Inverter Standby: The inverter is in standby when the inverter is active (green INV
LED is on) and an external AC power (utility/shore or generator) is
passing through the inverter to power the AC loads. During
normal operation, the AC loads will be powered by the external
AC power. However, if a blackout or brownout condition occurs,
the inverter senses these conditions, transfers to Inverter mode
and powers the AC loads connected to the inverter.
Operation - Charger
Mode
Turning the charger on: The charger will automatically be activated and begin
to charge your batteries when acceptable AC power, utility/
shore or generator, is connected to the input (HOT IN
1) of the inverter. When the charger is ON, it produces
DC voltage and current to charge your batteries. The CHG
LED will be on when the charger is ON and actively
charging. While charging, the display will show Bulk,
Absorption, Float, or Full Charge.
Charger Standby: While the charger is actively charging, the ON/OFF CHARGER
pushbutton can be pressed to switch the charger to Charger
Standby. While the charger is in Charger Standby, the incoming
AC is still available on the inverter’s output, but the charger is not
allowed to charge. The display will show Charger Standby and
the CHG LED will flash when the charger is in Standby mode.
Note: To resume charging, momentarily press the ON/OFF CHARGER
button, or disconnect/reconnect AC power to the inverter’s input.
Equalize charging: Equalizing is a controlled overcharge performed after the
batteries have been fully charged. It helps to mix the battery
electrolyte to reverse the buildup of stratification and to remove
sulfates that may have built up on the plates. These conditions if
left unchecked, will reduce the overall capacity of the battery.
Do not perform an Equalization charge without reading
and following all safety precautions pertaining to
charging/equalization as noted in this manual and any
equalization information in your inverter’s owner’s
manual.
Troubleshooting Tips
- Inverter
Inverter turned on, green INV LED on inverter blinking, no output:
Inverter is in Search mode. Either turn off Search mode if not needed or turn on loads
greater than the Search Watts setting.
Troubleshooting Tips
- Charger
Unit won’t transfer to Charge mode with AC applied:
Is charge (CHG) LED on remote blinking? If not, then the charger does not recognize
the incoming AC being within acceptable limits. Measure the input AC voltage, it
should be / 20 VAC. Also, check that the VAC Dropout setting on the
remote is 80 VAC or less. If the CHG LED is blinking, the transfer relay should close
within 20 seconds and the unit should then begin charging. If the LED is on solid, the
transfer relay should already be closed and the charger should be charging.
Transfer relay closes, then opens and continues to cycle:
AC voltage is too low, or has transients that drop the AC voltage momentarily.
Change the VAC Dropout setting to 60 VAC and check for improvements. If the
cycling continues, back off the Charge Rate from 100% to 10%. This cycling may
also occur if the AC output of the inverter is connected to the inverter’s AC input.
Check for proper input and output AC wiring.
