Western Co WRM15 dualB Benutzerhandbuch Seite 15

WRM15 dualB is a device to charge up to two batteries from PV module that
powers and controls the load connected to its output. It is specially designed for
application on boat or camper where there are two batteries: the first one is for
feeding the on-board service and the other for starting the engine and engine
services. WRM15 dualB normally gives priority to the battery 1 (on-board
services) and then manages the battery 2 (starter). Battery 2 is still constantly
monitored and, if its voltage drops below a certain minimum voltage level, it
starts to charge.
To guarantee the charge of both batteries without running the engine both
during rest periods with passengers on board and during the parking period
without people on board, it is advisable to size properly the PV module
connected to the board system .
WRM15 dualB implements a charging circuit MPPT and step-down type, which
guarantees the maximum power charging from the PV module with any module
that has a maximum power voltage (Vmp) higher than the battery voltage and is
within maximum voltage limits (Voc) under 100V.
WRM15 dualB is monitored through an application installed on Android / iOS
smartphone that connects via Bluetooth® to the device and allows to visualize
the operating status and set some of its functionalities.
