Battery energy storage capacity is the total amount of energy the battery can store, measured in kilowatt-hours (kWh) or megawatt-hours (MWh). Think of this as like the size of a water tank where you measure the water capacity in litres.
The capacity of a home battery is expressed in kilowatt hours (kWh). This represents the amount of power the battery can store. For example, if you use a 1.000 watt (1 kW) device and let it run for one hour, you have used 1 kWh. Please note: some manufacturers state the gross capacity, while in practice you can only use the net capacity.
Some batteries offer just 3–5 kW of power—enough for lights, a fridge, and a few other essentials. Quality home battery systems are modular, which means that you can scale both energy storage capacity and output power based on your needs.
TLDR: As a minimum, aim for battery storage equal to 25% of your daily usage, plus 2 kWh for backup. So if you use 20 kWh a day, don’t go smaller than a 7 kWh battery. It probably won’t last all night, but it’ll usually cover the expensive evening peak. How Much Battery Storage Do You Need? It depends what you want your solar battery to do.
