5.3 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. 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 is not charging the battery.
Solution:
Check the three (3) battery SOC LEDs. If they are
flashing in a sequence, see Section 5.2 - LED Fault
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
wiring. With a multi-meter, check the array voltage
directly at the ProStar solar input terminals. Input
voltage must be greater than battery voltage before
charging will begin.
