Help for self build electrics solution for off grid camping

[Talbot]

My son has bought a Boxer van for conversion and I'm wondering what components are required to implement a system on a tight budget.
I have given him a Sterling B2B battery charger which was redundant in my garage and he has ordered a 200w solar panel kit from Amazon. Does he still need a split charge system. Also what does he need to have 240 volt hookup etc. It's a blank canvass.

He intends to run a 12 volt fridge, 12 volt fan on a diesel heater, lights, charge phones and laptop. Any help greatly appreciated.

He'll be buried in good, practical advice if he checks out the sister site https://motorhomebuilder.com/

When I was at the library last week I noticed they had a Haynes manual written by John Wickersham, "Build your own motorhome".
