HI
I am sorry, I feel as if I am bragging.
But everything I had read about G99 forms was super scary and stressing me out loads.
And I just wanted to share, I followed the guidance found in other threads and submitted my G99 A1-1 form to my DNO, (NG or was WPD) via email at 8:30 pm last night, and at 11:30 this morning I got my approval
Has anyone got theirs back quicker than that ?
it's not that hard or scary, you don't need to pay someone hundreds of pounds to do it for you.
unless you want too.
I am installing a Multiplus II 48/5000/70-50 230V with a 5kW 48V battery and a small solar PV system
Below is the main part of the G99 A1-1 form and my line diagram (a modified version of the one craigc posted)
I also attached the new 31 Mar 2023, G99 test certificate issue 1 amendment 8 (PDF Document - 857 kB) off the Type Test Registery.
It was as simple as that...
HTH, someone
