E-xpert — battery monitor
Country: Netherlands · Model: E-xpert
E-xpert shunt-based battery monitors track battery condition in mobile and off-grid systems. They measure current up to ±9,999 A with 0–35 V input voltage, which covers 12 and 24 V banks. The display shows the remaining charge in percent and how many hours the present load will last.

Description
The line has three models, E-xpert Lite, Pro and Modular. Current is measured as the voltage drop across a shunt placed in the battery circuit, usually in the negative lead between the battery and all loads and chargers. The ± sign means the monitor counts both discharge and charge, so state of charge comes from the real amp-hour balance rather than terminal voltage. Battery voltage sags under load and misleads, especially on lithium batteries with their flat discharge curve, and amp-hour counting avoids that error. The display shows state of charge and remaining runtime. That tells the user how long the load will last before recharging.
How to choose
The first check is bank voltage within 0–35 V, which suits 12 and 24 V systems but not 48 V. Size the shunt by the peak current in the battery circuit including the inverter, since a 3,000 W inverter on 12 V, such as the PSI or SWI, draws hundreds of amps. Choose between Lite, Pro and Modular by the functions and mounting you need, and check their differences on the datasheet. For 48 V server and telecom systems a monitor with this input range does not fit, and battery status there comes from the DC system itself, for example the SEC-HCP over SNMP.

FAQ
What maximum current can the E-xpert measure?
Up to ±9,999 A through the shunt.
Which battery voltages does the E-xpert support?
The monitor input range is 0–35 V, enough for 12 and 24 V systems.
What does the E-xpert display?
Battery state of charge and remaining runtime.
Where does the E-xpert shunt go?
In the battery circuit, usually the negative lead, so the current of every load and charger passes through it. Otherwise part of the current is never counted.
Why is the E-xpert more accurate than a voltmeter on LiFePO4?
LFP voltage barely changes over most of the discharge, while the monitor counts amp-hours through the shunt and shows the real state of charge.
