Western WRM30+ 12/24V/48V 30A MPPT Charge Controller

WRM30+ is a PV charge controller for big off-grid systems. It is suitable for 12V/24V/48V systems with lead acid and lithium-ion batteries and it can handle a photovoltaic power up to 1.8kW.
WRM30 has been properly designed for industrial applications such as the power supplying of either TV/radio relays, road signs, or whole houses completely stand-alone.
WRM30 implements a research circuit for the maximum power of panel (MPPT): regardless of battery voltage and its state of charge, the charge controller makes always the PV module work at its point of maximum power maximizing the energy extracted from the PV module and charged into the battery. Charging is compensated in temperature.
Special feature of this product is the presence of two separated charging channels and, therefore, a double input for PV modules. This allows the management of two independent strings, for example in the case they are composed of modules with different features or exposed on two slopes, or, with identical strings, channels can be paralleled thus optimizing efficiency.
The load output can be activated according to several programs that can be selected by the user: load ON 24h/24h, load ON only during the day, load ON only during night, load ON during night for a number of hours from 1 to 16, and load ON at the end of the charge so to exploit all the exceeding energy.
WRM30+ detects the day/night status according to the PV module voltage; so it is not necessary to connect additional sensors to the controller.
It is equipped with a RS485 serial interface through which you can access all of the available functionalities.
WRM30+ has new functionalities and features: voltage of the PV modules up to 180V, derating curve, easy navigation of the menu and compatibility with WESTERN WRD SYSTEM (advanced monitoring and display system for high power MPPT systems.
