India’s Trontek enters residential energy storage market with 1.4 kWh and 2.7 kWh lithium ion battery systems

Trontek has entered the residential energy storage market with the launch of Powercube 1.4 kWh and Powercube 2.7 kWh lithium-ion battery storage systems that support both solar and grid charging.

This marks a major strategic shift for Trontek, which is a battery partner for electric mobility (particularly e-rickshaws, two-wheelers, three-wheelers) and industrial power systems. The company said its Powercube systems are designed for both grid backup and hybrid solar usage, offering superior performance, higher storage efficiency, and significantly longer operating life than conventional lead-acid solutions.

The Powercube range is offered in both Standard and Premium models.

The Standard series includes the Powercube 1.4 kWh (12.8V/105 Ah) with a compact state-of-charge (SOC) indicator and the Powercube 2.7 kWh (25.6V/105 Ah) without an SOC display. Based on lithium ferro phosphate, the batteries last for 4000+ cycles, enabling multi-year reliability. Round-trip efficiency is >90%, significantly reducing energy losses.

The Premium 1.4+ kWh and 2.7+ kWh models feature an upgraded LED status display for enhanced user visibility and monitoring.

Samrath S Kochar, Founder & CEO, Trontek, said, “As rooftop solar expands, residential energy needs get more complex, and sustainability becomes mainstream, home-level storage will sit at the heart of our nation’s energy transition. By bringing our technology directly into households, across high-potential markets, we are helping accelerate India’s vision of a cleaner, more resilient and energy-independent future.”

Powercube 1.4 kWh and Powercube 2.7 kWh will be available through Trontek’s authorised distributor and channels.
