PV charge controller for dual battery

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

services) and then manages the battery 2 (starter). Battery 2 is still constantly

monitored and, if its voltage drops below a certain

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

connected to the board system .

WRM15 dualB implements a charging circuit MPPT and step

guarantees the maximum power charging from the PV module with any module

that has a maximum power voltage (Vmp) higher than the battery vo

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.
