What it is, and what it is for
The GSL Energy 14.34kWh 51.2V 280Ah LiFePO₄ Battery (model GSL051280A-B-GBP2F) provides modular energy storage for residential solar, backup power, and hybrid energy systems. Each module combines lithium iron phosphate cells with an independent battery management system (BMS) to manage power output.
Its IP65-rated enclosure supports ground and outdoor installation. Connect up to 16 modules in parallel for a manufacturer-rated 229kWh of nominal storage. The manufacturer states compatibility with most available hybrid inverters; confirm compatibility with your specific inverter before installation.

Depth-of-discharge note: The datasheet lists 11.47kWh discharge energy at 80% DoD and separately lists 90% as the recommended depth of discharge. These are distinct specifications; 11.47kWh is the published energy value used below.
Battery package capacity
| Modules | Nominal energy (kWh) | Discharge energy at 80% DoD (kWh) |
|---|---|---|
| 1 | 14.34 | 11.47 |
| 2 | 28.68 | 22.94 |
| 3 | 43.02 | 34.41 |
| 4 | 57.36 | 45.88 |
| 5 | 71.70 | 57.35 |
| 6 | 86.04 | 68.82 |
Package values are calculated by multiplying the datasheet’s rounded per-module ratings by the module count. These are battery-side energy values before inverter losses; actual delivered energy depends on operating conditions and system configuration.

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.
