Generators

VARI offers four models of quiet single-phase inverter generators equipped with reliable Zongshen engines, which have been used in other machines for many years. Power outputs ranging from 2000 W to 5500 W cover most common requirements for backup use. The top model, the ECV 5500 W, also includes an electric start.

Comparison of the basic parameters of VARI generators

ECV 2000 W - easily portable, 1x 230 V / 16 A socket, 2x USB port, runtime approx. 5.5 hours, possibility of parallel connection of two generators

ECV 3500 W - pull-out handle, wheels, 2x 230 V / 16 A socket, 2x USB port, 1x DC 12 V / 8.3 A socket, runtime approx. 7.5 hours

ECV 4600 W - frame design, 2x 230 V / 16 A socket, 1x DC 12 V / 8.3 A charging socket, runtime approx. 6.5 hours

ECV 5500 W - pull-out handle and wheels, 1x 230 V / 16 A socket, 1x 230 V / 32 A socket (3 poles), 2x USB ports, runtime approx. 5.5 hours, electric start button with automatic choke

 Single-phase generators can power single-phase electrical appliances (230 V), such as small power tools, lighting, inverter welders, chargers, home electronics, TVs, computers and monitors, various players, heaters, cooling equipment, fans, refrigerators, or measuring equipment, etc.

 Inverter generators use computers to modulate both the voltage waveform and magnitude as well as frequency stability regardless of engine speed, providing exceptionally high-quality electrical current. Inverter technology enables to construct an exceptionally compact generator with an alternator that is almost half the size and weight of conventional generators with other output voltage controls of the same power. Inverter generators are the ideal power supply for highly sensitive electronic devices such as computers, providing optimized electrical energy for both reactive appliances and electronic devices. This also ensures maximum performance and long service life of the powered appliances. Inverter generators are mainly manufactured in fully soundproofed, bonneted, or suitcase designs with minimal noise, very low weight and fuel consumption.

Noise is one of the most important parameters directly affecting the possibility of using a generator. The lower the operating noise, the wider the possibilities for using the generator. The highest level of noise reduction is provided by fully enclosed suitcase-type inverter generators, which are additionally equipped with a special integrated exhaust silencer and engine silent blocks, namely the VARI ECV 2000 W, ECV 3500 W and ECV 5500 generators.

The ECV 4600 W generator uses a larger exhaust silencer and a multiple silent block system to reduce vibrations, ensuring that even this partially covered frame design stands out for its extremely quiet operation.

Another advantage of inverter technology is the possibility of parallel operation, or ‘phasing’ of two identical generators. Using special connecting cables for parallel operation, two identical generators can be connected to double the electrical output. Depending on current needs, this ensures the possibility of powering larger appliances without having to replace the generator with a larger and heavier one. Conversely, both generators can also be disconnected from each other and used separately. The VARI range offers this possibility of pairing ECV 2000 W models.

Information display

All models are equipped with an information display and basic control diagnostic LEDs. Other practical features include a display showing the current power usage of the generator in %, the output frequency in Hz, and the total and operating hours since the generator was started. Another practical feature is oil level monitoring, which protects the generator engine from seizure.

Easy handling and transport

The low weight of the ECV 2000 W model and its comfortable handle allow the generator to be carried like a small suitcase. The larger ECV 3500 W and ECV 5500 W models also have a pull-out handle and large transport wheels. The ECV 4600 W frame generator can be carried and fixed using its robust frame.

Sockets

VARI generators are equipped with a SCHUKO socket system, which is used in Germany and many other European countries. These are standard European sockets, which use flat connectors on the top and bottom of the socket for grounding. UNISCHUKO plugs can be used in these sockets, which are now fitted to the vast majority of appliances.

If you happen to still have an old appliance with for example a classic Czech plug, a new extension cord with a universal UNISCHUKO plug on one side and one or more classic Czech sockets with a grounding pin on the other side will serve you very well (as an adapter for use in a SCHUKO socket).

IP protection rating

All VARI generators have IP 23 M protection (protection level), which means they are sufficiently protected against electric shock in the event of dangerous finger contact, are resistant to the ingress of small foreign objects and are also protected against sprays of water up to 60 degrees from the vertical onto the device, at a flow of 10 liters per minute and a pressure of 80-100 kN/m² for at least 5 minutes, i.e. against rain or water sprinkling. This protection has been tested with moving parts in motion. IP 23 protection is standard for generators also from other manufacturers.

What are the various VARI generators suitable for?

Quiet, powerful and affordable VARI generators have a wide range of applications as mobile and backup power sources for regular use in cottages and cabins, for camping and caravans, outdoor events, or as a backup source in case of bad weather, power outages, or as a certain guarantee of user independence in emergency events. They are suitable wherever a stable and reliable source of electrical energy is needed. The choice of generator depends on the users and their requirements, i.e. what appliances they will be using. It is always a good idea to consult it with a specialist in the VARI dealer network to make the right choice, as well as for any servicing or spare parts orders.
