Hi.

The explanation I received is that this normally occurs when the load for the inverter is too high when there is no Grid available. Client must ensure that the backup load connected is in the allowed inverter specification. To remedy this, the client must switch off some of the appliance/loads especially during periods when there is NO GRID available. Or they can add additional battery or generator to support the load.
