Yeah I think that’s right. From 900-300. And I would think it would not run near as much at night. I guess the real test will come when I try it! LolIt all depends on average (or steady-state) draw by the mini-split.
PV has to produce all the power consumed. Batteries are mostly to provide power consumed at night.
Hopefully, heat load is less at night and much less power is consumed 8:00 PM to 8:00 AM.
I think I saw spec for one mini-split and power consumption varied 3:1 (900W down to 300W), but BTU varied 8 or 9:1.
That would mean a fraction the efficiency at lower power, and you'd be better off cycling it on and off. Might consume 1/3 as much energy that way.
