I'm a bit confused by the numbers and how they stack together.
originally i was getting two powerwall 2 but its been changed and i'm getting a powerwall plus and a powerwall 2 for free and am looking to add on some panels. the powerwall plus has its own inverter.
i'm not too worried about blackouts, the grill is quite stable recently. i'd like to just get my pge bill down or erased.
I bought 26 Longi Hi-Mo-5 panels. 411w with up to another 140w bifacial gain.
the inverter on the powerwall plus is:
am i looking at the "maximum input voltage" of 600 / 48 = 12.5 panels per mppt?
or
operating input range 550 / 48 = 11.45 panels per mppt
or PV mppt voltage range of 480 / 48 = 10 panels per mppt?
i feel like i should max out 3 mppts. probably do a run facing west or at least south west and two facing south. how many more panels do i need to buy?
i used to grow weed so my previous usage is worthless. i've also added a mini split a/c that i wont use a ton as my house stays cool (concrete slab floors, it drops to 55° at sunset and i run a whole house fan to cycly in the cool air but a few weeks it does get stupid hot). so its hard to know my usage. i based off my last 5 months with a hot tub then added about 30%
