ii) Automatic Backup with Battery Charger Function Disabled – (‘INT’ = ‘ABU’, ‘CHG’ = ‘OFF’)
This is a setting when a second Battery Charging source is use and the unit’s built-in AC Charger
function is disabled at all times. Please note that a second battery charging source is required to
charge the battery. The Inverter will automatically turn on when AC Input source or shore power is
interrupted. This provides smooth, uninterrupted AC power to the load. The inverter is in standby
condition.

When AC Input Source or Shore Power is available, unit is running in By-Pass Mode. AC Output is
getting the power from the AC Input Source or Shore Power. Charger is disabled. Inverter is in standby
condition.
- Display shows battery voltage (12.5V), use or button to see DC Current (always
0A because charger is disabled), AC Input Power.
- is On indicates AC Input Source is in use.
- is On indicates AC Output is getting the power from AC Input source.
- icon indicates estimated battery capacity.
Note: When this setting is used, AC Charger is disabled. A separate Battery Charger or
other battery charging source is required to charge the battery.
- ‘Power’ indicator on indicates unit is On.
- If ‘AC Output’ indicator is On, it indicates the AC Output Switch is turned On (AC is
available at the output socket and the output hardwire terminal).
- If ‘AC Output’ indicator is Off, it indicates the AC Output Switch is turned Off (AC is
not available at the output socket and the output hardwire terminal).
- Press and hold ‘Escape’ button for 5 seconds to toggle AC Output Switch On and Off.
- ‘Status’ indicator is solid green indicates unit is running in By-Pass Mode.

turn Off the unit.
When there is a blackout (AC Input Source or Shore Power is not available), unit is running in
Inverter/Battery Mode. Unit has automatically switched to getting AC Power from the inverter.
- Display shows battery voltage (12.8V), use or button to see DC Current
discharged from battery, AC Output Power.
- is On indicates inverter is providing AC Power.
- icon indicates estimated battery capacity.
- ‘Power’ indicator on indicates unit is On.
- If ‘AC Output’ indicator is On, it indicates AC Output Switch is turned On (AC is
available at the output socket and the output hardwire terminal).
- If ‘AC Output’ indicator is Off, it indicates AC Output Switch is turned Off (AC is not
available at the output socket and the output hardwire terminal).
- Press and hold ‘Escape’ button for 5 seconds to toggle AC Output Switch On and Off.
- If ‘Status’ indicator is solid amber, it indicates inverter is running.
- If ‘Status’ indicator changes to flashing amber, it indicates AC Input Source is
detected and will switch back to By-Pass Mode shortly.
Note: In Inverter/Battery Mode, the ‘Power’ button can be used to temporarily turn the
unit Off to save battery power if AC Output power is not required. When AC Input Source
or Shore Power returns, unit will automatically turn On and run in By-Pass Mode again.
