MPPT is inactive
1. Is battery voltage greater than the absorb voltage set point (compensated absorb voltage)? If
yes, the MPPT will not wake up since the battery voltage is at/above the absorb target voltage set
point.
2. Is the Turbines voltage greater than the battery voltage by at least 2 volts?
The output voltage has to be at least 2 volts greater than the battery voltage for the initial
wakeup.
3. Check the turbines breaker (or fuse) ensure that the turbines breaker (or fuse) is sized
appropriately.
MPPT not producing expected power
1. Are wind conditions optimal?
Wind turbines in locations with constantly high wind speeds bring best return on investment.
The primary consideration in a wind generator is the average wind speed at the installation site. A
different turbine will give optimum performance at a site with average wind speeds below 15mph
than one at a site with speeds in the low 20mph range.
2. Are the batteries charged? Is the MPPT in the absorbing or float stage?
If so, the MPPT will produce enough power to regulate the voltage at the absorption or float set
point voltage, therefore, requiring less power in these
modes.
3. What is the short circuit current of the wind turbine? Use a multimeter to determine if a short
circuit current is as expected. There might be a loose/faulty wire connection.
4. Is the turbine’s voltage close to the battery voltage?
If so, the panels could be warm/hot causing the Maximum Power Point of the array to be at or
lower than the battery voltage.
MPPT sweeping frequently
1. What is the current limit set point?
When the current limit set point is achieved the MPPT will continue sweeping to maintain the
targeted current limit.
2. What is the sweep interval set point?
A short sweep interval time will cause the MPPT to sweep frequently. A sweep interval of 7 to10
minutes is recommended.
MPPT Internal Fan
1. Should the internal fan be running when the MPPT is producing power?
•
The internal fan will only run when the internal temperature has reached ~ 65 degrees
Celsius or 149 degrees Fahrenheit.
