Overview
The Sumec Firman RD8910E is a single-phase, 6.8kVA petrol generator built for sustained backup power. It pairs a 4-stroke, air-cooled 439 cc engine with a synchronous alternator and AVR to keep voltage stable under varying loads.
It offers both electric and recoil start and runs for several hours on its 25 L fuel tank — long enough to cover typical evening outages or daytime shop shifts. Expect robust construction with IP23 protection for basic weather resistance.
Key features
- Rated 6.8kVA output for household and small commercial loads
- Electric + recoil starting for convenience and backup
- 25 L fuel tank for multi-hour runtime at partial load
- AVR-equipped alternator for improved voltage regulation
- Designed for single-phase loads like fridges, lights, fans, TVs and shop equipment
What can it power?
Typical load estimate for 5.4 kW rated output, keeping a 20% safety margin (≈ 4,500 W usable). Motors (fridges, ACs, pumps) need extra power for a few seconds at start-up — that is already counted.
