Product Summary:
The Growatt 3kW SPF 3000TL LVM-ES Stackable Off-Grid Inverter is a compact, all-in-one solution designed for off-grid, backup, and small-scale energy systems. Delivering 3,000W of pure sine-wave output with support for up to 4,000W PV input, it provides reliable, efficient power for cabins, small homes, RVs, and portable energy setups.
This multifunctional unit integrates a high-frequency inverter, MPPT solar charge controller, and UPS module into one streamlined system – reducing installation complexity and cost. With a wide MPPT range of 120 – 250VDC, it enables longer solar string runs and simplified system design without the need for combiner boxes.
Designed to pair specifically with 48V HUSKY INV batteries, this inverter supports seamless communication and optimized performance for compact off-grid systems. With optional WiFi/GPRS monitoring, users can track system performance remotely for improved control and visibility.
