WRM20 is a complete solution for off-grid PV systems, to supply power to road signs systems, lighting systems, small low voltage systems and for the recharge of batteries inside caravans or boats. Several programs of load management, selectable by the user, make WRM20 the complete solution in many applications i.e. to supply power to CCTV cameras that have to work only during the day, or for blinking light systems/road signs that have to work only during the night, or to supply power to lighting systems that have to work only for a certain number of hours during the night.
A wide display shows battery voltage, PV module charging current, output load current and other parameters. WRM20+ model allows to connect WRD display for remote control. Western CO. provides the communication protocol on this port so the user can implement his own device datalogger or remote control
