Hi Nate, would you be able to use this same wiring diagram but change the breakers in the power distribution panel to give out 240V AV rather then 120V AV as I’m in the UK and we us 240V AV for household items.
For the most part, yes… You’d need a 230v Victon Multiplus as well; but most everything else should, for the most part, be the same.
hi nate, i am gathering items for my 2020 Ford Transit build and plan to purchase one of the your consulting program. i wanted to start buying my electrical components based on my power audit i decided to go with 200 amp hour with 300 watt solar. my question, is it cheaper if i purchase the bundle package ? and can i use 2- 160 watt rich solar panels instead of 3 – 100 watt? i am trying to save as much space as possible on roof.
thanks
This is similar to what you are proposing: https://www.explorist.life/200-amp-hour-350-watt-camper-van-solar-kit/
