2Kw inverter genny for MW, coffee and supplemental charging.
Inverters; 1200, 400, 100. The 1200 can be used for coffee.
The genny also does bulk charging when the solar falls behind.
After a day of sightseeing, the van can be used to supply both AC and DC as the three batteries are charged by solar and alternator.
With the 7-pin I can join the TT and TV to share DC across the batteries and the panels.
