Installation overview
5)
Blocking diode: prevents battery discharge to the PV module during the night, that is when the PV module has no
voltage.
6) Charging circuit with
maximum power point track of the PV module.
7)
Diverter circuit that charges the primary battery (battery 1) or the secondary battery (battery 2).
8)
Output charging control circuit that is always powered exclusively by the primary battery (battery 1)
Electrical connection
6)
Install WRM15 dualB in a dry and adequately ventilated place. Fasten on a non
to leave a space without obstacles of at least 10 cm in the proximity of the device to allow cooling by natural air
convection.
7) C
onnect in the following order: the load , the sensor for measuring battery temperature (supplied), PV module and
finally the primary battery (battery 1) as in pic. 2. At the connection of the battery the controller turns on and begins
to operate. Use appro
priate cable sections as indicated in pic.2. WRM15 dualB automatically recognizes the nominal
battery voltage, and adapt its operating thresholds.
8)
Connect the secondary battery (battery 2). One flash of LED battery 2 indicates that the secondary battery ha
recognized properly. If it does not, this means that the secondary battery is not recognized and will be never loaded.
It is not compulsory to connect the secondary battery so, if not connected, the WRM15 dualB will load only the
primary battery.
9) C
onnect the Bluetooth® modem to the controller and test the connection through the application on smartphone.
10)
Set the management program for the appropriate load to the application using the Bluetooth® connection on a
smartphone or tablet.
