What to look for when choosing an inverter generator?

When choosing an inverter-type power plant, you should consider a number of important points:

• Power. This parameter depends on the value of the total power of the equipment connected to the generator. For backup and power supply of low-power household appliances, a 1-4 kW station is sufficient. Connecting power tools, pumps and other productive devices requires a 5-7 kW generator.
• Launch. Inverter generators can be equipped with either a manual or electric starter. The manual version requires physical effort when starting. The electrical system means starting the equipment at the touch of a button. Many generators also support automatic starting.
• Generator type. The industry produces synchronous and asynchronous generators. The former withstand overloads well and are suitable for powering equipment with high inrush currents. Asynchronous models cope well with short circuits and are suitable for heating devices.
• Number of phases. Single-phase generators are designed to power equipment that requires a standard voltage of 220 V - these are household appliances, tools, lighting. Three-phase models are used to provide energy to devices with appropriate connections - pumps, welding machines and others.
• Manufacturers of generators. Inverter stations with excellent technical characteristics, contrary to popular belief, are produced not only by foreign, but also by domestic companies. The most popular models today are models from the Fubag, PATRIOT, Huter, CALIBR, and Daewoo brands.

How are inverter generators different from conventional generators?

An inverter generator converts alternating voltage into direct current, passes it through filter capacitors and inverts it back .

Reference! Such a complex conversion circuit, unlike a conventional one, allows you to obtain a more stable electrical voltage at the output and safely connect sensitive electronics to the station.

Additional advantages of inverter generators are economical fuel consumption, compact size, lighter weight and low noise level.

Work principles

In terms of its performance characteristics, this generator is similar to a simple gasoline generator. However, there is a significant difference: the current does not reach the output directly from the current collectors, but undergoes a double conversion. As a result, a sinusoid of ideal shape is formed with equalized characteristics of force and standard voltage.

Operating principle of the inverter

Thanks to these operating principles, inverter gas generators provide devices with current with stable characteristics, which significantly increases the service life of sensitive high-precision equipment.

Equipment design

A portable inverter-type station is based on the operation of a special unit, which consists of:

• Converter;
• Rectifier;
• Microprocessor.

The function of the rectifier is to convert alternating current into direct current.

Next, using special filters, the constant oscillation frequency is again converted into a variable frequency and supplied to the connected equipment. As a result of the operation of the inverter gas generator, uninterrupted operation of any high-precision equipment is ensured, and lighting fixtures will not flicker.

IV. Maintenance and cost of ownership

Generators require an oil change every 25-50 hours of operation or every 3 months; less often the filter and spark plugs need to be replaced. It is necessary to have fuel reserves and monitor its level. The starting battery is changed once a year. Good gas generators and stationary diesel power plants are always installed with the conclusion of a service agreement (20-40 rubles). The lifespan of budget generators is 3-4 years, expensive ones – up to 10 years. Generators installed outdoors require crankcase and battery heating in winter. The price of fuel for one hour of work is from 35 (gas/diesel) to 120 rubles (gasoline).

Inverters practically do not require maintenance (only in the case of very dusty rooms), on-line UPSs, due to the through-cooling circuit, are preferably cleaned of dust every 1-2 years (remove the housing and vacuum), the conversion efficiency is about 90%. Batteries are changed every 8-12 years depending on operating conditions. One hour of work ~5 rubles (charge cost).
