Newbie like a deer with no eyes...

I apologise profusely, but I really have 'No Eye Deer' how solar panels, 'Killerwasps' and solar regulators work, but I do like having a go at things...

I'm setting up my caravan and have mounted 3 X 175 watt panels on the roof.

The plan is they will feed into 2 X 120 amp deep cycle batteries to run my fridge during the day, that draws 12 amps.

The specs of each panel is:

- Max Power Current 4.93 amps

- Max Power Voltage 35.5 volts

- Open Circuit Voltage 43.5 volts

I know I need to feed the power generated into a Solar Controller, I just don't know which one would meet my needs.

Any advice will be greatly appreciated...

Again, my apologies...


Thanks, Greg in Australia

That sounds like an absorption type fridge?

Not much love for those.
