Swapping out Multiplus 2 for a Quattro 2

Today we are swapping out our Multiplus 2 48/3000 for a Quattro 2 48/5000. Partially because its bigger. But most importantly we use the vans storage to supplement the house battery. Since the Multi only has a single input it means i have to reconfigure it each time we want to take it away and use the generator with it (it has ESS) and we dont want to back feed the generator after all
