fan will continue running until the internal temperature is less than 104°F.
FLEXmax 80 is beeping
• When the FLEXmax 80 is in Extended Play mode, the array is very hot, and the MPP is close to the
battery voltage, or the nominal PV voltage is higher than the nominal battery voltage, beeping can
occur. To disable the Extended Play feature, go to the MAIN Menu and press and hold the #1 soft key
until the FLEXmax 80’s software version appears on the screen. Continue pressing the #1 soft key and
press the #3 soft key at the same time until X O displays on the screen. To reactivate Extended Play,
repeat these steps and hold the #3 soft key until X On displays. Extended Play is meant to optimize
the performance of a hot array, but isn’t critical to ecient FLEXmax 80 operations.
To enable/open the FLEXmax SELECT VERSION screens:
• Turn o the DC and array breakers
• Press and hold the rst and third soft keys
• Turn on the battery breaker
• Follow the SELECT VERSION screen instructions from the beginning of the manual
• Rebooting the FLEXmax 80 like this will return all the values and set points to the factory defaults.
