With 400W of Solar and a 1.2KWh battery this setup with the right sun exposure can run a full sized refrigerator indefinitely. Wouldn’t hurt to do 2 panels instead of 1 to account for clouds but if you need something to keep the food fresh the next time the power goes out this could be your ticket.
Advantages
- Large enough battery to run some appliances indefinitely
- Lithium (LiFePo4) battery that should last 3000 cycles or more
- Will handle up to 720W of solar panels
Disadvantages
- Inverter is 1000 watts, could be undersized for running additional appliances.
- At 12 Volts if you are planning on a larger system in the future it will be harder to manage the wiring as it gets thicker to handle more load. 48 Volts is a sweet spot if you intend to run a cabin off solar as it brings the wire size down to a reasonable gauge.
Some of the pricing here is from other sites out of our control, with a single 395W Solar Panel expect this setup to cost about $1020. We are assuming the solar panel would be mobile and have not included any mounting hardware. Check out the RV build for some Z brackets that are heavy duty enough to handle these full size panels for installing on a roof such as your shed.
Beene Brothers strives to keep this in stock for $100 as a convenience. If we don’t have it available, Amazon and Aliexpress should be able to set up you with a unit.
This battery is put together by us here at Beene Brothers Solar. It is made up of brand new LiFePo4 Prismatic Lithium cells assembled with finger-screw battery terminals to make this portable battery easy to operate.
