6 FAQs about [Photovoltaic inverter fault code 010]

What is error code 010 in Sungrow inverter?

What does error code 010 mean on an inverter?

If the circuit breaker protecting the inverter trips, it will show the 010 code. Re-set the circuit breaker and allow the inverter to restart (takes 60 seconds). When error code 010 occurs intermittently, and it is not caused by power interruptions, it may be due to a loose AC conductor connection or incorrectly fitted plug.

What does error code 010 mean?

Please observe all OH&S regulations when working on Sungrow equipment. Error code 010 refers to the AC grid supply being cut to the inverter. This document uses an SG5K-D inverter as an example for explanation. When the grid goes off, the inverter will shut down as per the required standard.

What if grid voltage is below the protective value of error 004?

The grid voltage is below the protective value, which is lower than the protective value of error 004.(stage II) This is a short-term fault due to grid condition. Wait a moment for inverter recovery. AC over-current.

What happens if fault code 010 is notified through the app?

In the event of Fault code 010 being informed through the App, the following corrective measures shall be taken: Grid Power Outage (Islanding) (Code 010) The grid is cut off or the AC circuit breaker is tripped. 1. Check whether the AC wiring is secure, including the AC distribution cabinet wiring. 2.

What if grid voltage exceeds a permissible range of inverter protection parameters?

If the grid voltage exceeds the permissible range of inverter protection parameters, ask utility grid company for solution. 3. If the grid voltage is within the permissible range, contact Sungrow Service Dept. Transient over-voltage. The grid transient voltage exceeds inverter allowable upper limit. This is a short-term fault due to grid condition.
