I’ve been experimenting to see what would be required in the way of power needs, to run my Vantage 82 litre fridge/freezer on solar power. The specs suggest that a 200w panel and a 20amp MPPT controller coupled with a 150ah deep cycle battery should do.
So now I have a 260w panel mounted on the roof tray. Its hinged on one side so that I can tilt it, or just lift it up to get underneath it for whatever reason.
This panel is feeding a Tracer AN Series 20amp MPPT Controller which feeds a pair of 85ah deep cycle batteries wired in parallel.
The setup seems to be holding its own against the 6amp consumption of the fridge-freezer at 14.1v. I’ve yet to try it on a cloudy day. Its hot and sunny this week.
