Growatt SPF 5000ES 5kW 48V Off-Grid Inverter

The Growatt SPF 5000ES is a 5 kW, 48 V off-grid inverter that combines a pure sine wave inverter, a 100 A MPPT solar charge controller, and a UPS function in one unit. It suits homes, shops, and small offices running on solar and batteries, with the grid or a generator as backup.

It works with both lithium and lead-acid batteries, delivers up to 10 kVA of surge power for starting motors such as pumps and fridges, and peaks at 93% efficiency. Up to six units can run in parallel for bigger loads or three-phase supplies.

As an off-grid inverter, it doesn't export power to the grid, which keeps installation simple on sites where export isn't allowed.

We size the inverter, battery bank, and solar array to your actual loads and backup hours, and handle the installation, earthing, and surge protection.
