TROUBLESHOOTING
MPPT does not boot / power-up
1. Check battery connection and polarity. Reverse polarity or improper
connection will cause power-up issues.
2. Check if the battery voltage is greater than 10.5v. A battery voltage
less than 10.5v may not power up the MPPT.
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.
