Battery storage that saves solar energy for the evening and for backup during outages.
A battery energy storage system stores surplus solar energy so it can be used later in the day or during power cuts. Modern lithium iron phosphate (LiFePO4) batteries offer deep usable capacity and long cycle life, while lead-acid batteries remain a lower-cost option for smaller systems.
We size storage according to the loads you want to support and for how long, and configure the inverter and charger for the selected battery type.
It depends on how much electricity you use, when you use it, and the space available. We review your electricity bills and loads during a site survey and size the system accordingly.
On-grid systems work with the utility supply and need no batteries. Off-grid systems run independently with batteries. Hybrid systems combine both, so they can keep essential loads running during power cuts. We recommend the right type after understanding your needs.
Yes. Panels still produce electricity on cloudy days, although output is lower than in full sunshine. Systems are sized with seasonal variation in mind.
Mainly regular cleaning of the panels to remove dust, and periodic inspection of connections, protection devices, inverters and batteries. We offer maintenance and inspection services.
