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.

8.2. Configuration: WRD + WRMxx
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.
