I am finding that most solar charge controllers have low Amp ratings(10-30A). I recently converted a mini-fridge into a chest mini-fridge and am running it off my lead acid battery connected to the charge controller rated for 20A. When the fridge initially kicks on, it pulls nearly 40A and the charge controller cuts off (does not exceed the compressor LRA rating). My remedy was to connect the inverter directly to the batteries and not through the charge controller. The only problem here is I lose the low voltage cutoff function from the charge controller.
Anybody have any suggestions here. Not a huge deal, i shouldnt have to worry about low voltage cut off if I have the proper battery capacity.
Could a capacitor after the charge controller alleviate this? If the capacitor capacity was high enough it could provide those initial few seconds of high current.
