Why is my OutBack Power FLEXmax 100 Controller unit not producing expected power?
There might be several reasons why your OutBack Power Controller isn't producing the expected power. Check the PV and battery voltages, PV conditions, battery conditions, and charging stage. Also, determine the specified short-circuit current of the PV array, and check both the PV array and the FLEXmax 100 external temperatures.
What to do if my OutBack Power Controller displays 'Fault Input Active'?
A 'Fault Input Active' message indicates a deliberate action due to a rapid shutdown condition, which is not a controller error. Resetting this condition requires resetting the external rapid shutdown device.
Why is charging not temperature-compensated on my OutBack Power FLEXmax 100?
Charging may not be temperature-compensated because the FLEXmax 100 is performing equalization, which is a function that is not temperature-compensated. It could also be caused by a damaged Remote Temperature Sensor (RTS). To test, remove or replace the RTS.
What does it mean when the red FAULT indicator is lit on my OutBack Power Controller?
A lit red FAULT indicator suggests a ground fault. The detection circuit has sensed an open connection on the GFDI fuse. Check the fuse and ensure it is installed according to the instructions.
What to do if my OutBack Power FLEXmax 100 unit powers up but does not operate?
If your OutBack Power Controller powers up but doesn't operate, and the PV voltage drops when connected, the PV array wiring polarity may be reversed. Check the PV wiring.
Why is my OutBack Power FLEXmax 100 not operating, but had worked normally before?
This behavior can be normal in cases of low light. Confirm conditions and behavior using Table 4 on page 34. It could also be due to a battery temperature fault, so check the temperature. Also, a rapid shutdown condition may cause this, so try resetting the external rapid shutdown device.
What to do if my OutBack Power Controller shows a GFDI Fault?
A GFDI Fault indicates a ground fault where the detection circuit has sensed an open connection on the GFDI fuse. Check the fuse and make certain it is installed according to the instructions.
What to do if my OutBack Power FLEXmax 100 is in over current fault?
An over current fault occurs if more than 80 amps flow from the battery to the FLEXmax 100, or if more than 120 amps flow from the controller to the battery. To restart the FLEXmax 100, remove all power from the controller and then reconnect the batteries.
What does it mean when my OutBack Power Controller displays 'VOC Too High'?
If the open-circuit voltage (Voc) is too high, the FLEXmax 100 cannot safely operate. The controller will automatically restart operation once the Voc decreases to a safe level. You should also check the controller temperature.
What to do if OutBack Power Controller unit does not power up upon initial connection?
If your OutBack Power Controller unit doesn't power up, check the battery connection and polarity, ensuring it's properly connected. Also, inspect the battery circuit breaker or device to ensure it's appropriately sized. Confirm the battery voltage at the FLEXmax 100 terminals, as a voltage below 15 Vdc may prevent power-up. If a rapid shutdown device caused this, reset the external rapid shutdown device.
