Battery Storage

Store your excess solar energy

Having battery storage are an important component of your solar system, particularly in grid-connected situations. Store any surplus solar power you generate for use at any time.

All of our systems come with 24/7 online monitoring. See in real-time the amount of your PV generation, your energy consumption, your battery storage (SoC State of Charge) and to set your preferences to optimize for energy independence and savings. And better still it’s free!

How can batteries support my solar system?

Whether you’re looking at reducing your power bill or eliminating it entirely, solar power with battery storage backup is the optimal solution.

Having a battery back up system allows you to go even further by storing surplus solar generation for use at any time. If you are still connected to the grid and your home experiences power cuts or regular power outages, then having a battery to back up those essential loads would be the perfect solution, while protecting yourself against rising electricity prices from the power companies.

At Solartive we use the latest technology available and have different options from small tiny homes right up to big homes with big loads that need plenty of storage especially when there is a power cut.

If you’re unsure whether you should opt for a battery storage system, our local team can talk this through with you. Just get in touch!
