The Core Components
You will need to source four main items from a local hardware or electronics store:
1. A 12V Lithium Iron Phosphate (LiFePO4) Battery (50Ah to 100Ah is ideal).
2. A Pure Sine Wave Inverter (1000W is usually sufficient for small electronics).
3. An MPPT Solar Charge Controller (20A to 30A).
4. A single 200W to 300W Solar Panel.

The Assembly
First, secure the battery inside a heavy-duty plastic toolbox or cooler. Connect the battery terminals directly to the Inverter using thick gauge wire (e.g., 4 AWG) and an inline DC breaker or fuse for safety. Next, connect the battery terminals to the battery side of the MPPT Charge Controller.
Adding the Solar Panel
Finally, run MC4 cables from your solar panel into the PV side of the MPPT Charge Controller. When the sun shines, the controller will safely charge the battery. When the JPS grid fails, simply plug your extension cord into the inverter, flip the switch, and you have instant, silent power.
