IoT Remote Display and Datalogger 12/24/48V
WRD is a display and controller device that together with the proprietary
bus 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 WRMxx
can be parallelized with adjustable charging 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.
