Re-Cal
There are certain abnormal conditions that can confuse the current
measuring method in the MPPT. When and if this happens, the MPPT will
temporarily stop and re-calibrate. This may sometimes happen because
of negative current, i.e., current coming out of the input terminals instead
of into the input terminals turbine breaker. A new voc is also acquired
during a Re-Cal.
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 6V. A battery voltage
less than 14V 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 Turbine's 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 turbine's breaker (or fuse) to 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 the
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 below15mph than one at a site with speeds in the low 20mph
range.
