[leann53]

Good morning Funster,s question just bought a ex BT ducato with 96,000 on the clock . In the back there is fitted a espacher heater 240 sockets hot water boiler so hoping to use them for my conversion. Anyway I digress the way I am thinking is to power the van of a bluetti ac200max has anyone done this ? Or should I go the conventional way lithium solar etc . Your fast knowledge and guidance most welcome.

If you don't need portable power then improve your battery bank or solar - more storage and more harvest of power? I moved my old leisure battery to under a dinette seat so I could have two matching batteries to replace the single original. Added a floor vent and new straps to hold down. Doubled our reserves not not a lot of money.

It's an option. 12v and 240v power all in one. Solar input and mains charging included.

The only thing missing is how to charge it from the vehicle when driving.

A modern lithium installation will have a B2B charger, taking power from the alternator, which can be 20A, 50,or more. How will this charge? It may be limited to 8A through a 12v cigarette lighter socket,and they aren't designed to carry that current for extended periods.

If you can solve that, with a properly rated input from the alternator when driving, then crack on.

If you already have a Bluetti AC200Max, then it would certainly come in useful, but it's not ideal for running a motorhome. The habitation electrics of a motorhome run from 12V: lights, water pump, fridge control board, heater control board etc. So you can park somewhere off-grid and still have lights, stay warm, cook a meal and have a chilled beer with no 240V hookup. The main heating power comes from diesel (for the Eberspacher heater) or LPG gas, controlled by a 12V control board. Similar for the fridge if it's a 3-way type, but 12V compressor fridges working just on 12V are getting more popular.

There was a solution for an Ecoflow power station mentioned on another thread. It's a B2B that charges from the alternator at 800W, equivalent to 67A at 12V. I wasn't impressed with the Bluetti offering, it only seemed to manage about 200W. But maybe they will all start to bring out a nice powerful B2B. That would make a difference, I think.
