Product Summary:

The 48V HUSKY 2 INV + Growatt 3kW Inverter Kit is a compact, efficient energy solution designed for off-grid, backup, and small-scale power applications. Combining a 5.12kWh 48V HUSKY 2 LiFePO₄ INV battery with the reliable Growatt 3kW inverter/charger, this system delivers dependable, easy-to-install power for cabins, RVs, small homes, and portable energy setups.

 

The Growatt inverter provides 3,000W of pure sine-wave output with up to 4,000W PV input, integrating a built-in MPPT charge controller, inverter, and UPS module into one streamlined unit. With a wide 120 – 250V MPPT range, it simplifies solar installation by allowing longer string runs and fewer components.

 

Paired with the **HUSKY 2 INV battery – featuring inverter communication capability, Tier 1 LiFePO₄ cells, advanced BMS protection, and self-heating functionality – **this system ensures stable, long-lasting performance even in demanding environments. The battery’s IP65-rated, vibration-resistant enclosure makes it ideal for rugged indoor or outdoor use.
