6 TROUBLESHOOTING AND SUPPORT
The TrakMax is ruggedly constructed and requires minimal care. It is recommended to inspect all the controller
connections two times per year for insulation damage or corrosion and to ensure all connections are tight and
secure.
CAUTION: Shock Hazard
Disconnect all power sources to the controller before removing the wiring box cover. Never remove the cover
when voltage exists on the power connections.
6.1 C
ARE
•
Clean the heat sink and area around the controller of any dirt or debris with a moistened cloth.
•
Ensure controller air vents are clear of obstructions.
•
Tighten the screws on the terminals. Inspect for loose, broken, or burnt wire connections.
•
Inspect the battery bank for cracked or bulging cases and corroded terminals.
•
For wet cell flooded batteries, make sure the water level is maintained according to the manufacturer's
recommendations.

does not appear to be powered
Charge LED on, but no
output charge current
Unit is on, but charge status
LED is off
Charge current or PV current is
lower than expected

• Check the battery voltage
• Check internal fuse for damage.
• Restart the solar charge controller.
• Adjust charging current
• Check the DC load.
• Reduce Load
• Check the temperature sensor.
• Check ambient temperature surrounding batteries
• Increase ventilation around batteries
• Check ambient temperature surrounding controller
• Increase ventilation around controller
• Check air vents on controller for blockage
Possible Remedies
• Check the voltage at the battery terminals on the TrakMax. Battery voltage
must be a constant 12 VDC or greater. If no voltage is measured, check
wiring connections, fuses, and breakers.
• If the voltage on the battery terminals of the controller is between 12 and 36
VDC and no LEDs are lit, contact your dealer for service.
• Is the battery voltage greater than the charge voltage set point? This is
normal operation. Output is off due to high battery voltage which may be
caused by other charging systems.
• Battery voltage must be at least 9VDC for the unit to operate.
• Check PV connections for reverse polarity.
• PV must supply at least 0.25Amp at 3V more than battery voltage to begin
charge.
• Check ground (-) connections. PV- & BAT- must be separate for operation.
• Check battery voltage, current is reduced if battery voltage is at set points.
• Check atmospheric haze, dirty PV's, or sun low on horizon, etc.
• Check PV voltage; if system has been changed from 24VDC to 12VDC (or
vice versa), battery and PV power must be momentarily disconnected from
the TrakMax to reboot the unit and load initial 12 or 24VDC control values.
• Check ground (-) connections. PV- & BAT- must be separate for operation.
