Main Data Screen Overview
The Engel Smart Battery Box’ informative LCD screen displays all the required information
regarding your charge process:
• Cycle (Charge, boost, float, discharge)
• Battery Voltage or net watts
• Battery Level Icon
• Battery Capacity %
• Hours remaining until fully charged (Time Tracker)
Time Tracker Technology
The Engel Smart Battery Box has the ability to calculate the battery capacity in real time
and predict the amount of time remaining until the battery is fully charged.
The tracking system can be recalibrated periodically to improve the accuracy. This is
done by charging the battery in to float cycle using the AC adaptor, discharging to 0% (at
a discharge rate of 60-70 watts) then recharging to float cycle again.
Changing the Screen Information
The net watts can be changed to battery voltage by pressing the down button for 1
second (Refer to page 4). By pressing the up button for 1 second the screen can be
changed back to net watts.
Please note positive net watts indicates power going into the battery and negative net
watts indicates power drawn from the battery.
Using the 240V AC Inverter
The AC socket is powered by an internal inverter that converts 12V DC to 240V AC with
a continuous power output of 300W. The inverter also has a USB 5V DC output socket
for charging cameras, MP3 players or SatNav units. To use the AC socket or 5V USB
socket the inverter on/off switch must be switched on and the main isolator switch
must be in the “on” position. The inverter is protected by a 30A fuse on the underside of
the lid. Do not connect high power appliances like a hair dryer or kettle to the inverter as
this may cause damage. Also this type of inverter cannot be used with fluoro lighting.
The inverter will start to sound a warning alarm once the battery voltage is getting
low and reaches 11V. At this stage the inverter should be switched off or the device
disconnected. If this is not done the inverter will switch itself off when the battery
voltage reaches 10.5V.
Inverter Warning Signals (Bi is short beep, BEE is longer beep)
Condition Warning Signal Cycle Shutdown Signal Cycle
Low Battery Alarm Bi Bi Bi (pause) BEE BEE BEE (pause)
Over Heating Alarm Bi Bi (pause) BEE BEE (pause)
Over Load Alarm Bi Bi Bi Bi Bi Bi Continuous beep
The inverter can be used outdoors but not in wet weather.
WARNING – DO NOT connect high power appliances like a hair dryer, iron, toaster,
heater, corded power drill or kettle to the 240V outlet as they greatly exceed the max
power output of the inverter and may damage it.
