About this product

What it is, and what it is for

The GSL Energy 51.2V 280Ah 14.34kWh LiFePO₄ Battery is a high-performance, outdoor-rated energy storage solution designed for residential, commercial, and light industrial ESS applications. Built with safe lithium iron phosphate (LFP) chemistry, this battery delivers exceptional cycle life, intelligent energy management, and reliable performance in demanding environments.

Featuring an IP65-rated enclosure, the battery is suitable for ground or outdoor installation, offering protection against dust, rain, and harsh weather conditions. Each unit integrates an independent smart BMS that actively manages charging, discharging, temperature, and system protection to ensure safe and efficient operation.

With 14.34kWh usable energy per module and support for up to 16 batteries in parallel (229kWh total), the GSL Energy battery system is highly scalable. It is compatible with most major hybrid inverters via CAN 2.0 and RS485 communication, and includes WiFi and Bluetooth monitoring for real-time system visibility.

Designed for long service life, the battery supports over 8,500 cycles at 80% depth of discharge, making it an ideal choice for solar self-consumption, backup power, and off-grid or hybrid energy systems. The product is backed by a 15-year warranty and globally recognized safety certifications.

Common questions

Before you order.

If yours isn't here, ask an engineer. It costs nothing and it's the step most people skip.

What if I'm not sure this is the right product?

Ask before you order. Send us what you need to run, or your pool or well figures, and an engineer will confirm the choice — it costs nothing. Or use the finder below, which sizes from what you actually run and shows its reasoning.
