I have I solar panel on the roof of my van. With a MPPT chargecontroler I charge my 12v semitraction battery. This battery provides my 500watt inverter which provides my fridge.
My inverter has a max voltage input of around 15v and then that over voltage protection kicks in. I have to reset the inverter manually.
This happens when there is a big cloud passing on a sunny day. When the sun comes from behind the cloud the chargecontroler has a output spike around 14.8 volts for just a brief moment.
I measured this with my arduino taking samples every 500ms.
So is there a way I could even these spikes out so the overvoltage won't kick in? I know for arduinos we use capacitors to smooth things out, would that work here too?
I can specify the panel inverter and battery if needed.
