For fan temperature controllers I use these: ebay No pot twiddling required . I do use a 500A battery switch to bypass the charge resistor, it gets switched on manually when, around 50V, a green light turns on. It never gave problems regarding switch spikes, I never bothered monitoring them either. The green light (and low voltage disconnect) is managed by a battery monitoring IC. AC over current is monitored by one of the little toroidal sensor coils, I use that to turn off the inverter ON switch electronically. It requires a manual reset - don't trust automatic re setting for that. There are just DC circuit breakers, no hi power fuses, in my inverters. Yes, this has possibly contributed RUD mosfets in the past but that prompted me to improve the design and, thanks due the input of our resident engineer, the inverter runs trouble free now. But that does not stop me from tinkering on one of them , mainly to make it more compact. You like programming, I understand why you get your Nano to take on many tasks about monitoring. I like doing PCB's and the mechanical aspect of inverter building. So we both have fun with it .
