In many places our small wind turbine produces energy for personal use and the surplus is sold to the network. In other cases, all the electricity flows into the network and nothing is accumulated. In these cases it is not necessary to use batteries.

WINDSPOT small wind turbines generate alternating electricity, at a voltage and frequency that varies depending on the wind. Later, a controller converts this energy to direct current, at a voltage acceptable to the inverter.

If there is an excess of power, the controller diverts the surplus energy to discharge resistors that act as a brake and dissipate the surplus energy as heat.

The direct current that leaves the controller is already ready for the inverter to convert it again to alternating current at the voltage and frequency required by the distribution network.
