I'm giving up full-time RVing I have a Multi plus II 12v inverter, 2 Battle Born game changers. 1200 Watts of PV. Probably adding more, Once I figure out if I need permits or if I'm even allowed to install it on my new house (brick built in 1914) I want to put the PV panels on the garage and run the PV lines to.the house, it gets to cold in the Michigan UP for the Lifepo4 batteries to be in the garage. I want to dedicate some power to the Hot water furnace (only a small pump for water and a controller) the Internet and some lights. Should I buy a Quotro or can I us the Multi plus II? The house has 100a service I'm thinking of upgrading to 200a in a few years. My biggest question is what do I need to use the ESS so it uses the PV power before the Grid power? I've been searching for information to do this in the camper but I can't find any tutorials? I've been turning down the Amp draw to the lowest the Cerbo GX will allow to use more PV than grid. Now that I am hopefully moving to a house I don't want it to be a Big UPS backup using Grid before PV. Any ideas where to find the information I need?
