'Off Grid' inverters and G99 certificates in UK

[shavermcspud]

My DNO is NationalGrid, according to https://www.energynetworks.org/customers/find-my-network-operator

I am now thinking about going for an 8kW SunSynk inverter, rather than two 5kW SunSynk inverters. The 8kW allows 28A Max PV Isc and 22A PV Input Voltage,, and since the 5kW only allows 17A Max PV Isc and 13A PV Input Voltage, I don't expect I'd get more than 8kW PV from my 12kW solar panel array with two 5kW inverters, would I?

I had no idea a G99 would take two days, I thought it was four to six months!

I did a G99 with NGEC as they're soon to be known and approved in two days for a 6kW inverter. Happy to help with paperwork just DM me
