Overview

The Sumec Firman SPS12000SE is a soundproof petrol generator rated at 5kVA (with a higher starting capability). It combines a silent canopy frame with a single‑cylinder air‑cooled engine to deliver steady AC power for common household and small commercial loads.

Designed for Nigerians dealing with frequent grid interruptions, this unit can run lights, fans, a TV, freezer, water pump and similar equipment when mains power drops. It offers both electric key/remote style start and recoil start for flexible operation.

Built with a brush alternator wound in copper and an AVR, the SPS12000SE aims to give stable output suitable for many domestic and small‑business devices. Its 20L fuel tank and multi‑hour runtime at partial load help reduce refuelling trips during extended outages.

What can it power?
