Hyundai HY1000SI 4-Stroke Inverter Generator Details

Newly re-designed for 2016, with a smaller case and LED screen which displays the voltage, frequency and hour count. Produces a maximum output of 1000w / 1kW for powering appliances such as televisions, laptops, air compressors and more. Powered by an easy start 50cc 4-stroke Hyundai petrol engine, with a 230v socket and 12v DC battery charger. Compact, lightweight and portable, allowing you to store it in car boots or caravan cupboards, and carry it with ease.

This redesigned model has a slimmer case which allows you to store it in your car boot or caravan cupboard, as well as a molded handle which makes it easy to carry with a lightweight design of just 14kg. This smaller case is made possible due to the compact inverter board which is brand new for Hyundai inverter generators. It also features a full LED display which makes it easy to monitor the performance of the generator, including the voltage, frequency and hour count.

Powered by a 50cc 4-stroke easy start, recoil pull Hyundai petrol engine, the HY1000Si produces 1000w / 1kW and is more than capable of powering televisions, small air compressors for inflatable beds, electric heaters, laptops, lights, etc. The control panel features a 230v socket for use with any appliance which uses a standard 3-pin 13A UK mains plug, as well as a 12v DC battery charging outlet, so it’s ideal for a variety of uses. Producing a pure sinewave output, it can safely power all sensitive electronics without risk of damaging or overloading them.

This inverter generator is extremely popular for powering family holidays, and it’s built to be user-friendly with low maintenance requirements. Digital overload protection will shut the generator down should the load pass the maximum threshold, and low oil shutdown also turns off the generator should the oil levels drop too far.

Already an economical generator, the HY1000Si also has the added benefit of an “ECO” mode which, when selected, will lower the engine revs to match only the load being applied, which in turn increases the fuel economy, lowers the noise produced and extends the lifespan of the engine.

The hyundai HY1000Si can also be converted to be a dual fuel machine, running on both LPG as well as petrol, which is extremely convenient for caravan owners who will already keep a supply of LPG with them at all times.

Thanks to the inverter technology, the power out put is a pure sine wave, so there are no spike that cause damage to sensitive electronic equipment like computers and TVs.

No problems at all.
Clear instructions with the Hyundai HY1000SI 4-Stroke Inverter Generator.
I will use it to charge my LiPo batteries in the field for flying my RC planes and helicopters. My charger is sensitive and worked fine on the generator output.
Pretty quiet on ECO setting.
Four stroke = runs on plain unleaded petrol, nice and simple. (Posted on 17/01/2017)

Seems to work well however the fine mesh petrol filter restricts the flow when pouring in the fuel, I would recommend a small funnel to control this otherwise the fuel overflows the filler and runs down the control switches and power outlet. (Posted on 10/04/2016)
