ES4000IER-EFI ENERGYSTORM INVERTER GENERATORS Digitial Power

The EnergyStar ES4000iER-EFi 4000W Digital Inverter Generator is a versatile and powerful solution for all your portable power needs. This generator is engineered with the latest digital technology to deliver reliable and efficient power, making it an ideal choice for camping trips, tailgate parties, construction sites, or emergency power outages.

The ES4000iER-EFi is a compact and lightweight generator, with a weight of just 99.2 lbs and dimensions of 21.2 x 17.2 x 12.3 inches. It features a robust and durable frame, designed to withstand the rigors of outdoor use. The generator is equipped with two 120V-240V 30A receptacles, one 120V 30A RV-compatible outlet, and one 12V DC outlet, providing ample power for various appliances and devices.

The generator's heart is a 208cc Subaru IN1100E engine, which delivers 4000 watts of surge power and 3500 watts of continuous power. The inverter technology ensures that the power produced is clean and stable, with a total harmonic distortion (THD) of less than 3%. This makes it suitable for powering sensitive electronics and appliances without causing damage.

The ES4000iER-EFi is equipped with a quiet muffler and a low-tone exhaust system, making it one of the quietest generators in its class. The noise level is just 58 dBA at 23 feet, which is similar to the sound level of a normal conversation. This makes it perfect for use in quiet camping sites or residential areas.

This generator features a Digital Multimeter, which provides real-time information about the generator's power output, frequency, and voltage. It also has an Eco Throttle mode, which adjusts engine speed based on the load, reducing fuel consumption and extending engine life. Additionally, it has a Fuel Efficiency Mode, which reduces fuel consumption by automatically adjusting engine speed to match the load.

The ES4000iER-EFi has a large fuel tank with a capacity of 4.2 gallons, providing up to 14.5 hours of runtime at 25% load. It also has a low-oil shut-off sensor and an automatic low-oil warning system, ensuring that the engine is always properly lubricated and protected.

The generator comes with various safety features, such as a circuit breaker to protect against overloads and short circuits, a low-oil shut-off sensor, and an automatic voltage regulator to maintain consistent voltage output. It also has a spark arrestor to prevent the spread of sparks and a CO Shield, which reduces CO emissions and provides a warning when CO levels become dangerous.

The ES4000iER-EFi is easy to transport, with a folding handle and wheel kit, making it easy to move around and load into a vehicle or trailer. It also comes with a one-year limited warranty and is backed by the support of Subaru's extensive dealer network. Overall, the EnergyStar ES4000iER-EFi 4000W Digital Inverter Generator is a reliable, efficient, and versatile power solution for all your portable power needs.
