Hiall!
I'm starting a design phase for my tiny house. The property is connected to the grid, but I decided to go for a solar setup.
I Am looking into following functionality for my solar setup:
- Solar to charge my batteries (bank of 2 LiFePO4), my electrical consumers will be 12V DC as much as possible.
- I will require tools to run off 220V, so the setup requires an inverter.
- When consuming 220V, the power should come from the batteries through the inverter, NOT from the grid.
- When batteries get empty, the power should switch to the grid and continue to run my 220V.
- Empty batteries should get charged from solar, NOT from the grid.
I Am currently eying following components:
Solar: 2x Polycrystalline Solar Panel 150W 12V (approx. 25 Amp.)
Batteries: 12V (pack of 2 LiFePO4, parallel)
Battery charging: Victron BlueSolar MPPT 150/35
DC/AC Inverter: Victron MultiPlus Compact 12/1600/70
My main question for now: If I'm not mistaken, the Victron MultiPlus Compact 12/1600/70 is almost always used to supply 220V as I require, but when batteries need charging, it will use the grid to charge. This is not desired by me: I want to establish priority to the solar panels for charging. Can this be done with the components I have listed?
Thanks in advance and have a great, SUNNY day!
Cheers, Igor
