FAQ | Find troubleshooting tips | Growatt USA

Analysis: All of Growatt''s on-grid inverters will take the insulation resistance test between panels to ground before starting up. If the positive and negative poles of the string are short-circuited to the ground, it will damage the inverter. Therefore, when the "PV insulation resistance is too low" occurs in the inverter, it needs to be dealt with in time.
