Energy Ball V200® (grid)

Energy Ball V200® (off grid)





Energy Ball V200® (Grid connected)

The Energy Ball® V200 is an artistic spherical wind turbine with 5 rotor blades and a diameter of 1.98 m which you can use to produce some of your own electricity supply soundlessly. We deliver the complete Energy Ball® package and then install it for you on a mast reaching 12 or 15m in height.

The Energy Ball® V200 also comes with a WindPower Inverter. This converts the electrical energy generated by the Energy Ball® V200 into electricity with a suitable specification for supplying to the mains. (230 Vac, 50 HZ). The WindPower Inverter is connected to a distribution circuit in your electric installation. You can start to use the electricity which has been generated immediately. If you use less energy then the Energy Ball® will deliver to the grid, which immediately results in negative measurement of your grid electricity meter.

The Energy Ball® V200 supplies the maximum amount of power at wind speeds of 19 m/s (wind-force 8 to 9 on Beaufort scale). The Energy Ball® V200 can produce a maximum of 2500 W (see specifications). This maximum power is not supplied to the mains, but rather the power supplied by the generator. If the generator supplies maximum power, this is supplied directly to the mains by the WindPower Inverter 2250 W at 230 Vac and 50 Hz (see Power Curve Energy Ball® V200).

The Energy Ball® V200 can produce an output at the mains of between 240 kWh and more than 2000 kWh each year, with a respective wind regime in the installation location of between 4.0 and 7.5 m/s. This will occur as long as the Energy Ball® V200 has been installed free of surrounding obstacles and attached to a mast which is 15 m high.

Average wind speed Output / year
m/s [Beaufort] [kWh]
7,5 4 - 5 2200
7 4 - 5 1750
6 4 1000
5 3 - 4 500
4,5 3 340
4 3 240

Please note that the mentioned annual output is based on an optimal installation, a laminar air flow over the Earth’s surface and low surface roughness. Please note that due to variability in the wind the annual output may actually be much less or much more; annual variability of 15% or more is normal.

We recommend that, prior to ordering, you look into which wind regime applies to your region. The Energy Ball® V200’s total annual output will also be determined by the conditions in your area. Large buildings, turbulence and trees or other vegetation can have a negative effect on the Energy Ball®’s output. The wind in the Netherlands, for example, is often south-westerly. Positioning the Energy Ball® V200 so that the wind from that direction has clear access to it, will therefore have a positive effect on output. Positioning the Energy Ball® as high as possible also produces a better output.
