green indicator flickers, other indicators are off: inverter is powered on and under
self-inspection, wait for enough light to fulfill grid-connected condition
green indicator is on and other indicators are off: inverter self-inspection has passed
and grid-connected power generation is on – pilot run succeeded.
“Warn” or “Fault” indicator is on or flickers: inverter is powered on but system fault occur.
Refer to section 6.3 to check the fault code in LCD display, stop the inverter as per section
5.3, and rule out faults according to chapter 8. After all the faults are removed, repeat the
operations in chapter 5.
(6) Set the inverter time according to local time, refer to section 6.4.4 to complete time setup.
(7) The default DC input mode of inverter is “independent” mode; refer to section 6.4.4 to
check and set DC input mode.
5.3 Inverter stop
When it is necessary to carry out power-off maintenance, inspection and fault elimination on the
inverter, stop the inverter according to the following steps:
(1) Disconnect the breaker on inverter public grid AC side;
(2) Disconnect the integrated DC switch of the inverter;
(3) Disconnect the switch on PV string DC input side;
(4) Wait for at least 5 minutes until the internal parts of the inverter are fully discharged, and
complete the stop operation.
5.4 Daily maintenance and inspection
In solar PV grid-connected power generation system, iMars series grid-connected inverter can
realize grid-connected power generation and stop/start operations automatically day and light in
whatever seasons. In order to safeguard and prolong the service life of the inverter, it is necessary
to carry out daily maintenance and inspection on the inverter besides using the inverter strictly
according to this manual.
