5.Troubleshooting
This chapter introduces how to start and shut down the inverter.
5.1 Startup
Step 1 Switch on the DC switch (optional) and DC switch in the project site. When the PV
arrays provide enough startup voltage, the LCD will enter the main interface.
Step 2 Switch on the AC switch between inverter and grid. If the alarm indicator doesn't light
on, the LCD will show "current status: standby".
Step 3 When the DC and AC supply power normally, the inverter will prepare to start. At first,
the inverter will check the inner parameters and AC grid parameters, if they are in the normal
range, 60s later, the inverter will check the insulation impedance.
Step 4 About 60s, the inverter will generate power normally. The grid connection indictor will
be on and the LCD will show: "current status: grid-connected".

5.2 Shutdown
Step 1 Switch off all switches.
Step 2 Wait for all indicators off.

6.Maintenance and Troubleshooting
6.1 Maintenance
The inverter needn
’
t to be maintained regularly, but the sundries or dust may influence the
heat dissipation performance, so, use soft brush to clean the inverter. If the surface of LCD
and LED indicator is too dirty to read, use a wet cloth to clean them.
HIGH TEMPERATURE:
During running, do not touch the inverter. The temperature of some parts on the inverter is too
high, and may cause scald injury. After shut down the inverter and wait until it cooling down,
then do the maintenance and clean.
CAUTION:Do not clean the inverter with any solvent, abrasive material or corrosive material.
