Western Co. WRM15 dualB-E Charge controller MPPT 12 V, 24 V 15 A

WRM15 DualB is a device, which serves to charge up to two batteries via a solar module. It has been designed specifically for watercraft or motorhomes, using two batteries: The first for power supply to consumers on board and the second for starting the engine and its associated functions. The WRM15 dualB normally prioritizes charging battery 1 (on-board load) and then charges battery 2 (start-up process). In any case, the battery 2 is permanently monitored and is immediately charged if its voltage falls below the minimum voltage.
The WRM15 dualB is monitored by an application installed on an Android/iOS smartphone that connects to the device via Bluetooth Low Energy and allows to display the internal operating status and set some functions. Two versions of the controller are available: A WRM15 dual B named and another WRM15 dual B-E. They are different because the dual B version also offers more charging output and the USB connector for charging the batteries of smartphones, tablets and battery loops.
