The Sumec Firman 5.0KVA Keystart Generator (ECO7990ES) is a powerhouse of reliability designed for the modern Nigerian home and office. Part of the premium "Ecological" series, the ECO7990ES is engineered to provide high power output with optimized fuel efficiency, making it a strategic choice in 2026's high-petrol-price economy.
Despite the "7990" model number, this unit is a True 5.0KVA rated machine, providing the honest power needed to run heavy inductive loads without the voltage drops common in generic brands.
Key Features & 2026 Performance Standards
The ECO7990ES is built to survive the incessant grid failures of urban life while protecting your expensive digital investments.
- 100% Pure Copper Alternator: Heat is the primary cause of generator failure. The ECO7990ES uses thick-gauge copper windings that handle the stress of 10+ hour runtimes far better than aluminum alternatives, shielding you from the annual capital cost of frequent repairs.
- Massive 28.5L Fuel Tank: In 2026, convenience is king. This oversized tank allows the generator to run for up to 11.5 hours at 50% load. You can power your household through the night and into the next morning on a single fill.
- Electric Key Start: The reliable 12V electric starting system ensures that restoring power is as simple as turning a key. It also retains a manual recoil as a dependable backup.
- Industrial SPE390E Engine: Powered by a 13.0HP 4-stroke OHV engine, the ECO7990ES provides the high torque necessary to start air conditioners and pumping machines effortlessly.
- Smart AVR (Automatic Voltage Regulator): To protect your mobile phones, laptops, and 4K Smart TVs, the built-in AVR stabilizes voltage output, preventing the "dirty power" spikes that damage sensitive circuitry.
Load Profile: What Can the ECO7990ES Power?
This generator is the "Master of the House" for a large 3-bedroom apartment or a standard office. It comfortably supports:
- Air Conditioning: One 1.5HP Inverter AC or one 1.0HP standard AC alongside other essentials.
- Water Pumping: Effortlessly powers a 1.0HP water pump (Sumo).
- Kitchen & Food: Large double-door refrigerators and deep freezers.
- Entertainment: Multiple LED TVs, home theaters, and gaming consoles.
- Productivity: WiFi routers, server racks, and multiple mobile phone charging stations.
