Gasoline generator with autostart: TOP-13 best single-phase and three-phase models, as well as with built-in automatic transfer switch

Problems with unstable centralized power supply are solved by purchasing a generator. The equipment is presented on the market in three versions - with manual start, electric starter, and automatic start.

Manual and electric devices are much cheaper in price, but the latter are easy to use.

They differ in design, including a fuel generator (engine, tank, rotor and other elements) and an automatic transfer switch (control unit, mechanism for switching the central power supply to an autonomous one).

The main advantage of generators with automatic transfer switch is instantaneous switching on in the absence of current in the general network.

The article provides an overview of the best models with autostart, based on owner reviews.

How to choose and what to pay attention to?

The recommendations are as follows:

Decide on the type of power plant . There are petrol, diesel and gas. Gasoline generators are attractive due to their compact size, low noise level, trouble-free operation at low temperatures, and a wide power range. Diesel engines are professional devices, so they are more often used in production. Gas engines are economical in terms of fuel consumption. Petrol and gas generators are perfect for household needs.
With power . The indicator starts at 1 kW. For domestic conditions, a model with a power of 1 to 10 kW would be a good option. If you need to connect more powerful equipment, then it is worth purchasing a generator with a power of 10 kW or more.
Pay attention to phasing . Devices are single-phase and three-phase. The first types are intended for connecting only single-phase users, the second - single-phase and three-phase. Models with a voltage of 380/220 V are in demand because they can be used to carry out complex construction work.

The Hyundai HHY 10000FE-3 ATS gasoline generator for domestic and professional use is capable of supplying country houses and construction sites with electricity. Consumers with high starting current (for example, concrete mixers) and a total power of up to 8.0 kW can be connected to it.

Switching from 380 volts to 220V and back is provided by the built-in power switching function. The automatic regulator successfully copes with voltage surges and protects against short circuits. The working tools of consumers will not be damaged in case of unstable power supply. The fuel reserve in the fuel tank is enough for 14 hours of operation at 50 percent load.

The self-resetting mechanism will close the cover to protect the socket from construction dust or dirt. A display and an hour meter are installed on the front side.

ATS or generator with additional function

Automation unit ATS 10-380
Automatic start of the generator during power outages is implemented in one of the following ways:

By purchasing a separate ATS unit and coordinating its operation with a generator already in the house that does not have this option.
Using a generator device model with the ATS function.

Each of these options has its own advantages and disadvantages. In the first case, you will have to put up with additional costs with minimal benefits. The second approach seems more preferable, since you can save significantly on it without losing the quality of the device.

If the purchased generator has an electric starter, you can do without the ATS. To transform it into a generator with an automatic transfer switch, the design will need to be modified.

Video description

Generator with autostart for home and garden. Autonomous and practical solution.

Types of ABP

All automatic reserve input blocks can be classified according to the following criteria:

voltage;
reserve input sections (quantity);
type of network (single- and two-phase);
power.

The connection diagram for automatic generator start can be configured so that not all wiring fed by the main source is started, but only those units where shutdown may be critical. For example, in a hospital this is how an intensive care unit and operating room are connected, and in the private sector a workshop and/or sawmill. This is not difficult to do: when installing the wiring, vital or technically critical blocks are output separately from all the others, so the ABP is inserted directly into this circuit.

ABP device

The simplest ATS circuit for a three-phase network Source piter220.ru
All automatic generator start systems consist of three main blocks.

Contactors or terminals for switching input and load circuits;
Logical and indicating devices.
Relay blocks responsible for controlling (start/stop) the generator.

ABP can become a lifesaver not only when the main power line is disconnected, but also during voltage dips, which can sometimes occur in suburban areas due to weak transformer substations. That is, the inclusion of a start function in the circuit when the voltage drops to 90% (instead of 220 V - 200 V) of demand. This will allow the electric motors to operate without interruptions and unnecessary load. With this option, generator autostart systems allow you to save on repairs and the purchase of new equipment. The contact group is responsible for starting the reserve circuit, and the input voltage is monitored by the RKF or phase control relay.

The simplest ATS circuit for a single-phase network Source asutpp.ru

Now, using the diagram above, let’s take a closer look at how a diesel or gas generator with automatic start allows you to eliminate dips (complete shutdown or drop) in the voltage from the main power source. Here, too, everything is very simple: when ≈220 V is supplied stably, the phase control relay keeps the terminals in the normal closed state. If there is any breakdown on the power line side, the saturation of the RKF solenoid becomes weak and cannot hold these terminals, hence they open. In those situations where an inverter is present, as indicated in the above diagram, it will begin to generate ≈220 V, which is necessary for the consumer. If the main power cannot be restored within the time set depending on the power of the batteries, then the controller sends an autostart command to the generator.

As soon as the contactor block receives voltage from the main transformer substation, the automatic generator start system operates in the reverse order - the terminals are switched and the entire circuit is powered according to the intended design. To put it simply, the signal when restoring the transformer from the power line gives a command to shut off the fuel hose, be it gasoline, diesel fuel or gas. The valve blocks the fuel supply and the engine stops.

How to start a gasoline generator?

Each generator starts differently. It depends on what type of launch it is equipped with. There are several ways to enable it:

Manual. The device must have a special handle that starts the work.
Electronic. More convenient and simpler activation is carried out by turning the key in the battery built into the housing.
Auto. Turns on automatically after a drop in mains voltage.
Remote. To turn it on, a remote control is included.

Before starting, you should study the instructions for use in detail for safety and more efficient operation of the device.

Generator autostart unit

As an automatic input of a reserve, we will consider in more detail the BAZG-1 device, which is a generator autostart unit. With its help, remote control is provided that does not require the presence of people. The main function of the unit is to start and stop the power plant engine. There are five attempts to start, including 5 seconds for the start itself, and 15 seconds for a break between starts with automatic control of the air damper.

The BAZG-1 unit is part of the automatic backup power supply system. An external source issues a command that starts and subsequently controls the operation of the engine. In order for the system to work fully, you will need a shield that switches to reserve.

The BAZG-1 device can work in conjunction with an inverter, which provides starting of the generator and further recharging of the battery. The generator starts and stops by closing and opening two contacts. If the startup attempt is unsuccessful, the unit goes into emergency mode. To exit it, you need to remove power from the unit or cancel the start command. The generator cools down for 30 seconds before shutting down the engine completely.
