So we are building out a 48v system for our fifthwheel system to be off grid and boondock a lot. We currently have 2 48v quattros, 5000/70 that setup on my mock up board in the shop. The plans is to mock it all up and then transfer it over to the existing basement wall space. I recently picked up two more quattros (all the same hardware rev) with the idea of maybe adding the two extra quattros to the house or even to the trailer. So my question is this. I know I can configure the existing quattros in split phase or just parallel. Could I mount 4 quattros in the trailer and then set the batch up in split phase?
