Hi, I have this system, 12v
100 amp hr Renogy Smart Li batt with self heating
Renogy 40 amp MPPT Li charge controller
Renogy 1000w Pure sign wave inverter
2 x 100 watts NOMA solar panels
The 2 panels are connected in parallel (want more amps, with voltage the same)
I can get 2 more of the exact same NOMA solar panels, to make 400 watts total and would like to add them in via parallelization on my fuse block.
My charge controller can handle 540 watts in on the PV, so I'm not over that.
Would having a 100 amp hr battery be a problem here? Or do I have to get another battery also?
From what I've read, in terms of sizing, my solar panels are slightly bigger than my battery, by about 25%, for example, 300 watt is more suitable for 100 amp hr battery, I realize the disadvantages of going too small of a PV system, but is there any harm of them going a little bigger?
Thanks
