Battery storage
for your home
The sun shines during the day, but you use the most electricity in the morning and evening. A battery evens out that gap. It stores the surplus from your solar panels so you can use it when you really need it.

WHY HOME STORAGE
Why have home battery storage
Solar energy after dark
Whatever your solar panels make during the day, the battery stores. Instead of selling the surplus to the grid for a fraction of its value, you use it in the evening when you actually need it.
You pay less, and change nothing
The battery charges when electricity is cheap and discharges when it is expensive. The system does it automatically, without you switching supplier or watching tariffs.
Power even during an outage
When the grid goes down, the battery takes over powering the house automatically. Lights, fridge and other appliances keep running.
MAKING THE MOST OF SOLAR
Energy that does not go to waste
Panels produce the most while you are at work. In the evening, when you actually need the energy, production drops to zero. Battery storage solves that mismatch and lets you draw on your own reserves whenever you want.
RECOMMENDED
MorningMiddayEvening
Bought from the gridSolar used directlyEnergy produced
Morning - low production, high demand
The panels are not producing enough yet, but demand is high. You make up the difference from the grid at full price.
Midday - high production, low demand
The panels run at full output while the house is empty. You sell the surplus to the grid for a fraction of its value.
Evening - low production, high demand
Production has dropped to zero and demand is rising. You buy from the grid all evening.

What is battery storage for? Is it worth it without solar? What if it breaks? Here you will find the answers most people look for before deciding.
It stores the electricity your solar panels produce during the day so you can use it in the evening or at night. Without storage, the surplus goes to the grid, usually for a low feed-in price.
