Think I’m finally happy with the electrical system, aka my favorite part….
All the chargers are now Victron. I also now have two 100ah LiFePo4 batteries in parallel for 200ah total, have the big fuses all in one place, and made it easy to just disconnect all the off grid charging stuff when I have shore power available.
The amount of stuff packed in there actually equates to a fairly efficient system (1/4 of it is my toolbox though). I have two solar charge controllers as I have two different size panels (two 100 watt panels and one 50 watt panel) so the total current is not limited by the smallest panel panel. I decided to use two inverters instead of one big one. I have a 375 watt inverter which will handle a vast majority of my needs, efficiently, (even my electric blanket) but in case I want to use the toaster oven, or the bigger space heater off-grid, I can use to the 1000 watt inverter (the bigger the inverter, the more ambient power use, even if not being used).
When the van is running, I have a 30 amp DC-DC charger that powers and charges the all van stuff from the alternator.
On-grid, I have a 25 amp charger/power supply that keeps the batteries charged and handles all the 12 volt stuff (including the refrigerator). The AC stuff can be moved to the shore power connection (I have a power strip under the seat that comes from the plug on the outside of the van).
Inside I have a Raspberry Pi with a touchscreen running the Victron VenusOS that lets me monitor and control the entire electrical system.
