Expert — battery monitor 12/24/48 V
Country: Netherlands · Model: Expert Lite / Pro / Pro-hv / Modular
The Expert shunt monitors count the charge and discharge current and show the state of charge (SoC) and remaining runtime for batteries of 20–10000 Ah. The four models of the range, Lite, Pro, Pro-hv and Modular, are powered from 7 to 70 V depending on the version and are used on boats, vehicles and off-grid systems.

Description
The Lite and Pro are designed for a 9–35 V supply, that is, for 12 and 24 V systems, the Pro-hv for 14–70 V and the Modular for 7–70 V, so the last two models can also be installed on 48 V banks. The voltage measurement error is ±0.3–0.5 % and the current error ±0.4–0.8 %. Such accuracy matters for LFP batteries with a flat discharge curve, where the state of charge can hardly be determined from voltage. The Expert Pro works with currents up to ±9999 A and the Modular up to ±600 A, and both account for discharge as well as charge. The Modular monitors up to 3 batteries at once, for example a starter battery, a service battery and a bow thruster battery. NMEA2000 and Bluetooth are provided in the range for sending data to a chartplotter or smartphone.
How to choose
Choose the model by the bank voltage, current and number of batteries. For a single 12 or 24 V bank the Lite or Pro with a 9–35 V supply is suitable, and the Pro is rated for a current up to ±9999 A. For 48 V you need the Pro-hv with a 14–70 V supply or the Modular with 7–70 V. When you need to monitor 3 batteries at the same time, the Modular with a current up to ±600 A remains.

FAQ
What battery capacity does the Expert monitor support?
The capacity is set within 20–10000 Ah, so the monitor suits both a small service battery and a large bank of an off-grid system.
How many batteries does the Expert Modular monitor?
The Expert Modular monitors up to 3 batteries, for example a starter battery, a service battery and a bow thruster battery, at a current of up to ±600 A.
Can the Expert monitor be installed on a 48 V system?
Yes, the Pro-hv is powered from 14–70 V and the Modular from 7–70 V. The Lite and Pro are designed for 9–35 V, that is, for 12 and 24 V.
How accurately does the Expert monitor measure current and voltage?
The current measurement error is ±0.4–0.8 % and the voltage error ±0.3–0.5 %. Counting ampere-hours through a shunt gives a more accurate SoC than an estimate from voltage alone.
Does the Expert monitor send data to a chartplotter?
The range provides NMEA2000 and Bluetooth interfaces, so SoC and remaining time can be sent to the onboard network or to a smartphone.
