iii) Manual Backup with Battery Charger Function Enabled – (‘INT’ = ‘MBU’, ‘CHG’ = ‘ON’)
This is another commonly used setting on the unit. The charger function is enabled when AC Input
Source or Shore Power is available. When there is a blackout, the inverter will not turn On
automatically. It requires the user to manually turn on the inverter function when needed.

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 enabled. Inverter is disabled.
- Display shows battery voltage (14.2V), use or button to see DC Current charging
the battery, 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.
- is On indicates the charger is enabled and is charging the battery.
- icon indicates the charging stage of the battery.
- ‘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 green, it indicates battery is fully charged.
- If ‘Status’ indicator is flashing green, it indicates battery charging is in progress.
Note: In By-Pass Mode, the ‘Power’ button function is disabled in this stage. It cannot
be used to turn Off the unit.
When there is a blackout (AC Input Source or Shore Power is not available), unit will not provide AC
Backup as Inverter is disabled. Display remains On for 10 seconds with the following appearance:
- Display shows battery voltage (12.6V), use or , button to see DC Current (always
0A because charger is Off), AC Input Power (always 0W because Inverter is
disabled).
- icon indicates estimated battery capacity.
Note: Under this condition, Display and unit will turn Off after 10 seconds.
At any time, if an AC Input Source is detected, unit will switch back to By-Pass Mode
automatically in about 10 seconds. During the 10 second period, ‘Power’ indicator turns
On and ‘Status’ indicator remains Off.
- ‘Power’ indicator on indicates unit is On.
- ‘AC Output’ indicator is Off (AC Output is not available due to the inverter being set to
Manual Backup Mode – MBU).
- ‘Status’ indicator is Off.
If AC Output is required during a blackout, press and hold the ‘Power’ button for one second to manually
turn On 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: The ‘Power’ button can be used to turn the unit Off 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.
