Have you tried unplugging / disconnecting everything that is plugged into your power outlets?...Just re-read your original post and you say the fridge is the only thing running off the system- does the solar controller still cut out if you unplug the fridge? Can you plug the fridge into the cig lighter on the car and see if it works there?
Any chance some muck has got into one of your power sockets and shorted it out?

Thanks, yes have removed everything and still getting issues. There are quite a few ants around and I'm wondering if they are the problem. But having difficulty figuring out what circuit runs what. It isn't very obvious.

Hi Andrew and as suggested earlier in this thread, go get yourself a cheap digital multi meter and we can then talk you through the fault finding and fix procedures.

Does the controller have electronic over current protection by any chance?

Thanks all, we lost our comms for a few days. I just shut everything down and used plan B. We are headed back to Sydney now and I am taking back to the manufacturer to get them to sort it out.

Thanks for all your help but I will always take a multimeter with me from now on.
