We are transforming an old (1997) American School bus to a Campervan / RV / Mobilehome.
We decided to use a 12V system (so no 24V or 48V) because of all kind of equipment we already have.
We have installed 18 flat and bendable solar panels (100W - 18V from a Chinese vendor) on the roof, they are all connected to a Victron Smart MPPT 250/100. the potential total capacity would be 1800W exceeding the 100A (12x 100W = 1200W), but keep in mind that these are Chinese (Ali Express), our tests show roughly 50% - 60% of their specified '100W' performance on a sunny day.
We also bought the following items:
Victron Smart Lithium 12.8V / 200Ah battery
Victron BMS VE.Bus
Victron Smart Phoenix Inverter 12V/3000W
Victron Smart Battery Protect 12V/220A
Victron Smart Phoenix Charger 12V/50A (1+1)
The idea is be to fully off-the-grid capable, even on days with less sun (therefore the solar panel overkill, and because we simply have a very big roof).
I do have quite some experience with electric systems in general (both AC and DC) but I'm not 100% sure about the VE.bus wiring. So it would be very helpfull if someone could help me with some wiring schema / diagram.
