We have two D400
wind turbines and one of them has a vibration or resonance that goes through the
boat once the
batteries exceed 14.2 volts. There are also two
Victron MPPT solar chargers for the 1000 watts of
solar so these controllers bring the voltage up beyond the 14.2 volts to reach the proper absorption voltage.
The dump resistors are seeing
current during this time so the
regulator appears to be doing what it’s supposed to do.
It sounds almost like the load is going on and off the turbine rapidly above 14.2v.
Has anyone experienced this type of issue before?
