Table 6-1 : Error Message
ERROR
Possible cause
1. Check the utility frequency
2. Check Grid Code setting
3. Contact our customer service for
technical support
1. Check the utility frequency
2. Check Grid Code & Grid setting
3. Contact our customer service for
technical support
Grid connection of inverter need to be
far away from non-linear load if necessary
1. Check the AC connection in accordance
with the user manual
2. Contact our customer service for
technical support
1. Switch on AC breaker
2. Check the connection in AC terminal and
make sure it connects to inverter
1. Check the utility voltage within the suitable
range
2. Check Grid Code & Grid setting
3. Check the connection in AC terminal
4. Contact our customer service for
technical support
1. Check the utility voltage within the suitable
range
2. Check Grid Code & Grid setting
3. Check the connection in AC terminal
4. Contact our customer service for
technical support
1. Modify the solar array setting, and
make the Voc less than 1000Vdc
2. Contact our customer service for
technical support
1. Modify the solar array setting, and
make the Voc less than 1000Vdc
2. Contact our customer service for
technical support
1. Check the insulation of Solar inputs
2. Check the capacitance, dry PV panel
if necessary
3. Contact our customer service for
