Western WRM20+ 12/24V 20A MPPT Charge Controller with RS485 Port

Western WRM20+ 12/24V 20A MPPT Charge Controller with RS485 communication port

WRM20+ model is provided with a RS-485 communication port that implement WBus protocol and allows to connect WRD display by Western CO. for datalogger and remote control. Western CO. provides this communication protocol on this port so the user  can implement his own device  datalogger or remote control.
WRM20+ is a 20A charge controller for 12/24V batteries with the research of the maximum
MPPT point of the PV module. You can install also PV modules for on grid applications or
amorphous silicon type. Simple and intuitive, it is the complete solution for stand-alone PV sy-stems, remote houses, camper vans, boats, industrial applications, road signs, TVCC systems and much more.
WRM20+ is a complete solution for off-grid PV systems to supply power to road signs systems, lighting systems, small low voltage systems and batteries inside camper vans etc. This solar charge regulator has a research circuit for maximum PV module power (MPPT): regardless of the battery voltage and its charge status, WRM20+ makes the PV module work at its maximum power point, maximizing the energy that comes from the module and then loading into the battery.
Thanks to the WRM20+ controller you can install the cheapest PV modules used in grid connected systems, with a number of cells different to 36 or 72. WRM20+ detects the day/night status according to the PV module voltage; therefore it is not necessary to connect further sensors to the regulator. A wide display shows the working status of the solar charge controller via simple and intuitive icons and also displaying the values of the recharge current, battery voltage, energy produced by the PV modules, load current and energy consumption by the load.
