Battery backup (BESS)

A BESS stores the solar your panels make in the day in lithium batteries. You then use that power at night and right through long outages, silently, with no generator. Paired with a hybrid inverter, it gives a Karachi home full power independence instead of leaning on the grid and its rising rates.

It depends on your evening and night-time use. We add up the appliances you want to run and for how long, then size the lithium storage to match. A whole-home backup usually uses a larger or expandable battery bank. You will see the exact capacity in kWh and the expected runtime in your quote, sized to your home, never a generic package.

Yes, when it is sized correctly. We match the inverter and battery bank to your peak load and the runtime you want, so ACs, fridge, fans and lights keep running through load-shedding. Heavier loads need more inverter capacity and storage, so we work this out at the survey to make sure nothing trips.

We use LiFePO4 lithium batteries, rated for thousands of charge cycles, typically 8 to 12 years or more in Karachi's climate, with no maintenance. Each battery carries a manufacturer warranty, with the term listed in your quote. Lithium also handles heat far better than older lead-acid or tubular batteries.

Increasingly, yes. Grid tariffs keep rising, and under Pakistan's new net-billing rules you earn only about Rs 11 for each unit you export, far less than you pay to buy it back at night. Storing your own day-time solar lets you use it in the evening at no extra cost, while also giving you full backup. Most battery systems pay back in 3 to 5 years.

Yes. Our battery systems are modular. You can add more lithium packs over time as your use grows or your budget allows, with no need to replace the inverter or rewire. We design the install so expansion is a simple add-on.
