Description

A Felicity 12 kWh power unit for homes and small businesses needing stored energy. It sits in our power inverters range and is sized for loads in the region of a 3-bedroom family home running lights, fans, a fridge, a freezer, a television and a washing machine.

Twelve kilowatt-hours of storage is a substantial reserve — it is roughly a full day of running for that household, or a shorter reserve paired with a larger array. How much you actually need comes down to two numbers: your daily consumption in kWh, and how many days you want to carry without the grid.

Both come out of our complete solar sizing guide, which also covers continuous versus surge inverter ratings — the detail that decides whether your fridge and water pump can start at the same time.

Confirm the battery bank voltage before ordering. Units like this are commonly 48V, and the voltage has to match your inverter, charge controller and cable sizing. Our 24V versus 48V guide explains why that one decision drives your cable cost and your expansion options.
