REMOTE DISPLAY FOR WESTERN WRD SYSTEM

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

1. GENERAL DESCRIPTION

Pic.1 WESTERN WRD SYSTEM with WRM30 +

In WESTERN WRD SYSTEM, WRD is the coordinator and can work in two modes: Viewer or Controller.

1.1. Viewer

By setting in the setup menu 8.4 WRD -> Oper.Mode: 'MONITOR': you get the View mode.

In this mode, the WRD does not control the charging and discharging of the system, but takes care only of displaying the

parameters of the connected devices, can change the setup settings of the slaves, collects data and remotely displays

them in the cloud. The various devices autonomously perform their main functions independently from the WRD.

1.2. Controller

By setting in the setup menu 8.4 WRD -> Oper.Mode: 'CONTROLLER': you get the Controller mode1.

In this mode, the WRD adds a control over the devices, dynamically modifying some parameters in order to optimize the

energy management of the entire system and ensure compliance with the battery parameters.

The operating mode of the WRD in menu 2.0 can be recognized from the indication in the battery graphics (§ Main

screens).

2. CONNECTIONS AND INSTALLATION

In the appendix (Pic. A1, An) the system connections are shown for the various possible configurations.

For its functioning the WRD uses the 12/24 / 48V system power supply and the connection WBUS which is physically an

RS485 bus, while the RJ45 Ethernet connection to the Internet cloud is optional.

The WESTERN WRD SYSTEM must be configured by setting to each WRMxx controller a unique address: from 1 to 32,

while the WBM already has a fixed address (33) as in the case of connection with a Leonardo (34).

2.1. Installation procedure

1) To install the WRD in a dry place, there are two fixing options: from the panel and with frame (Pic.4)

2) At the back you can access the electrical connections (Pic.4). Both the power connection and that of the WBUS are2

of a removable clamp type, easy to wire. Connect the cables correctly, if the power supply comes from the battery, it

is recommended that it is under the use of a fuse (0.5A) for cable protection. Finally, if it is used, also connect the

Ethernet cable.

3) Once all the connections have been made, power up the system. The WRD turns on and starts to function.

4) Now run the system configuration settings that will be required.

At the menu: 8.0 WBUS CONFIG. you can use the 'AutoConf.' command for simplicity, or you can make address

settings manually.

At the menu: 7.1 DATE / TIME you set the clock and time zone (Timezone).

At the menu: 7.0 SYSTEM you make system settings. The correct profile must be selected, corresponding to the

battery features (an incorrect choice could lead over time to damage the battery itself).

1 It is recognizable if a WRM30+ is remotely controlled (by WRD) if, on the WRM30+ display, the battery contour flashes every ~3sec.

2 The WBUS has the RS485 as its physical bus, so the two poles A and B must be connected correctly, while the GND pole should be left disconnected.

Depending on the current hardware, the configuration must be set on the WRD. This operation is performed on the

menu: 8.0 WBUS CONFIG. where the addresses of the devices connected to the device must be specified WBUS to

facilitate the operation an auto configuration command is available that detects the connected hardware.

Depending on the configuration set, the WRD displays the information and can execute its algorithms using the

available resources. The screens for each configuration are described below.

2.3. System Setup

In the menu: 7.0 SYSTEM the system settings are executed, the list of parameters changes according to the current

configuration. Detailed explanations are described in the chapter Configurations.

2.4. Date Time Setup

In the menu: 7.1 DATE / TIME you set the system clock and the time zone (Timezone). It is important to correctly set

this last parameter with the Timezone of the place where the system is located, so that the remote clock can be

updated correctly.

2.5. Data Logger Setup

In the menu: 7.2 DATA LOGGER you can enable the data logger by setting the minutes for the sampling parameters:

3. MENU NAVIGATION

Navigating through the various screens is very simple and intuitive. The WRD has two display environments (Pic.2):

-the main environment MAIN, consisting of six screens where the operation of the system is monitored;

-SETUP setting environment, consisting of 6 screens + 5 in ADV. SETUP where the settings for the operation are

set.

In the MAIN environment, the UP and DOWN buttons are used to scroll through the screens from 1.0 to 6.0,

the ENTER button accesses any submenu. Pressing the UP / DOWN buttons simultaneously for 1 sec. you

access the SETUP environment. Here, it is always repeated with the same UP or DOWN buttons, the scrolling of

the screens from 7.0 to 7.5. To return to the MAIN environment use the ESC button pressed for 1 sec.

To enter ADV. SETUP select the "Advanced Setup" item on the 7.5 OTHERS screen, press the UP botton so that "-->"

appears and then press the OK button for 1 sec.

It is possible to enter the EDIT mode (Pic.3), where it is

allowed, to modify the parameters by keeping pressed the

EDIT button for 1 sec. Entry into the EDIT mode is

visible on the display by the presence of the cursors on the

modifiable parameter. For editing are used the /

INC/DEC buttons, press the SELECT button to change

the value. For save the changes the button SAVE must

be kept pressed for 1 sec.

The WRD, through the Internet connection and IoT technology, communicates with the remote server and transmits

operating data. By registering and logging into the WRM MONITOR client web interface, it is possible to interact with

the system by changing its settings and, at the same time, monitor its own energy system.

In particular, the user has access to the following features:

Monitoring of the data sent by the system in real time: values of power produced, absorbed/taken from the

battery and consumed by the load, the state of charge of the battery and any alarm status.

Visualization of graphs, counters and indicators related to system statistics: trend of all the typical values of the

system, such as voltages, currents and powers. Possibility to select the display time period.

Reports of events related to the system, such as alarms or useful information.

Specific information of the system installed (type, capacity and battery voltage, device firmware versions).

8. CONFIGURATIONS

8.1. Configuration: WRD + WBM

8.1.1. Description

This configuration is used in a plant where you want to monitor the energy flow of the battery (Pic. A1). The WBM

battery monitor must be connected to the negative battery terminal and provides for the calculation of the

incoming and outgoing energy. (See dedicated product manual for more details).

WRD allows configuring the WBM in the Setup menu 7.0 or 8.1:

Select the correct profile according to the type of battery.

Select the battery capacity (Ah) correctly, so that the WBM can correctly calculate the State of Charge (%)

of the Battery.

Set the thresholds for the two contacts controlled according to the State of Charge (%) of the Battery.

The 'Discharge' contact can be exploited to control a device capable of disabling the load, thus determining the

maximum discharge depth within which the battery will cycle. This contact also intervenes in case of protections:

overcurrent, over temperature and under voltage.

With the 'Charge' contact, normally, is controlled a device capable of disabling the charge as it intervenes in the

event of protections: overcurrent, over temperature and overvoltage.

Setting the thresholds for the 'Charge' contact it can also be controlled according to the SoC in case some

applications require it.

8.1.2. Main screens

In the following picture are described the graphic used in the various screens of the main menu.

Take into account the notes shown in the pictures.

8.2. Configuration: WRD + WRMxx (1 ..8)

8.2.1. Description

This configuration is used in a stand-alone system where you want to mainly monitor the energy production

(Pic.A2).

The WRMxx controllers, which can be paralleled up to a maximum of 8, are used to charge the battery. (see

dedicated product manual for more details).

The WRD allows to collectively configuring the most common parameters of all the WRMxx in the Setup Menu

7.0, while it performs this individually in the Setup Menu 8.2.:

Select the correct profile according to the type of battery.

Select appropriately the setting of the Load output

Set the Low Battery threshold for the output Load.

- With the WRM30+: Load output can be exploited with setting 'SurPlus' to control or directly feed a load when

the battery is charged and there is still energy from the PV modules so we have an excess of energy that in this

way can be re-used.

8.2.2. Main screens

In the following picture are described the graphic used in the various screens of the main menu.

Take into account the notes shown in the pictures.
