- 12 years motorhoming, a lifetime of living
My type of motor homing will change next year, more off grid than on. With that in mind my motorhome will need better12 volt power, so fitting I’ll start by fitting solar panels, no real problem there, however with 12 volt A/V equipment what’s the better plan, fit an inverter with the correct 240 power to use the appliances ( the inverter itself will be powerd by the solar) or just use the 12 volt lines. I’ve tried in the past using 12 volt to run the TV (which has a 240 brick and a 12 volt input.) but it’s never worked properly, I tried leads both with and without a 12volt stabilizer built in. My sat receiver (Humax freesat recorder) is 240 only at this time but 12 volt ones with power brick inputs are now available.
The 12 volt line outputs in vans do very a lot depending on battery charge level, and looking at the scematics for the m/h the 12 volt line is only 10amp at best.
Would it be better to bypass any 12 volt socket outlets and make up a dedicated wired in stabilised power supply for all the A/V stuff with the correct output power tails for TV/sat receiver stuff etc. as long as the power output of the 12 volt line is not exceeded?
It seems a waist of power to go 12 volt-240volt-12volt. But if it gives a better more stable supply, is it the way to go. Pure sine wave inverters are not overlay expensive now and having 240 “on tap” would have other uses.
