Hi All,
We are building a camper van. I have a 200ah gel battery which has a recommended max charging current of 40A.
I want to add a 12|12 - 30 (alternator while driving) charger, but also have solar (100/30 MPPT) and also a 30A 220v charger. So each individually are fine, but if the camper is connected to 220V, the sun is out and I start the engine, I guess that adds up to 90A?
Any suggestions on how to make this a safe charging combination (other than: make sure only one is engaged at the time, because at some point you'll simply forget once).
Thanks!
Walter.
