SOK Rack Batteries
High-performance LiFePO₄ storage for home, solar, and off-grid systems
SOK rack batteries are one of New Zealand's most trusted lithium energy storage options, combining premium LiFePO₄ technology with a durable, fully serviceable design. Engineered for both off-grid and on-grid applications, these modular rack batteries deliver reliable power, high usable capacity, and excellent long-term value.
Paired with Solagen's Energy Hub cabinet, SOK batteries create a complete, scalable energy system built for homes, tiny houses, workshops, remote sites, and commercial installations.

Designed for Off-Grid Living
SOK rack batteries handle deep daily cycling, winter load spikes, and seasonal temperature variations common in New Zealand installations. The lithium battery management system ensures clean, stable power delivery, while the serviceable aluminium casing provides added durability for long-term off-grid use.
When combined with Solagen's Energy Hub cabinet, you gain an integrated power solution with neat cable management, AC/DC protection, and intelligent battery-to-inverter communications for precise voltage control.
Modular 5 kWh Storage You Can Grow Over Time
Start with a single 5 kWh SOK battery or build a larger rack system exceeding 30 kWh. Expansion is simple — just add additional modules as your home, workshop, or off-grid setup grows. This makes SOK batteries ideal for solar upgrades, EV charging, and long-term energy independence.
The Perfect Match: Solagen Energy Hub
Our Energy Hub cabinet is designed specifically to pair with SOK rack batteries. It arrives pre-wired, pre-tested, and ready to install, with generator input options, Victron monitoring, and weather-resistant construction.
