This was case referred to us by Havells solar where 20kVA solar inverter was to be protected from over voltage issues.
The OVCD is connected before the AC DB , so it protects even the SPD, which generally changes colour frequently (trips) if exposed to over voltage situations
OVCD is meant for protection against extreme over voltage and sustained/ continuous overvoltage
Beauty of this product is that it can withstand 440VA in any individual phase for indefinite period of time. So problems like neutral open and double phasing will have no impact on connected load.
Cost of this unit is only 10480+ GST 18%
