Most wind turbines are three-phase PM type. Therefore, either a wind turbine controller or a direct
connection to the MPPT via a simple protection circuit will be required.
Dump Load:
When the battery (battery bank) is fully charged and the water turbine/wind turbine/solar
module is still generating power, a dump load will provide the electricity a path to flow. This can be done
using a switch on by the smart load option or utilizing a wind turbine controller with a built-in dump load.
Also, the hot water tank controlled via smart load can act as a good dump load, but in very windy
conditions it may be necessary to shunt the output.
IMPORTANT
DO NOT use a wind turbine that exceeds 400V.
Use a self breaking wind turbine
. Once the batteries are fully charged and the inverter is not
exporting any power the load can drop. This can cause the turbine to speed up dramatically, which
can be very dangerous and usually happens suddenly. Thus, it is essential to use a self breaking
turbine.
