BATTERY CHARGER - If ERROR LED comes on, see ERROR CAUSES section.

PROBLEM

INDICATION SOLUTION

AC IN GOOD LED is flashing, but will not start charging

(allow 40 seconds to synchronize)

Check for the correct AC voltage or frequency at the AC input terminal.

Charger drops off before full charging has finished. (No ERROR comes on)

Check for the correct AC voltage or frequency using the Control Panel.

Charger drops off before full charging (or equalization) has finished

ERROR LED flashes and AC output drops momentarily.

AC frequency at the AC input terminal is out-of- tolerance (too high or low) or AC voltage outside ‘Upper/Lower VAC limit’ settings

AC frequency at the AC input terminal drops out-of- tolerance (too high or low) or AC voltage falls outside ‘Upper/Lower VAC limit’ settings.

Circuit breaker on inverter is open

Ambient temperature may be high causing unit to overheat and ramp down the charging.

Cold temperature around batteries with BTS (Battery Temperature Sensor) installed may be causing unit to reach HIGH BATTERY CUTOUT setting

If AC source is a generator, adjust AC voltage or frequency accordingly.

If AC source is generator, adjust AC voltage/frequency accordingly.

Reduce your ‘Set AC Amps’ setting to limit the pull on the AC source.

Open the ‘Upper/Lower VAC limit’ settings “window” to allow synchronization.

Engage circuit breaker on side of unit (press hard on breaker button to ensure it is engaged)

Cool the unit down or check the inverter cooling fan, or check for anything preventing air flow

Disconnect BTS during charging or increase HIGH BATTERY CUTOUT setting.

Charger drops off before full charging has finished.

(ERROR comes on)

Charger output is low

Batteries being charged above the Bulk/Float setting

See ERROR CAUSES section
Loose or corroded battery connections	Check and clean all connections
Loose AC input connections	Check all AC wiring connections
Weak/soft batteries	Replace batteries
Battery cables too small or too long	Refer to cable and battery
	recommendations in owner’s manual

NOTE: To bring batteries that are cold to the correct state of charge may require charging at a higher voltage. Remove the BTS and determine if your voltage returns to the bulk/float voltage

Temperature probe is installed

Temperature probe is not installed

LBX mode is enabled, but you do not want the unit to go into Float mode

(Float LED is ON)

Refer to the 'Battery TempComp volts DC' reading while charging.

Refer to the ''Battery actual volts DC' reading while charging.

Ensure your 'Set Low Battery Cut In VDC' setting is lower than the 'Set Bulk volts DC'' setting

(a)Ensure that the temperature probe is not in a cold area or has not fallen off the batteries.

(b)Ensure that there is no other DC charging source on the batteries

Ensure that there is no other DC charging source on the batteries

Low Battery Cut In voltage is set to high to prevent the charger from going into the float charge
