Overview

The Sumec Firman SPG3800E2 is a portable petrol generator rated at 3.5kVA (rated output 2.8kW at 50Hz / 3.1kW at 60Hz). It combines a single-cylinder 4-stroke air-cooled OHV engine with an AVR-equipped alternator for steadier voltage under varying loads.

With a 25 L fuel tank and long run time at three-quarter load, this unit is suited to sustained backup for fridges, freezers, lights, fans, TVs, laptop chargers, small shop equipment and office essentials during frequent grid outages. It also includes electric start plus recoil as a backup.

Built with a brush alternator wound with copper enamelled wire, it offers basic protection and useful accessories such as a voltmeter, fuel meter and AC circuit breaker. Wheels and a 12V DC output are available options depending on configuration.
