TROUBLE-SHOOTING AND/OR SERVICING AN ARK BATTERY SHOULD ONLY BE PERFORMED BY A
QUALIFIED INDIVIDUAL.
WHEN CALLING FOR TECHNICAL ASSISTANCE, PLEASE HAVE A DC VOLTMETER WITH A VOLTAGE RANGE
OF 0-60VDC ON HAND.
FAULTS:
DISPLAY SCREEN IS BLANK:
TEST FOR VOLTAGE ON BATTERY TERMINALS WITH BREAKER IN ‘ON’ POSITION. IF NO VOLTAGE IS
PRESENT, PROCEED TO STEPS OUTLINED IN ‘LOW-BMS CUTOUT’ BELOW. IF VOLTAGE IS PRESENT, CALL
FOR FURTHER ASSISTANCE.
BMS LOW CUTOUT:
APPPLY VOLTAGE TO TERMINALS TO ‘WAKE UP’ THE BATTERY.
CAUTION:
NEVER ‘JUMP’ WITH ANOTHER BATTERY. USE A BATTERY CHARGER THAT PERFORMS WITHIN

24V: MEANWELL GC120A24-AD1
48V: MEANWELL GC120A48-AD1
DISCONNECT ALL CHARGING/DISCHARGING SOURCES UNTIL BMS HAS TURNED BACK ON.
BMS HIGH VOLT CUTOUT:
DISCHARGE BATTERY UNTIL THE CHARGING PORTION OF THE BMS TURNS BACK ON.
PREMATURE BMS HIGH/LOW CUTOUT:
IF THE BMS SHUTS OFF DURING A CHARGE CYCLE BEFORE REACHING ABSORB VOLTAGE OR SHUTS OFF
DURING DISCHARGE BEFORE REACHING ‘RECOMMENDED INVERTER LOW VOLT CUTOUT’ (PAGE 6), CALL
FOR FURTHER ASSISTANCE.
