Classic 150SL for 1360 watts on an RV

[harryn]

If you keep using your RV the same way that you are using it today, there is no advantage to moving it away from the 12 VDC / 120 VAC setup you have today.

The advantage of a 24 or 48 volt system will only make a significant difference if you ever want to be able to run air conditioning from the battery pack sometimes without using shore power or the generator.

For most people, that is not useful, but there are an increasing number of locations that ban generator use at least during the night time, and it can still be quite hot out.

Even if you do plan to use a 24 or 48 volt setup for the inverter, usually the rest of the coach remains 12 VDC  120 VAC - it is just easier to leave it that way.

Good luck
