Overview

The Sumec Firman SPG8000E2 is a petrol-powered portable generator rated at 5 kVA (with higher starting capacity). It pairs a single-cylinder SFE390E engine with a brush alternator wound in enamelled copper to deliver stable single-phase 220V power.

It offers both electric and recoil starting, a 25 L fuel tank for extended run time, and a 12V DC charging output. The unit includes handle and wheel kit for easier movement and a built-in battery for electric start.

Designed for everyday backup, this generator can supply refrigerators, freezers, lights, fans, TVs, laptops, POS terminals and light workshop tools during frequent power interruptions.

What can it power?
