Hi,
I am wondering if it makes any sense to wire a capacitor in parallel with my marine battery. I am running a small 120VAC bar fridge off an inverter connected to a 100 Ah marine battery. The battery is charged by 3-100W solar panels (wired in parallel) and it all works fine when the sun shines for at least a few hours each day. A couple of times I have run into several overcast days in a row and the battery charge has dropped down a bit. When that happens the inverter complains for a second when the fridge compressor cycles on but then works fine after that. It only happens when the battery is low and can't supply the start up power required by the fridge compressor. I am wondering if adding a capacitor in parallel with the marine battery would help to provide the required start up power when the battery is running a bit low.
Any experience or thoughts on this would be greatly appreciated. I recognize that adding a capacitor increases the risk of getting shocked so any thoughts on how to manage that would also be appreciated.
Best regards,
Kevin
