I have recently had fitted a 200w solar panel on my Hymer B544. I also had fitted a LR1218 Schaudt controller. I have absolutely no real understandings of electrickery and have made a couple of observations which I don’t know if someone would have the time to comment on or whether you could point me in the direction of someone that could.
The first thing I have noticed is that when the Dometic fridge is in `Auto’ or `12V’ there is a buzzing alarm type sound when the engine is running. I originally put this down to the fridge having been switched off and being below operating temperature. So I switched it off until I got home and put it on hook up to get it back to operating temperature,
but it still buzzes with the engine running.
The other thing I noted when travelling back home was the readings on the display. The first two are when we stopped at Gordanos services at around 11pm when we switched the 12V back on for a rest stop. I noticed a low reading on the batteries so I started the engine and the next two photos represent with the engine running. Due to the fridge buzzing in the `Auto’ or `12V’ mode I travelled back with the fridge in `Gas’ mode.
The last two photos were taken yesterday at home during the day were the battery readings seemed to have recovered. Is this to be expected or because I was in `Gas’ mode was the fridge draining the battery? Any advice would be appreciated.
Thanks
