Hi all,
My builder is giving me for free a 1.5kw inverter with panels, I asked him if I can upgrade to 3kW and he said yes for $2200 extra.
So thats only for interter upgrade.
Does that sound reasonable? How many panels on a 1.5kW and how many more do i need to add for 3kW ? Panels will add later.
Your thoughts on costing please? is 2.2k reasonable? for 3kW.
Regards
