5.2 Battery Charging and Performance Issues
Problem:
No LED indications, controller does not appear to be
powered
Solution:
With a multi-meter, check the voltage at the battery
terminals on the ProStar MPPT. Battery voltage must be 10
vdc or greater. If the voltage on the battery terminals of the
controller is between 10 and 35 vdc, and no LEDs are lit,
contact your authorized Morningstar dealer for service.
If no voltage is measured, check wiring connections, fuses,
and breakers.
Problem:
The ProStar MPPT is not charging the battery.
Solution:
Check the three (3) battery SOC LEDs. If they are flashing in
a sequence, see Section 4.5 LED indications of this manual
to determine the cause. A metered model, an RM-1 meter,
or MSView PC software will display active faults and alarms.
If the LED indications are normal, check the fuses,
breakers, and wiring connections in the power source wir-
ing. With a multi-meter, check the array voltage directly at
the ProStar MPPT solar input terminals. Input voltage must
be greater than battery voltage before charging will begin.
Problem:
Controller makes buzzing and humming noises.
Solution:
No action is required. This is expected due to magnetic
resonance and circuit switching.
If troubleshooting does not correct the problem, please
refer to Morningstar's Warranty Claim Procedure in
Section 6.
