Hello, I'm left scratching my head at the numbers. Am I mathing correctly? 35v x 8a = 227w? Shouldn't it be like 280 watts? I tested the solar panel at the leads and I'm getting good voltage, even with 40ft extension cables, the numbers are still good. I'm using a Cen-Tech basic clamp meter for testing.
Here is what I'm working with:
Growatt 3000lvm 24p
Bigbattery 24v Mule, 3Kw
40ft 12awg extension cables
(1) TrinaSolar 390w 144cell:
Imp 9.64a
Vmp 40.5v
Isc 10.08a
Voc 49.7v
Mono, 12awg wire
Panel lays almost flat (10°), I thoroughly inspected panel for snail trails, corrosion at the connections between solar cells, nada. Panel is good.
My concern is I'm not getting enough watts to power my little a/C unit which uses about 400watts (measured with a Kill-a-watt meter)
I expected to only ever get maybe 330 watts on a clear day at noon ish, but the most I've ever seen is 270watts on the display.
Any advice would be appreciated. BTW, first solar setup, and I'm new to this all.
