5 - Troubleshooting
If the measured insulation resistance is less than 1Kohm the inverter does not connect to the grid due to a low
insulation of photovoltaic module respect to ground.
The insulation resistance is affected by the environmental conditions the photovoltaic module is in (E.g.: pho-
tovoltaic module wet from dump or rain); therefore, the measurement must be made immediately after the
anomaly.
