Solution
1. Resistant of AC cable is too high.
Change bigger size grid cable.
2. Adjust the protection limit if it’s
allowed by electrical company.
1. Check connections and grid switch.
2. Check the grid voltage inside inverter
terminal.
1. Reduce the module number in series.
1. Restart inverter.
2. Change power board.
1. Check P V input connections.
2. Check D C input voltage.
(single phase >120V, three phase >350V)
3. Check if PV+/- is reversed.
Inverter no power
on L CD
No power
LCD show initializing
all the time
Can not start-up
1. Check if the connector on main
board or power board are fixed.
2. Check if the DSP connector to
power board are fixed.
1. Check inverter surrounding ventilation.
2. Check if there’s sunshine direct on
inverter in hot weather.
1. Use user define function to adjust the
protection limit if it’s allowed by
electrical company.
1. Check inverter inductor connection.
2. Check driver connection.

DC input overcurrent
1. Restart inverter.
2. Identify and remove the string to the fault MPPT .
3. Change power board.

9. Troubleshooting
1. Remove all DC input, reconnect and
restart inverter one by one.
2. Identify which string cause the fault and
check the isolation of the string.

NOTE:
If the inverter displays any alarm message as listed in Table 9.1, please
turn off the inverter (refer to Section 6.2 to stop your inverter) and wait for 15
minutes before restarting it (refer to Section 6.1 to start your inverter). If the
failure persists, please contact your local distributor or the service center.
Please keep ready with you the following information before contacting us.
1. Serial number of Solis Three Phase Inverter;
2. The distributor/dealer of Solis Three Phase Inverter (if available);
3. Installation date.
4. The description of problem (i.e. the alarm message displayed on the LCD and the status
of the LED status indicator lights. Other readings obtained from the Information submenu
(refer to Section 6.2) will also be helpful.);
5. The PV array configuration (e.g. number of panels, capacity of panels, number of strings
, etc.);
6. Your contact details.
Reve-DC
One of the DC string is
reversely connected
1. Please check the inverters’ PV string polarity,
if there are strings reversely connected wait for
the night when the solar irradiance is low and the
PV string current down below 0.5A. Turn off the
two DC switchs and fix the polarity issue.
Screen OFF
with DC applied
Inverter internally damaged
1.Do not turn off the DC switches as it will
damage the inverter.
2.Please wait for the solar irradiance reduces
and confirm the string current is less than
0.5A with a clip-on ammeter and then turn
off the DC switches.
3.Please note that any damages due to wrong
operations are not covered in the device
warranty.
