Battery Energy Storage Solutions
Battery storage systems that save your solar energy, reduce high peak-hour electricity charges, and keep your power running around the clock — for homes, businesses, factories, and large-scale operators across India.

Remote Monitoring
Store Solar Power. Cut Peak Demand.
Never Face an Outage Again.
Without battery storage, your extra solar power just goes back to the grid at low rates — and you end up buying expensive power in the evening and at night. You still pay high peak-hour charges. Outages still disrupt your work. A battery storage system solves all of that.
We design and install complete battery storage systems — from small 5 kWh home setups to large 10+ MWh industrial and grid-scale systems. We choose the right battery type for your needs, connect it to your existing or new solar plant, and back every system with round-the-clock monitoring and a 15-year battery warranty.

Why Battery Energy Storage Changes Everything
Peak Demand Cost Reduction
Use your stored battery power during expensive peak hours. Most businesses and factories reduce their monthly peak charges by 30–60%.
24×7 Uninterrupted Power
Your power switches to battery backup in under 20 milliseconds during a grid failure — so critical equipment, servers, and production lines keep running without any break.
Maximise Your Solar ROI
Store your extra daytime solar energy and use it in the evening and at night — so you rely less on the grid and recover your investment in 4–6 years.
Grid Support & Ancillary Revenue
Large-scale battery systems can help regulate grid frequency and take part in energy market programs — earning extra revenue on top of your energy savings.
Equipment & Process Protection
Keep sensitive industrial equipment and production lines safe from grid voltage fluctuations and sudden power interruptions.
