TROUBLESHOOTING GUIDE
MX60 does not boot/power-up (blank LCD)
• Check the battery connection and polarity.
• Check the battery breaker.
• A battery voltage below 10.5 VDC may not power up the MX60 (measure the battery-side of
Four- Position Terminal Block).
• If the MX60 still does not power up, call the factory for additional support.
MX60 is always SLEEPING
• If the battery voltage is at or above the ABSORB voltage set point (compensated ABSORB
voltage), the MX60 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).
• Confi rm 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?
MATE.
• Does the PV array voltage on the display rise with the PV breaker OFF, but reads 000 with the PV
breaker on?
be shorted.
• Does the PV voltage still read 000 with the PV breaker off after a minute?
• Have you checked the short circuit current of the PV array?
test will not harm the array.

Reverse polarity or an improper connection will cause power-up issues.
Ensure that the battery breaker is sized appropriately.
GT mode is only applicable with a HUB 4 or HUB 10 installations with a grid-tie compatible
If so, the PV array polarity connection on the MX60 maybe reversed or the PV lines could
Call the factory for support.
Use a multi-meter to determine if a short circuit current is detected. The short circuit current
