Ground Current - RCD — Ground current surge detected

Was bedeutet 76, 77, 90 ?

The inverter's internal hardware detected significantly high ground currents, possibly due to insufficient insulation to the ground. This is a safety concern.

• Insufficient insulation to ground
• Ground fault in the system
• Faulty RCD sensor

1. 1

   Turn the inverter's ON/OFF switch to OFF.

2. 2

   Wait five minutes for internal capacitors to discharge.

3. 3

   Disconnect the AC breaker.

4. 4

   Disconnect the DC inputs.

5. 5

   Reconnect DC strings one by one, turning the inverter ON after each connection, to identify the faulty string.

6. 6

   Do not connect strings with a ground fault to the inverter. A certified installer must fix it.
