My house is originally on grid and I am moving to off grid. I am doing this in phases. I now have the following system implemented which is supplying power to almost 1/2 of my house circuits (via a transfer switch):
2.5 kW PV array
VICTRON ENERGY SMART SOLAR MPPT CHARGE CONTROLLER 150V 60A
48V battery bank consisting of (4) KiloVault 12V, 300Ah batteries wired in series
QUATTRO 5000W 48V INV/CHARGER 120VAC
I want to add another circuit to this setup supplying power to a 240V house circuit (for a cistern pump).
I found a Victron reference diagram here:
I'm just looking for validation that I'm on the right track here. If I add an Autotransformer and wire it as shown, is this going to give me the 240V split phase that I need for my 240V circuit (I'm in the US)
WRT loads, relative to the rest of the 120V circuits the 240V circuit uses very little power.
Thanks for any feedback that is offered.
FWIW, I love the Victron products and their software. I'm using a Cerbo GX as my communications hub and I love being able to view a snapshot of the system on the VRM portal and well as to have a history of the data that has been collected.
