6KW GROWATT 48VDC OFF-GRID SOLAR INVERTER SPF6000ES PLUS + FREE Wifi Dongle

Growatt SPF 6000 ES Plus 6kW 48V Off-Grid Inverter (Hybrid)

The Growatt SPF 6000 ES Plus is a 6kW off-grid inverter designed for homes and small businesses that want reliable backup power and flexible solar integration. It combines inverter and solar charging in one unit, with dual MPPTs to harvest more energy from your PV array and smarter controls to manage when you charge batteries and when you power loads.

Built for real-world backup scenarios, it supports both grid and generator AC inputs (with an integrated transfer switch) so you can keep running through outages and recharge batteries when solar is limited. It also supports system expansion by running up to 6 units in parallel when you need more capacity.
