Mastervolt Windmaster 500 Grid-Tie Inverter

The Windmaster 500 is a grid connected inverter for connecting small wind turbines. Its design is based on the successful Soladin 600 Solar inverter, some 6000 of which have already been sold by Mastervolt for small 4-6 module based grid connected solar systems. The Windmaster 500 offers a simple solution when connecting a 500 watt turbine to your household mains supply. With it's light weight and compact size, the Windmaster 500 can be installed inside existing meter cupboards or in outbuildings (but it is not suitable for outdoors). Connection to the input of the inverter is provided by 2 dedicated DC power plugs. The output should be connected in accordance with the electrical requirements for the country of installation.

In low wind sites it is advisable to use only one inverter with a 500 watt turbine, since over 90% of the power produced by the turbine will lie under the 500W export power limit of the inverter. For higher wind speed sites we suggest 2 inverters, connected in parallel to handle the full power of the turbine. No charge controller is required when using these inverters since they can handle a much higher input voltage than the turbine can produce, even in power-cut situations. In "Hybrid" systems (those involving both wind turbines and solar PV), use the standard Soladin 600 inverter, keeping the installation simple and very neat.

The Mastervolt Windmaster inverter has a power rating of 500 Watt continuous with an input voltage window between 40-125V  DC
