Battery storage
Solar during the day. Stored energy when you need it.
A battery turns your solar system from a daytime bill-saver into an around-the-clock power supply — including when the grid goes down.

Why add a battery
Load-shedding shouldn't set your schedule.
Backup during outages
When the grid drops, your battery takes over in moments. Essential loads keep running.
Nighttime energy usage
Use the sunlight you captured at noon to power your evening. Solar stops at sunset; your system doesn’t.
Better solar utilization
Without storage, surplus solar can go unused. A battery captures it instead.
Energy independence
Buy less from the grid and rely more on power you generated yourself.
Backup duration depends on battery capacity and the loads you run. The calculator gives a first estimate; a real design confirms it from your actual loads.
The technology
Why LiFePO4 has won.
Long cycle life
LiFePO4 chemistry is designed for thousands of charge cycles — built for daily use, not occasional backup.
Safer chemistry
Lithium iron phosphate is among the most thermally stable lithium chemistries in wide use.
Compact and clean
Wall-mounted, maintenance-free and quiet — a different world from lead-acid banks.
Smart by default
A battery management system watches every cell, and a decent system shows the state of charge live in an app.
