Electric generator GRAPHITE 58G904 — portable mains-powered generator, model 58G904

GRAPHITE 58G904 is a portable mains-powered electric generator designed to supply temporary or backup electricity where grid power is unavailable or unstable. With a rated output of 2.0 kW and a maximum output of 2.2 kW, the unit is driven by a four-stroke gasoline engine delivering 4.8 kW (6.5 hp) and features a 15-litre fuel tank. The generator includes an AVR voltage regulator to stabilise output voltage, overcurrent protection and a protective frame. It starts with a practical recoil starter cord and provides a combination of AC and DC outputs for powering a range of equipment on sites, farms, workshops or during outdoor events.

Advantages

The unit’s AVR system ensures stable voltage for connected devices while integrated overload and overcurrent protections reduce risk to both the generator and attached equipment. A EURO V compliant engine reduces emissions compared with older designs. Compatibility with common gasoline grades (92, 95, 98) and use of SAE 15W-30 oil simplify refuelling and maintenance. Compact dimensions and a weight of 41 kg make the generator portable enough for temporary installations yet sturdy thanks to its protective rack.

Suitable for

• Temporary power supply on construction sites and workshops
• Outdoor events, fairs and market stalls
• Emergency home backup for essential appliances
• Powering small farm equipment and tools

How to use

Before starting, fill the fuel tank with the recommended gasoline grade (92, 95 or 98) and check engine oil level using SAE 15W-30 oil. Verify that connected appliances do not exceed the generator’s rated or maximum power. Place the generator on a stable, level surface with adequate ventilation and keep it away from flammable materials. Start the engine using the recoil starter cord and allow it to warm up briefly before connecting electrical loads. Connect devices to the 230 V sockets or the 12 V outlet as required and monitor the load and fuel level during operation. Shut down connected equipment before turning off the generator and follow cool-down procedures before refuelling.

Usage recommendations

Maintain the generator regularly: check and replace engine oil at the intervals recommended by the engine manufacturer, inspect and clean or replace the air filter and spark plug (F6RTC) as needed, and drain fuel if storing the unit long-term. Operate the generator outdoors or in well-ventilated areas to avoid carbon monoxide buildup, observe local noise and emissions regulations, and use appropriate extension cords and protective devices when powering sensitive electronics.
