Hi
Wondering if it is possible to buy 12v meter that plugs into lighter socket and if so would it be reliable? Want to
check battery voltage while using fridge from main battery.
Thanks

The problem with ciggy voltmeters is when they are used on a circuit which also has other items running off it in parallel with the meter, the battery voltage may be 14.4v when engine running, but resistance in wiring circuitry because of any load, ie, relays and other items on the same circuit as the Ciggy plug will mean a lesser voltage is read on the meter.
Hard wire to the battery bypasses such items and provides a more genuine reading.

Lots of experts here telling him what not to do, maybe you could assist with a realistic solution. I am clealy not an expert but I will suggest that you try an invertor with a hard wire option, such as xantrex, seem to hold up to corrugations
well, and hav it wired in by your marine elec. 300 or 400 ah lithium should run a small a/c for your purposes and the solar panels you suggest should keep up with replenishing. I do,have lithiums and know how quickly they can be recharged.
