Proposed solutions
• Restart the inverter and wait until it functions normally.
• Disconnect the entire power supply
and shut down all components.
Disconnect the load and plug in to restart the components.
Then check whether the load is short circuited and
if the fault has been eliminated.
• Disconnect the entire power supply,
restart the inverter and wait until it functions normally.
• Check the input mode setting is correct.
• Restart the inverter and wait until it functions normally.
• Restart the inverter and wait until it functions normally.
• Check the grounding.
• Check if the ground resistance of PV+ and PV- is greater
than 2MΩ.
• If it is smaller than 2MΩ, check PV string for ground fault
or poor ground insulation.
• Check the input mode setting is correct.
• Disconnect the PV input,
restart the inverter and wait until it functions normally.
• Have a suitably qualified specialist disconnect
the grid, battery and PV input
and check whether the bypass relay (F9)
or the grid-connected relay (F14) is defective.
• Restart the inverter and wait, until it functions normally.
