Hi, we have a Truma N3145 absorption fridge/freezer. I am hoping that my complicated question is easy for someone to answer!!
Earlier this year, we did the 8 hour Portsmouth to St Malo crossing. When we got back in, the fridge was still on auto and was stroppily telling us with error code 3 that the gas wasn't on. We had disconnected it, of course.
Which led me to wondering. How could I power the fridge, on low, to at least keep it burbling away. I uprated the battery from a 100ah lead acid, to a 300ah lithium. I already have an inverter fitted.
The markings on the fridge say:
Gas, 420 g/24
230 v, 220w
12 v 190w
Currently, the fridge will then work on mains electric through an EHU, 12v electric when the MH engine is on. And of course gas. My question therefore is:
Can it run off the 12v lithium battery?
or
Can it run off the 230v main, but via the inverter? I've tried, but the inverter doesn't seem to want to know.
Is there a way of putting in a switch on an independent circuit that connects the leisure battery directly to the fridge? Ideally, I want a simple solution so I can use the 300ah in the lithium battery, on a ferry or anywhere, where gas is not allowed to be used.
Cheers,
Dave
