The E-Xpert Pro selectively displays voltage, charge- and discharge current, consumed amphours, remaining battery capacity and time remaining of your battery bank. Using a clear backlit LC Display and an intuitive user interface, all parameters can be recalled with just a button press. A second battery input is also provided to monitor an auxiliary battery.

Defining the amount of energy available in a battery is a complex task since battery age, discharge current and temperature all influence the actual battery capacity. High performance measuring circuits, along with complex software algorithms, are used to exactly determine the remaining battery capacity. A new shunt selection feature enables the E-Xpert Pro to measure currents up to 10,000Amps.

The E-Xpert Pro is equipped with an internal programmable alarm relay, to run a generator when needed or to turn off devices when the battery voltage exceeds programmable boundaries. The E-Xpert Pro comes with a very clear installation and operating instruction manual.

**IMPORTANT** - The TBS installation manual shows the high voltage traction pack going to chassis ground. THIS IS NOT SAFE AND SHOULD NOT BE CONNECTED IN THIS MANNER. Keep the shunt located between the battery pack and the controller (or controller and motor) but never connect to the negative post of the auxillary 12V battery or chassis.

Shunt 50mV
shunt

A shunt is a resistor that is wired in series with your load allowing you to monitor the amperage in your system.
     
     
     

USB Communication Kit
expert pro communication kit

The E-Xpert Pro USB Communication kit contains a fully isolated interface box, an e-xpert connection cable, an USB interface cable, the "Dashboard" Windows software and a clear installation guide. The complete kit enables you to control, readout and configure the e-xpert pro from your Windows PC. Another possibility is to use the PC as a datalogger to record all measured parameters for further analysis.

Prescaler Kits
expert pro 5:1 prescaler

The E-Xpert pro 1:5 prescaler kit (both with built in dc-dc converter 'active' and without 'passive') extends the input voltage range of the e-xpert pro to enable implementation in 48VDC up to 120VDC battery systems (maximum input voltage is 175VDC).

The E-Xpert Pro passive 1:5 prescaler kit extends the input voltage of the E-Xpert Pro display to 350VDC max.

Alarm Output
Expander Kit
expert pro alarm output expander

The e-xpert pro Alarm output expander kit, expands the number of available alarm relay contacts from one to four. So instead of assigning all alarms to the internal alarm relay of the e-xpert pro, one can now choose to assign different alarms to three additional external alarm relays. This enables the possibility, to for example assign a low voltage alarm to the internal alarm relay and a high voltage alarm to one of three external alarm relays.

The Alarm output expander kit greatly increases the versatility of the e-xpert pro in more complex battery systems.
