Why is my OutBack Power FLEXmax 60 Controller FLEXmax not producing expected power?

If your OutBack Power Controller FLEXmax is not producing the expected power, several factors could be at play. Check PV conditions to ensure there are no clouds, partial shading, or dirty panels. Verify the current limit set point in the Charger menu is appropriately configured. If the batteries are fully charged, the FLEXmax will only produce enough power to maintain the voltage at the Absorption or Float stage. Problems with the array or wiring can also limit power output, so determine the specified short-circuit current of the PV array. Finally, high temperatures can affect performance, so check the PV array temperature.
