WBM, together with the WRD display let you monitor the state of charge (SOC) of the battery of systems powered by renewable energy sources and implements appropriate controls to manage the battery in a wise manner maximizing its useful life.
The Kit consists of:
- 1 Western WRD Remote monitoring system for charge controllers with WESTERN BUS #N52830550099.
- 1 Western WBM SHUNT for Battery Monitor #N52830550098.
Western WRD Remote monitoring system for charge controllers with WESTERN BUS
WRD is a display and controller device that together with the proprietarybus WBUS is part of the WESTERN WRD SYSTEM, a complete and intelligent system for the production and storage of photovoltaic energy in stand-alone systems. The WESTERN WRD SYSTEM is a flexible and advanced stand-alone system with intelligent functions, recording of historical functioning data with remote control from the Internet (cloud). Up to 8 MPPT controllers WRMxxcanbe parallelized with adjustablecharging power up to 14kW and monitor the battery bank energy through the battery monitor WBM.
WRD is suitable for 12/24/48V systems with lead or lithium batteries. The system is modular as WRMxx controllers can be paralleled to increase the photovoltaic power. WRD has a proprietary control bus named WBUS to communicate with the various compatible devices, able to access all the parameters both for the display and for the management of the control functions. The simple user interface, with 128x64 display and 4 buttons, allows an immediate visualization of all the parameters: powers, voltages, charge and PV string currents, energy meters, data logger and events. From WRD all Setup settings can be made for each single WRMxx controller connected and/or WBM battery monitor. Through WBM is possible to manage contacts related to the charge state of the battery for the intelligent activation of the loads. The logger data is stored in the removable μSD on the front panel. Through the Ethernet connection it is possible to connect to the Internet cloud so that both the data of the logger and all the other functions become remotely and accessible with the portal WRD SERVER.

Western WBM SHUNT for Battery Monitor
WBM measures current, voltage, battery temperature and SOC through appropriate algorithms. These data are transmitted to the WRD which displays them on the display, stores them on the internal logger and transmits them on the remote logger. WBM can control the charge or discharge of the battery through its two alarm outputs. WBM is able to measure battery currents in the range of +/- 300A with high accuracy (+/- 0.1A) and with a minimum power loss (maximum 9W with a current of 300A); to obtain these characteristics the current is obtained by measuring the voltage drop on its internal resistance (shunt). To properly mount the WBM in your system, you must therefore connect the internal measuring resistance in series to the negative battery terminal.
