16kWh solar battery
A 16kWh battery can suit smaller families with modest evening electricity use and minimal EV charging.
- Small families
- Everyday household appliances
- Minimal EV charging
- Moderate backup requirements
Take advantage of the power you generate
Without a battery, the solar you don't use during the day may be exported for around 2 cents per kWh.
Some systems earn nothing at all. That power can then be bought back after dark at 10 to 15 times the export rate. A battery closes that gap. It holds your daytime surplus and hands it back in the evening, when power costs the most, so more of what your panels make actually stays in your pocket.
How a battery works through the day
Your panels generate through the daylight hours, usually more than the house uses while everyone's out.
That surplus charges the battery instead of being exported. Once the sun drops and generation falls away, the battery discharges back into your home, so you run on your own stored power before you touch the grid at all. More of your solar used by you, and a noticeably smaller bill at the end of the quarter.
What a battery actually gives you
Your panels generate through the daylight hours, usually more than the house uses while everyone's out. That surplus charges the battery instead of being exported, giving you full control over your own power.

A hedge against the next round of price rises
For a lot of households, it's the piece that finally makes solar feel like it's fully paying off.
