Sungrow inverter rule 21 compliance

Are Sungrow inverters compliant?

All Sungrow’s inverters are compliant with the standard AS/NZS 4777 related to grid protection requirements. Those standards dictate for example, that if the line voltage or frequency goes outside pre-determined parameters, the inverter must shut down and decouple from the grid. This also includes blackouts.

Which inverters are eligible for use under Rule 21?

Inverters that are eligible for use under Rule 21 are those that have been tested and certified under the new UL testing protocol known as UL 1741 Supplement A (SA). A complete list of eligible inverters can be found on the California Energy Commission (CEC) website. The list — which is updated monthly — contains over 3,200 eligible inverters.

What size Sungrow inverter do I need?

Sungrow offers single phase inverters with output capacities ranging from 2kW to 10kW. For a commonly used 5kW inverter, Sungrow provides the SG5.0RS and the SG5.0RS-ADA. While they seem similar, the SG5.0RS-ADA is almost twice the size and weight.

Why does my Sungrow inverter have an error Code 002?

It is quite normal for the grid voltage or frequency to wander outside those parameters, especially around mid-day, or if your house is at the end of a long supply service, and in these cases your Sungrow inverter may show a error code of, 002 (Grid overvoltage error), 010 (islanding error), or 014 (10 minutes grid overvoltage error) for example.

What should I do if a Sungrow transformer is not working?

However, in the cases where they are frequent or sustained and causing loss of output, Sungrow recommends firstly contacting your network operator and asking them to check or adjust the line voltage at the local transformer. In most cases this will solve the problem. The network operator may request information to confirm this.
