. Troubleshooting Guide
FLEXmax 80 does not boot/power-up (blank LCD)
• Check the battery connection and polarity.
• Reverse polarity or an improper connection will cause power-up issues.
• Check the battery breaker.
• Ensure that the battery breaker is sized appropriately.
• A battery voltage below 10.5VDC may not power up the FLEXmax 80 (measure the battery-side
of wire lugs).
• If the FLEXmax 80 still does not power up, call the factory for additional support.
FLEXmax 80 is always SLEEPING
• If the battery voltage is at or above the ABSORB voltage set point (compensated ABSORB
voltage), the FLEXmax 80 will not wake up.
• The PV voltage has to be at least two volts greater than the battery voltage for the initial wakeup.
• Check the PV array breaker (or fuse).
• Confirm the PV array breaker (or fuse) is sized appropriately.
• Which State (in
MISC Menu) is it at? Is it transitioning between 00 and 01? Is it in GT mode and
connected to a MATE?
• GT mode is only applicable with a HUB 4 or HUB 10 installations with a grid-tie compatible
MATE.
• Does the PV array voltage on the display rise with the PV breaker OFF, but reads 000 with the PV
breaker on?
• If so, the PV array polarity connection on the FLEXmax 80 maybe reversed or the PV lines
could be shorted.
• Does the PV voltage still read 000 with the PV breaker off after a minute?
• Call the factory for support.
• Have you checked the short circuit current of the PV array?
• Use a multi-meter to determine if a short circuit current is detected. The short circuit
current test will not harm the array.
FLEXmax 80 not producing expected power
• Clouds, partial shading, or dirty panels can cause poor performance.
The lower current limit set point in the Charger menu will yield a loss of power or poor
performance symptoms.
