Hi . I have a simple System in a Camper Van. A Phoenix 12/250 mainly for charging a laptop; Also running a Blue Smart 12/17 mains charger. I only want one Socket in the Camper. So inverter connected but if I want to hook up to mains power at a campsite how do I wire this ? The manual warns against connecting another ac source to the inverter. Is there a way I can have a hassle free way of just connecting to mains without disconnecting the inverter. Thanks for any advice.
