I have off-grid system powered by 2x160W monocrystale PVs, Smart MPPT 75/15 and (currently) 12V 74Ah Ca/Ca flooded lead-acid battery.
This system powers one WiFi P2P link, and one CCTV.
I noticed that controller shows consumption around 0.2-0.3A all the time, no matter if CCTV IRs are on or off. How it can be possible?
I measured consumption of CCTV with multimeter, and it is 0.16A without IR, while with IR it is about 0.34A
On top of that, there is WiFi P2P link, by I didn't measure its consumption yet.
My expectation of load during the night is 0.5-0.6A, but controller shows 0.2A only.
What am I missing here?
