About this item
The 48V 2× HUSKY 2 INV + Growatt 3kW Inverter Kit is a high-capacity, compact energy solution designed for off-grid, backup, and small-scale power systems. Combining two 48V 5.12kWh HUSKY 2 LiFePO₄ INV batteries (10.24kWh total) with the reliable Growatt 3kW inverter/charger, this system delivers efficient, scalable power for cabins, RVs, small homes, and portable energy setups.
The Growatt inverter provides 3,000W of pure sine-wave output with support for up to 4,000W PV input, integrating a built-in MPPT charge controller, inverter, and UPS module into one streamlined unit. Its wide 120 – 250V MPPT range allows for simplified solar installation with longer string runs and fewer components.
Paired with HUSKY 2 INV batteries – featuring inverter communication capability, Tier 1 LiFePO₄ cells, advanced BMS protection, and self-heating functionality – this system ensures stable, long-lasting performance in demanding environments. The batteries’ IP65-rated, vibration-resistant enclosures make them ideal for rugged indoor or outdoor installations.
