Inverter Problems/Head scratcher
I have a little bit of a head scratcher. I have 600w of PV array going done through an 40amp MPPT to a battery bank of 558 A/H. From there it runs a 3000w Mod sine wave to run my fridge and soon hopefully my freezer as well.
This all works well except for this part (Here come the head scratcher part).
Over the last couple of months, the fridge has worked well, the small ice compartment making enough ice for the whiskey (all just the essentials) .. but we have had some serious hot and bright days lately and now the fridge will only run at night when the voltage drops to below 13.5v, it starts and almost immediately switches off again. I thought that maybe a voltage regulator in the form of an old PC UPS would help but no luck..
Any Ideas.. (I can't drink whiskey with out ice, that is just cruel and unusual punishment) :
