How much resistance does a solar inverter have?

A well insulated solar circuit, even in soaking wet conditions, we would expect to measure at least 20-30 Megohms of resistance. Solar inverters will begin to raise alarms and stop generating at around 1 Megohm. What causes Ground, Isolation (ISO), RISO low and Insulation Faults?

What does a fault message mean on a solar inverter?

Inverters constantly measure the value of the ‘insulation resistance’ between the solar panels and the earth. If the value is too low, the inverter displays a fault message. What exactly does this message mean? Error message on the inverter display or in the monitoring with a text such as 'Insulation resistance' or 'R-iso'.

What does a solar inverter do?

In addition to converting direct current (from the solar panels) to alternating current (in the grid), inverters perform a whole range of tasks. One of these is the continuous monitoring of the resistance between the electrical cables on the side of the solar panels and earth.
