Overview

The Sumec Firman SDG7000SE is a single-phase, soundproof diesel generator rated at 5.0kVA (maximum 5.5kVA). It uses an SDE186FAE 4-stroke single-cylinder OHV air-cooled engine and offers both electric and recoil starting for convenient use.

Built with a brush alternator and AVR, the unit provides a 12V DC output for battery charging and carries a 15L diesel tank for extended run times. At seven metres the measured noise is listed as 93dB, so placement away from sleeping areas or close neighbours is recommended.

This generator is suitable for household and small business backup: it can handle typical appliances such as fans, lighting, a TV, a deep freezer, a water pump and a small air conditioner when loads are managed carefully to avoid overload.

Why diesel?

Yes. Every Sumec Firman unit we sell is new, in the original manufacturer's box, with its manual and accessories.
