4.3. Configuration: WRD + WBM + WRMxx
This configuration is used in a stand-alone system where you want to monitor the quantities of production,
consumption and accumulation (Pic.A4 and Pic.A5).
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.
Considering that, in CONTROLLER mode, the charge made by the WRMxx is already controlled through the WBUS,
it is not necessary to exploit the 'Charge' contact of the WBM.
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 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.

4.4. Configuration: WRD-Leonardo Datalogger + Leonardo Off-Grid GE

The WRD-Leonardo Datalogger can be combined with a Leonardo Off-Grid GE inverter to add remote monitoring
of the system, and other services described in the setup menu 8.3 (Pic.A6 and Pic.A7).
