Overview

The Sumec Firman SPG3800 is a compact 3.1kVA petrol generator built for everyday backup power. Its single-phase alternator and 4-stroke SFE270 engine deliver stable 220V output for lights, fans, TVs, refrigerators and small workshop equipment.

Designed as a portable unit with a recoil start, the SPG3800 balances petrol efficiency and usable power. A 25 L fuel tank keeps runtime reasonable between refills, while the 12V DC outlet supports battery charging or small DC loads.
