My "integrated" 240v off-grid solution

After much planning and reading up I managed to wire in this solution, which allows:
  • Use the 240v socket on the kitchen end panel when not on hookup
  • Recharging at 300watts~ via the alternator
  • Control via a single app over bluetooth

Main items:
  • Anker SOLIX C800 Portable Power Station - 768Wh | 1200W (boosting to 1800W)​

  • Victron Orion-Tr DC-DC Converter Isolated 12/24-Volt 15 amp 360-Watt​

  • Halfords 12v Relay​

Firstly I attached a positive cable coming off the split charge relay (pre-relay) under the drivers seat, shortly after the run I added a 12v isolator switch which can be reached under the seat. I then ran the cable inside some flexible conduit under the seat and down the back of the van, running alongside the kitchen unit, this is fairly well hidden under our carpets/mats.

I then made a small wooden box to house the DC-DC converter, which includes a 12v on/off control which I wired to the relay and the power station "car port". This box is secured to the floor through a connection to the rails.

Then into the power station I have the positive coming directly from the alternator with a negative coming from the rear leisure battery via the solar input. I drilled holes into the rear leisure battery cover to run the negative plus the 240v cable. I figured this panel was easily replaceable so best to make a hole here rather than anywhere else.

The 240v cable comes down from behind the hook-up isolator panel, this panel was tricky to remove and tap into but I got there eventually. The cable coming immediately off it is connected to a socket, allowing me to disconnect it if anything goes wrong. The cable for this part is routed into the wardrobe area and then down through the fresh-water access lid which also received a drilling.

How it works:
To turn on the 240v supply I open the app and tap the "AC Output" button, this runs 240v into the kitchen end socket.
I have this set to turn off automatically after a period of idle use.
To recharge I select the max charge setting from the overhead panel in the california, ensure the leasure batteries are at a decent level, then turn on the "car port" switch in the same app which triggers the relay in the DC-DC converter that then recharges the Power Station via the alternator.
When the whole system isn't in use I flipped the isolator under the passenger seat to disconnect the alternator cable from the DC-DC converter.


If anyone has any questions about it please feel free to ask, but note I am not an electrician.
