VertiGo SRG Wind Generator

Vertical axes slow rotation generator

Thanks to the consistent and hard work of its Hungarian designers, the VertiGO SRG wind power utilisation equipment was created in 2014. As a result of the development, this extremely low-noise (silent), environmentally friendly, cost-effective, high-capacity, long-life wind generator requiring no maintenance cycles and capable of generating electric power starting from a wind speed of 0.5 m/s but also working safely in a wind storm has become a marketable product thanks to its unique installation and setting parameters adjusted to the environmental conditions.

Technical specification

  • Off-grid, i.e. designed to recharge a set of batteries: 12-24-48 V
  • Regenerative type with 1 or 3 phases. Takeover of generated power is required by law, using two-directional electricity meter, with annual reading and settlement.
  • Combined version: for the purposes of the highest safety and independence, the feed-back unit can be extended with battery charger and battery pack to overcome power outages and shorter periods of calm weather
  • Capacity levels: 1.5 kW-50 kW (net, 230V or 110 V alternating current based on capacity depending on inverter, as required)
  • Starting wind speed: 0.5 m/s (thanks to the special design of the coils, it starts with a “breeze” as well and, for the same reason, there is no resonance)
  • Rated capacity wind speed: 8.3-10 m/s
  • Survival speed: virtually unlimited (as due to its physical structure, it cannot accelerate above a certain rpm, it does not need to be slowed down, rotating and generating power in storms as well)
  • Revolutions per minute: 6-50 rpm, work phase 25-40 rpm (revolutions per minute)
  • Wind direction: the equipment can receive wind from any direction, both fast-changing continental winds and gusts and the turbulent wind generated by terrain objects
  • Can be installed in groups of 3 to reinforce each other
  • Number of blades: 5-8
  • Width/Height: widely customisable, e.g.: 2.40 x 3.60 m
  • Drive: direct drive without engine
  • Coils: coils with unique technical solutions
  • Magnets: permanent (super) magnets
  • Brakes: in working condition, electronic work load, during assembly, manual or electronically operated drum/disc brakes
  • Regulation: inverter-dependent charging control electronics supplied with the system
  • For the event of a power outage, a galvanic isolator will be built in to avoid electric shock
  • Noise: 40 dB (lower than the surrounding environmental noises e.g. the sound of the wind - virtually inaudible)
  • In modular system, located side by side or above each other to multiply performance
  • Mounting height: accident zone, i.e. above 3 m, but it does not require a great height, or a costly pole, requires no building permit, can be easily mounted on the roof as well
  • Weight: between 180-240 kg (5-18 kW), made of fully recyclable materials
  • Maintenance: low requirement with only an annual inspection
  • Service life: over 30 years (no wear parts apart from the bearings) blades with sea-proof fibreglass cloth and epoxy, magnets with nickel-copper-nickel coating, metal parts are galvanised, flexible, treated with impact-resistant and UV resistant coating, stainless steel fasteners, coils cast in resin, electronics in standard shock-proofed outdoor box.
  • Pole module: arbitrary, according to structural engineering regulations, recommended dimension: 6-18 m, steel, reinforced concrete or metal posts
  • The wind generator is made in the manufacturer's plant in Hungary.
Electrical system


The electrical system of
Vertigo SRG wind generator

1.  Off-grid equipment
2. On-grid equipment


Off-grid equipment

In this case, the equipment is in “off grid” mode. In this mode, the system
charges batteries. It produces alternating current from the batteries with the help
of an inverter. With the “excess current” produced with this application and stored,
the equipment can supply power consumers even in the case of calm weather or a power failure.

It is especially recommended

  • in places where the electricity supply is not installed,
    unstable, or difficult to install
  • for environmentally conscious consumers who wish to be self-sufficient
  • for boats and as power generation equipment for water facilities
  • in the event of off-grid equipment, the customer’s electric network
    can be connected to the operator’s grid after disconnecting the
    off-grid equipment

Regenerative equipment

The regenerative equipment is directly connected to the electricity supplier’s grid.
The unit feeds back the electric current produced at the site of consumption into the grid
and the required quantity can be used from the grid as usual. In such cases, the regenerated
energy and the energy used is recorded by a meter that can measure in both directions and
invoices the total annually. The supplier will then pay for any extra energy generated
(only the price of electricity but not the system usage fee). In this mode of application,
the objective is not to sell electricity, but to bring the annual electricity bill
to “HUF 0.-” with the help of a well optimised equipment.

Technical information

Coming soon



  • The wind generator does not require significant maintenance.
  • The structural engineering control of the structure must be carried out annually.
  • Checks and maintenance of electrical devices and equipment in
    accordance with electric shock protection regulations
    must be performed annually.
  • Wear and tear of rotating parts must be considered in the long run.
    In practice, this means the replacement of the bearings (usually after 10 years
    of continuous operation). Over 30 years of intended service life!
  • In the case of off-grid equipment, account must also be taken of the usual wear
    cycle of batteries (modern batteries have a service life of
    3,000-5,000 discharge-recharge cycles and a lifecycle of 8-10 years)
  • Based on a flat-fee contract, the manufacturer-distributor provides
    the necessary maintenance and checks.


The manufacturer or distributor offers 2 + 2 years’ extra warranty
in addition to the operative safety and operating conditions of the equipment
as offered by the manufacturer. The warranty is valid in case the principles
and practical rules set out in the contract handed over to the
operator or the owner after commissioning are complied with, the
terms and conditions of proper operation are observed and
extended with custom conditions (e.g. a natural disaster,
operational disaster, acts of God, etc.).
We possess the “CE” certifications for commercial
distribution, the related permits, technical
documents and the manufacturer’s ISO 9001
quality system certification.
