Product catalog summary
Product Overview
The WRM15 dualB is a device designed to charge up to two batteries from a photovoltaic (PV) module, specifically for use in boats or campers. It prioritizes charging the first battery, which powers on-board services, and then manages the second battery for engine starting. The device continuously monitors the second battery and initiates charging if its voltage drops below a minimum level.

Monitoring and Control
The WRM15 dualB can be monitored via an application on Android/iOS smartphones, connecting through Bluetooth Low Energy. This app allows users to view the device's operating status and configure certain functionalities.

Versions
There are two versions of the controller: WRM15 dualB and WRM15 dualB-E. The dualB version includes additional features such as load output management programs and a USB port for charging mobile devices.

WRM15 dualB / WRM15 dualB-E-1

dual battery bluetooth user interface Descrizione prodotto Product description WRM15 dualB è un dispositivo in grado di caricare fino a due batterie da modulo fotovoltaico. È appositamente progettato per essere impiegato a bordo di imbarcazioni o camper dove si hanno due batterie: la prima dedicata ad alimentare i servizi di bordo e la seconda per l’accensione del motore e servizi motore. Il WRM15 dualB normalmente dà priorità alla carica della batteria 1 (i servizi di bordo) e in seguito gestisce la batteria 2 (avviamento). La batteria 2 è comunque costantemente monitorata e, qualora la sua tensione scenda sotto un certo livello di tensione minimo, entra subito in carica. Il WRM15 dualB è monitorato tramite un’applicazione installata su smartphone Android/iOS che si connette tramite Bluetooth Low Energy al dispositivo e permette di visualizzare lo stato di funzionamento interno e di impostare alcune WRM15 dualB is a device able 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 services 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. WRM15 dualB is monitored through an application installed on Android/iOS smartphones that connects via Bluetooth Low Energy to the device and allows to visualize the operating status and set some of its functionalities. Two versions of the controller are available, one WRM15 dualB est un dispositif capable de charger jusqu’à deux batteries à partir d’un module photovoltaïque. Il est spécialement conçu pour être utilisé à bord des bateaux ou des caravanes où il y a deux batteries; la première est destinée à alimenter les services à bord et la deuxième à démarrage des moteurs. Le dispositif WRM15 dualB donne normalement priorité à la charge de la batterie 1 (services à bord) puis il gère la batterie 2 (démarrage) La batterie 2 est quand même constamment suivie et si sa tension descend au-dessous d’un certain seuil de tension minimum, elle entre immédiatement en charge. Le dispositif WRM15 dualB, est surveillé grâce à une application installée sur smartphone Android/ iOS qui se connecte par Bluetooth Low Energy au dispositi
