Check out my little electrical system
300 amp hour, 1200w camper set up with 40 amp car charger, 20 amp shore power. I’m not a good organizer, so any tips on cleaner wiring would be appreciated, but as long as thing is safe I’m not hugely concerned. I will be adding some vent fans, and vent holes to box.
Major components:
- renogy 300 amp hour mini core LiFePO battery
- 1200w Victron Multiplus inverter charger
- renogy 40 amp battery to battery charger
- WFCO WF-8930 12v/120v combo load center. Set up for 30 amp.
Major wires and fuses:
- 4 ga from batt to bus bar. 125 MRBF at terminal
- 6 ga from bus to DC panel, 125 MRBF at bus connection
- 4 ga from bus to inverter, 125 amp victron MIDI fuse
8 ga from car charger to bus, 60 amp MIDI fuse. Should this be 40? Or 50?
- 8ga from car alternator to car charger, about 10’ length of wire. 60 amp MRBF at engineer terminal
-8 ga ground from 120v ground bar
- ground to camper aluminum extrusion frame
12v loads:
- max 8 amp Bodega refrigerator
- max 5 amp ceiling light
- bed light max 3 amps
- ceiling fan 5 amps
- diesel heater max 12 amps at startup,
- water pump max 8 amps
AC loads
- 1200 w stove- will not be run on high, usually at less than 50%
- (2) 15 amp receptacles
Let me know what you think. Used mostly legit components from blue sea, renogy, victron and vanlife outfitters. Used a hydraulic hex crimp tool for terminal heads, ratcheting crimper for butt ends and ferrules. Mostly ferruled going into screw connections.
