I received a call from a person who was not a customer of mine asking to connect up his 8 kW PV system.
Its a new build and the modules were installed when the scaffolding was up, this was several months ago.
System is 2 x ABB PVI 3.6-TL-OUTD inverters connected to 32 x 250 watt modules. The inverters are installed in the loft area and two twin & earth's have been installed back to the C/U.
The original installation company did not complete a G59 application and I have just done this but SSE have come back and they want ÂŁ20k to upgrade their transformer and then they will allow the full 8kW to be connected. Obviously, my customer is not going to pay ÂŁ20k !
He could just connect up one system but as its a large house with a wedding venue attached to the same supply he would like the full 8kW connected.
There is a system manufactured by Siebert but this needs a data wire installed from the intake to the inverters which as the house is nearly completed would be impossible to install without a lot of damage to the house.
Can anyone think of a way that would limit the total export to 3.69 kW which would keep the DNO happy ? off the top of my head I was thinking of some sort of battery system that one of the inverters could be connected to and then it would discharge via a transfer at night ??
All thoughts appreciated.
