This wiring diagram calls for an isolated DC-DC Charger. I have 2 Victron Orion-Tr Smart 12/12-Volt 360W DC-DC Chargers, non-isolated. Will they still work with this design?

I thought you had a 4, 300 watt each panel array using a 2000 watt inverter diagram but can't find it again. Please help

Hey Nate. Great tutorials. I’m going to buy your wiring diagram I believe for the 300-600 ah as I want to make sure I have enough power down the road. My question is how do you figure out what size system is right without going way overboard? I do understand it’s adding up all my electrical loads I will be putting in. I’m looking at a water heater, 2 burner induction cooktop,12 volt frig, webasto heater, on board compressor, airmaxx fan, possible AC unit in the future, and lighting and convenience 12 volt and 120v outlets.

I am an electrician by trade but never in the solar and dc to ac conversation so I do have a fair amount of knowledge. I figured since you have it dialed in, why reinvent the wheel.

I do plan on using all victron components with battle born and the 4 panel system by renogy. I do like the idea of the Bluetooth connected device to monitor the system so running the gauge for reading the status I’d like to leave out if possible.

I do have all your products in my Amazon list for when I do start. Thanks for that.

Anyway thanks again

If this is a portable generator, you would just plug your shore power cord into the generator instead of the shore power pedestal.
