FLEXmax 80 is beeping
• When the FLEXmax 80 is in

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

displays on the screen. To reactivate
Extended Play
,
repeat these steps and hold the #3 soft key until
X On
displays.
Extended Play
