Product Description

The Growatt SPF 3000TL LVM-ES is a compact all-in-one off-grid inverter that combines a 3,000W pure sine-wave inverter, MPPT solar charge controller and UPS transfer switch in one unit, reducing installation complexity and cost for cabins, small homes, RVs and backup systems.

It accepts up to 4,000W of PV with a wide 120–250V DC MPPT range for longer string runs, charges batteries at up to 80A from solar, and parallels up to 6 units for 18kW of capacity or split-phase / three-phase output. This version is configured for closed-loop communication with BigBattery 48V HUSKY 2 INV batteries.
