We recently got our $500 fixer upper pop up camper and our two Enjoybot 100ah 12v batteries. The camper does have a blown power converter that is older than dirt. What we were possibly considering was replacing the whole power converter setup with a Sungoldpower 24 volt 2000w inverter and then using a 24 to 12 volt buck converter to drop the voltage for the 12 volt accessories. The loads include a water pump, propane furnace, ammonia fridge, and lights that are eventually going to be replaced with LED's. We're not sure how much power everything is using as we haven't ordered a shunt but going to other info online we would say about about 350ish watts without the fridge in 12 volt mode.
Would using something like this be safe or are they not meant for sustained loads? The main reason we would prefer to use 24 volt over 12 volt for the solar and inverter is because of the reduced cost of wiring and being able to use a smaller (and less expensive) MPPT. I do understand that we wouldn't be able to use a DC to DC charger which is fine because we will have solar and the truck we are towing with only has a 4 pin connector (the camper has a 6pin square but no brakes). Other than that what could be the potential downsides to setting up a system like this? We wan't to maintain safety above all else and it seems like going with 24 volts would be safer considering the lower amperage of the inverter and MPPT especially since it seems like the EPEVER MPPT charge controllers tend to blow up above 40 amps output according the the reviews.
