Besides offering an accurate state of charge indication, the Expert Modular will also help users how to get the best service life out of the battery bank. The service life of batteries will be negatively...
The Expert Modular is compatible with lead based and Lithium (LiFePO4) based batteries. The Expert Modular can monitor up to three battery banks. The inputs for battery bank 2 and 3 can also be configured for other purposes, like mid-point voltage measurement, key switch input or backlight control.

Expert Modular up and running. It assumes that the enclosed installation guide has been followed carefully and that the Expert Modular is powered up for the first time. After this the Setup wizard will start automatically. If the Setup wizard does not start and the Expert Modular will jump to the normal operating mode after power up, it has already been configured before.

Functions F2 and F3 (see chapter 6.2 and 6.3). After the Setup wizard has been completed, the Expert Modular will take a few seconds to analyze your battery and estimate the nominal battery voltage as well as the current State of Charge (%). The State of Charge readout will show a small animation while it is calculating.
Once the Expert Modular shows the estimated state of charge value, it is now ready for use! Over time, it will keep on learning your battery and the estimated state of charge will become increasingly more accurate. 3. NORMAL OPERATING MODE...

Step size: 100h Alarm properties The Expert Modular offers four independent configurable alarms. This offers great flexibility for the installer. Whether you wish to configure four completely different alarm types, or trigger an individual alarm on for example four different State of Charge values, there are almost limitless possibilities.

When the deviation falls below the Off value, this alarm will be deactivated again. For more information on midpoint voltage measurement and setup, please see appendix 1 in the online version of this manual, available at...
F5.5 Warning. Choose whether or not the active alarm is shown on the display (‘VIS.’) or an audible alarm (‘AUD’) will sound. The audible alarm will stop sounding when the alarm has been cleared, or when a key is pressed. When the audible alarm is not interrupted, the alarm interval will slow down automatically against time.
Auto hide parameter. The default setting will allow the bottom parameter to only show for 120 seconds after the Expert Modular has been accessed. This will keep the display clean under normal conditions, which might be preferred by less technical end users.

Unlocking the Expert Modular When you wish to unlock the Expert Modular, you will notice that menu name ‘LOCK’ has been changed to ‘UNLOCK’. This is an indication that the unit is currently locked. Using the same method as explained in chapter 8.1, you can access the unlock menu and start entering the previously...

Appendix 1: Measuring the midpoint voltage of a 24V or 48V battery bank Being able to measure the midpoint (or center-) voltage of a battery bank that contains multiple series connected batteries or cells, is an important feature that can save you a lot of money in case one of the batteries or cells is dying.
Page 32
The reason for this is that through the interconnected midpoints, one bad battery in a series string can damage all other batteries if not being monitored correctly. However, when decent midpoint voltage measurement has been applied and an alarm is triggered when the voltage difference is too large, the midpoints of the series strings are allowed to be interconnected.
Page 33
Practical information Typically, the midpoint deviation is smallest when the battery bank is not being charged or discharged. However, even with only healthy batteries in the series string, a temporary imbalance will occur: during the absorption charge stage when the battery bank is being deeply discharged ...
