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.
4.1. Configuration: WRD + WBM
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.
4.2. Configuration: WRD + WRMxx
This configuration is used in a stand-alone system where you want to mainly monitor the energy production
(Pic.A2 and A3).
The WRMxx controllers, which can be paralleled up to a maximum of 24, are used to charge the battery. (see
dedicated product manual for more details).
The WRD allows to collectively configure 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 WRMxx: Load/OUT output (where available) 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.
