What we build
One system, sized to your site
Pick the kind of site. This is what we would put there, what it does through the day, and what it earns from.
Factories and offices
Battery and inverter in one cabinet, sized to the site's load and the outages it sees.
Earns from
- Evening peak avoided
- Diesel avoided
- Solar used on site
Through the day
- Solar hoursCharges from the roof, or from the grid at the cheapest rate of the day.
- Evening peakRuns the site on stored power instead of peak tariff.
- OutageTakes over in an instant. Nobody notices.
- NightHolds a reserve for the morning.
Inside every system
- 01
Battery and inverter
One cabinet. Cells we match ourselves, lot by lot: lithium iron phosphate today, sodium-ion in development. Cooling sized for 45-50 °C.
- 02
Our board
Every cell's voltage and temperature, reported live. We see a fault coming and fix it before it costs you a day.
- 03
Our software
Decides when to charge, when to run and when to hold, from your tariff, your roof and the state of the cells.
Run by us

Tell us about the site
A bill, the backup load and how often the grid goes.

We size and install
The cabinet, the wiring and the switchover, on your site.
- 03
We run it
Every day, from the tariff and the state of the cells. Service before a fault, not after.

You read the statement
What it earned this month, line by line, and how it is.
Built for heat, built to be safe
- Cooling sized for 45-50 °C, with proportional control, not on and off.
- Two-fault-tolerant design, off-gas detection and suppression in every system.
- Designed for India's BESS safety rules that apply from April 2027.
Our lab turns bought cells into known cells
- 01
Incoming checks
Every cell: voltage, AC resistance, weight and size, then a two-week self-discharge hold.
- 02
Curve-based grading
Charge and discharge curves feed our sorting algorithm, which groups cells into near-identical sets.
- 03
Ageing in Indian heat
Samples from each lot aged at 0, 25 and 45 °C.
- 04
Sodium-ion
We are developing sodium-ion cells alongside lithium, on the same bench, for the same cabinet.

Start with your site.
Upload a bill and see what a battery would earn there, or tell us your backup load, how many hours a day the grid is down, and your tariff.
Meter reads a bill in your browser and shows what solar and a battery would do. Or email us a photo of the bill, and we reply with what a battery at your site would save and where the number comes from.
