SunMaster CS series:
Central String inverter
that fi ts your system
State-of-the-art specifications
Based on Mastervolt’s experience, know how and ongoing development
the SunMaster CS provides you with a very high effi ciency of more
than 98%. The improved Optima Cooling system guarantees effi cient
functioning of the inverter and low sound levels. For outdoor mounting
the SunMaster CS is equipped with an IP65 sealed electronics
compartment to provide optimal protection against water and dust.
A clear, graphical display with 365 day datalogger informs you about
performance and historical data.
Quick installation, easy maintenance
The SunMaster CS comes with a waterproof AC plug for quick and
fl exible installation. The integrated handles assist you to move the CS
with great ease and assure simple installation. The rubber feet on the
bottom protect the connections when the inverter is placed on the
fl oor. A mounting bracket for quick wall mounting is also included.
Once the SunMaster CS is installed it requires very little maintenance.
The fan module is removable for easy cleaning; the communication
drawer is fully removable for easy wiring.
Flexible and compatible
The SunMaster CS is compatible with any type of PV module and with
amorphous and thin-fi lm solutions using optional transformers when
required. The CS15TL, CS20TL and CS30TL models are equipped
with two independent MPP trackers for maximum output as well as the
fl exibility required for multi orientation or when the solar panels are in
the shade.
Reactive Power settings
Depending on local regulations, energy companies increasingly insist
on the supply of reactive power. With a specifi c setting on the display,
Mastervolt inverters are fully prepared for this.
® An information bulletin on the background to Reactive Power Control
is available on www.mastervoltsolar.com/reactive-power.

Options
Complete series of string boxes
The strings are connected in a string box,
which is installed between the PV array and
the SunMaster CS inverter. The high DC
loads and currents require top quality and
safe components. The varistors in the
StringMaster reduce the risk of lightning
strike damage to the PV array, cables and
inverter. The advanced StringMaster SW
Pro version also offers individual electronic
current measurements for each string.
String errors, such as incorrect polarity
or low currents, are automatically
detected by the system. These are then
communicated to the SunMaster CS
inverter, where they are immediately
displayed.
A detailed description of the benefi ts of
Mastervolt string monitoring is available at
www.mastervoltsolar.com/sunmaster-cs
under downloads.
CS IT20 isolation transformer
Manufacturers require certain thin fi lm
and back contact crystalline PV panels
to be earthed on the DC side.
The CS IT20 isolation transformer applies
these panels in the best possible way in
combination with the CS15TL and CS20TL
inverters. The use of high-quality materials
ensures an excellent output, while the
offl ine function reduces night consumption
to zero. The robust IP54 casing is suitable
for outside installation and fi tted with a
regulated fan with an easily replaceable
fi lter. The enclosure consists of several
individually removable parts that block
the hoisting eye from view and simplify
installation while keeping cables and
clamps easily accessible.

Why a separate string box?
• The IP65 string boxes are developed in accordance with HD60364-7-712
and EN60439-1, and come with clear safety instructions.
• Safe and practical solution; the string box allows you to switch the
PV modules on and off at close range.
• Saves labour and material costs by reducing up to twelve strings
to only two.
• Equipped with high quality components such as a 1000 V DC switch &
reliable 16 mm 2 connections, and placed in a fully assembled enclosure
with coupling nuts.
