Description
The Growatt SPE 12000 US is a multifunction hybrid solar inverter/charger designed for North American 120/240V split-phase systems. It combines a pure sine wave inverter, dual MPPT solar charge controllers, battery charging, and backup power switching in one unit.
Designed for both on & off-grid power, backup power, and solar self-consumption applications, it can integrate solar panels, a compatible battery bank, utility power, and a generator.
