Battery Storage

Smarter energy for your home

1. Use your own energy, day and night
A home battery lets you store the electricity your panels generate during the day and use it after dark. You’ll rely less on the grid, protect yourself from price rises, and make the most of every unit of renewable power you produce.
With built-in backup functionality, your home stays powered even during outages. Essential appliances can keep running while the rest of your neighbourhood goes dark, giving you peace of mind that your power is always secure.
Modern battery systems automatically charge when energy is cheapest and discharge when prices are high. This intelligent energy management means you’re always using power in the most efficient, and cost-effective, way possible.
Our battery systems are installed by certified professionals and built for longevity. Each comes backed by robust manufacturer warranties and 24/7 technical support, so you can enjoy dependable, worry-free performance for years to come.

FAQ

Frequently Asked Questions

Can I add a battery to my existing solar system?
Yes. Most existing solar setups can be upgraded with a compatible battery system. Our engineers will assess your current installation and recommend the best option.
Yes, many modern systems include backup capability. That means your battery can automatically power essential appliances during an outage, keeping your home running when the grid goes down.
No. You can install a battery on its own to store cheaper, off-peak electricity from the grid. Later, if you decide to add solar panels, your system can easily be integrated.
A typical lithium-ion home battery lasts between 10 and 15 years, depending on brand, capacity, and usage. All our systems come with manufacturer warranties and full technical support.
Storage capacity varies, but most domestic batteries hold between 5 kWh and 15 kWh — enough to power a home for several hours during the evening or overnight.
Yes. A well-sized battery helps you use more of your own solar power instead of exporting it to the grid. You’ll buy less electricity at peak prices and save more long-term.
Most domestic battery installations are completed in a single day, with minimal disruption to your home.
