[QUOTE="boltonsparky, post: 500009, member: 4678"] Thanks Andy. I know some inverters don't like the earth and neutral connected together so we will be trying to find one that it is possible on. I'll be honest inverters fry my brain and I've been trying to work out potential faults that could arise and then the fault paths to try and get my head round if they are dangerous in certain faults or not. Then there are types that aren't isolated from the negative on the battery side so could potentially send the van body live but if there isn't a connection on the AC side to the body because the earth and neutral aren't linked nothing will trip off, or that's how I understand it. I've even seen pictures of people earth spiking their inverters into the ground which to me seems totally pointless as there is no reference to the actual earth anyway. In this one most things are 12v, the TV for example is 12v and just connects straight to the battery 12v system. It's only for the microwave and the odd plug in appliance the inverter is used but to just have one socket for the inverter would mean unplugging from the mains sockets, and running an extension across the van to an inverter socket so makes more sense to connect the inverter to the van's existing AC system.
