<br />
These high end DC-DC converters can be used if the DC output<br />
voltage of a photovoltaic system does not fit to the needs of the<br />
load. Since most low-voltage equipment, such as lights, multimedia<br />
equipment, radio communication equipment or mobile telephones,<br />
are designed for 12 V, the different converter types deliver a stable<br />
12 V supply. If for example a 12 V DC energy saving lamp is used in<br />
a 24 V or a 48 V system a suitable DC-DC converter must be connected<br />
in between the load output of the charge controller and the<br />
12 V energy saving lamp.<br />
The MDC and MDCI converters are optimally designed for the use in<br />
photovoltaic applications. The types with 13.6 V output voltage can<br />
also be used as a battery charger for a 12 V~cessory battery in an<br />
otherwise 24 V system.<br />
For security reasons the MDCI series is electrically isolated in order<br />
to protect the load. But even the converters of the MDC series can<br />
withstand high voltage spikes at the input (load dump) and therefore<br />
protect your appliances at the output against damaging overvoltage.<br />
Features<br />
• Great variety of different input<br />
voltages<br />
• Output for 12 V or 24 V loads<br />
• Maximum power 360 W<br />
• Efficiency of up to 90 %<br />

A particular feature of the AJ inverter series is its wide range of<br />
available power classes and DC input voltages, enabling the optimal<br />
inverter to be used for any application. The cables for the<br />
battery and load connection are already pre-mounted on the AJ,<br />
thus making it easier to connect the device. The automatic standby<br />
mode considerably reduces the inverter’s self consumption. The AJ<br />
inverter’s excellent overload capacity ensures that even critical loads<br />
can be operated easily.<br />

The <strong>Steca</strong> XPC series of inverters feature a very high overload capacity<br />
that even enables them to operate highly critical loads. Other<br />
important features of these high-quality inverters are their powerful<br />
device protection and their individual low self consumption. The XP-<br />
Cs combine a sine wave inverter, 4-stage battery charger and transfer<br />
system in one device, therefore making them particularly suitable<br />
for hybrid systems. The in-built multifunctional contact enables<br />
you, for example, to switch on and off diversion loads for excess<br />
power or start a diesel generator to recharge batteries.<br />

The <strong>Steca</strong> Compact series is specially designed for hybrid systems.<br />
The devices consist of a sine wave inverter with a high overload<br />
capacity, a battery charger and a transfer system. The in-built multifunctional<br />
contact enables you, for example, to start a diesel generator<br />
to recharge batteries or to cut the power for less priority<br />
loads when the battery is lower than a given threshold. Even if you<br />
only use the device’s sine wave inverter, <strong>Steca</strong> Compact is still very<br />
cost effective. The integrated power sharing function ensures that<br />
the transfer system always provides the connected loads with the<br />
desired power.<br />
