Goodwe MT series User Manual

Note:
When sunlight is insufficient, the PV Inverter may continuously start up and shut down automati-
cally due to insufficient power generation by the PV panel.
1. Turn off DC switch of the inverter.
2. Wait till the inverter's LCD light is off.
3. Turn on DC switch and make sure it is connected.
4. If the problem still exists, contact local service office for help.
1. Turn off DC switch, take off DC connector, measure the voltage of PV array.
2. Plug in DC connector, and turn on DC switch.
3. If PV array voltage is lower than 250V , please check configuration of inverter
module.
4. If voltage is higher than 250V , please contact local office.
