Fault Message
Symptoms and Troubleshooting
Battery low voltage!
PRO-Verter is in Fault mode because the battery voltage has dropped to the set lower
threshold of Batt Low Voltage.
• When the battery voltage drops to the set lower threshold of Batt Low Voltage,
activation of this fault protection is initiated. The red Fault LED will flash once per
second and the alarm in PRO-Verter will beep once per second. The inverter will
continue to operate normally and the blue Status LED will continue to be on steady.
(
Note:
Fault message “Battery low voltage!” will not be displayed during this time.)
• If the battery voltage stays at or below the threshold setting for a duration equal to the
set LV Detect Time, only the inverter will be switched off and fault message “Battery
low voltage!” will be displayed. The red Fault LED will now change to steady on, the
blue Status LED will switch off and the alarm in PRO-Verter will now beep steady. If the
“Battery low voltage!” fault condition is not reset within the LV Cut Off Time, the PRO-
Verter will shut down completely after the LV Cut Off Time (LCD screen/LED/Alarm will
be off) has expired.
• If the batteries are being charged by the PV array and the battery voltage recovers to
the set Reset Voltage before LV Cut Off Time time expires while in “Battery low voltage!”
fault condition, the inverter will restart and “Battery low voltage!” fault condition will be
cleared.
• While in “Battery low voltage!” fault condition, if AC input is made available before the
expiration of LV Cut Off Time, the “Battery low voltage!” fault condition will be cleared.
The PRO-Verter will restart in Inverting mode, synchronize with the AC input, and then
transfer to the AC input at zero crossing. It will now operate in Charging mode.
Battery ultra
low voltage!
The PRO-Verter is in Fault mode because the battery voltage has dropped to 18 V or
lower.
(
Note:
A voltage this low will not be encountered when using LiFePO
4
batteries
because the battery’s own BMS will disconnect the output terminals before the voltage
drops that low )
