Overview

The Sumec Firman SDG15000SE is a soundproof diesel generator rated at 12kVA with electric (key) start. Its silent canopy and brush alternator with enameled copper windings aim to reduce noise and deliver steady power for essential loads.

With a 25‑litre fuel tank and an approximate 6.4 hours runtime at 50% load, this unit is built for overnight outages and extended use without constant refuelling. The generator’s construction and listed oil capacity support regular maintenance for dependable performance.

Noise at 7 metres is specified, so it is more suitable for residential and commercial locations where neighbour disturbance is a concern compared with open-frame sets.

Why diesel?

Diesel engines use less fuel per hour under load and are built for long daily running — the usual choice for offices, estates and anything above 10 kVA.

How do I start it?

With the key — electric start, no pull cord. The starter battery should be charged; the generator keeps it topped up while running.

Is it quiet?

It sits in a soundproof canopy, so it is much quieter than an open-frame set — well suited to estates and offices. Place it outdoors on a level base with free airflow.

Is it brand-new and genuine?

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

What does the warranty cover?

12 months from delivery against manufacturing defects — engine, alternator, AVR, control panel and starter. We repair or replace. See Warranty & service.
