5.1. Start Up aNd ShUtdOwN.
EQUINOX LV solar inverters require an accurate start up procedure.
Read this section, before start it up; follow the steps in order.
to not follow the steps in appropriate way can
damage the equipment.
5.1.1. first start up.
The following procedure describes the steps to start up the equipment.
1.
2.
Turn on DC power to the inverter (turn the switch that disconnnects
the system to ON). LCD panel will light. Now power
from panels is available. The start up mode of the inverter
includes a test of 10 seconds for fans, later on they will be
shutdown when ending the test.
Turn on AC power to the inverter (turn the AC circuit breaker
of the system to ON).
Standby mode (SB)
Inverter is set to validate voltage and frequency from grid
during a limited* period of time before connecting to grid itself.
During this period, voltages from grid and from photovoltaic
panels are monitored. After this period of time, inverter checks
the available power from panels by generating an AC voltage
synchronised with the grid. Inverter will only be connected to
grid if it can generate the required voltage.
generation mode (gEN)
Once it is connected to grid, the inverter will always track the
maximum power point of photovoltaic panels**, starting from
their open circuit voltage.
* Period time of grid checking depends on the local regulations.
** MPPT voltage depends on the matrix configuration of installed
panels.
If the inverter does not start up after the period time of
grid validation, check the fault message in the LCD panel
and consult the Troubleshooting section of this manual.esta en

5.2.1. Modes of Lcd panel and their functions.
Lcd panel
LCD panel works in sleep mode to reduce its consumption and increase
its useful lifetime. Wake up mode can be activated through
two ways:
fig. 6.
Detail of LCD panel.
Generating Wake/Scroll
Earth Leakage
a. Pressing button wake/scroll, or
b. with the initial application of voltage* from panel set, and voltage*
from panels when sunrise.
* Voltage from panel set has to be higher than 30 Vdc to activate the LCD panel.
LCD panel will return back to sleep mode after 5 minutes.
LEd indicators
• Generation (blue) - inverter is reinjecting power to grid.
• Earth fault (yellow) - there is an earth fault in the system.
• Fault (red) - this indicator works in these two modes:
Continuous - it means a failure that could require service
for the inverter or other parts. In most of the cases, this
fault would mean a temporary fault, of frequency or voltage
from grid, or due to a decrease of sunlight conditions. These
faults are usually cleared automatically.
Blinking - it means a critical fault that require an intervention
in the inverter.
wake/Scroll button
This button makes the following functions:
• Press once the button to wake up the LCD panel.
• Press it again to display the next message in the LCD panel.
Repeat it till see all messages. Consult the meaning of each
one at table 1.
