55 TriStar MPPT Operator’s Manual
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 TriStar MPPT. Battery volt-
age must be 8 Vdc or greater. If the voltage on the battery terminals of the controller is between
8 and 72 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 TriStar MPPT is not charging the battery.
Solution:
Check the three (3) battery SOC LEDs. If they are fl ashing a sequence, see
Section 4.4 Faults &
Alarms
of this manual to determine the issue. If a TriStar Meter 2 is connected, the diagnostics
menu will display reported faults and alarms.
If the LED indications are normal, check the fuses, breakers, and wiring connections in the solar
array wiring. With a multi-meter, check the array voltage directly at the TriStar MPPT solar input
terminals. Input voltage must be greater than battery voltage before charging will begin.
NOTE:
For more in-depth testing and diagnosis, download the TriStar MPPT Testing Document from the
Support section on our website: www.morningstarcorp.com/
Network and Communication Issues
Problem:
Cannot connect to the controller via RS-232
Solution:
Check the following:
• The RS-232 cable is straight-through, not a Null Modem (cross-over)
• If using a serial-USB adapter, verify that the adapter software is installed and a serial COM
port has been mapped. Check the activity light on the USB adapter if it has one. If there is
no activity, the wrong COM port has been chosen or there is a con
fi guration issue with the
adapter.
• The default MODBUS ID of the TriStar MPPT is 1. Verify that the PC software is con fi g-
ured to communicate using the correct ID.
