I currently have an ark power station that I want to run as a second battery in my caravan. Can I hook this up to my battery in the van using an Anderson plug to run these in parallel and then charge my van battery with my 160 watt solar panels. Would this then also charge the battery in the ark. I would then be using the van battery to run my lights etc and the ark to run my waeco fridge. Also do I have the isolator switch on whilst it is charging this way.
i see nothing wrong with your proposed set up the only thing that is important to be aware of is when you want the battery in the Ark Pak to be charged by your solar Panels you must always have your red isolator switch in the ON position for the battery in the Ark pak to charge up if you don't it will not charge so this is really important point to be aware of.
