WRM15 dualB is a device to charge up to two batteries from PV module.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.
Two versions of the controller are available, one called WRM15 dualB and
WRM15 dualB-E, which differ because the dualB version also implements the
load output and a USB port for charging smartphones, tablets or battery banks.
