solar panel fault
Solar Panel Isolation Fault, Here''s a Common Cause!
Its likely your solar panels are starting to fail. The moisture from the dew in the morning or rain causes the DC of the solar panels to leak to the earth on the array frame. The inverter then senses the fault and shuts the system down for safety. Once the moisture has burnt away (evaporated) from the sun the system will then start to work again.
