Charge Controller MPPT 20A WESTERN Photovoltaic Camper Boat

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 caravans. This model of charge regulator has a circuit for the research of the maximum PV module power (MPPT): regardless of the battery voltage and its charge status, WRM20 works with the PV module in its maximum power point, maximizing the energy that comes from the module and then is loaded 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 from 36 or 72. WRM20 detects the day/night status according to the PV module voltage; therefore it’s not necessary to connect further sensors to the regulator. A wide display shows the working status of the regulator not only through simple and intuitive icons but also displaying the values of recharge current, battery voltage, energy production by the PV module, load current and energy consumption by the load.

Product Features

WRM-20 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. This model of charge regulator has a circuit for the research of the maximum PV module power (MPPT): regardless of battery voltage and its charge status, WRM-20 works with PV module in its maximum power point maximizing the energy that comes from the module and then loaded into the battery. Unlike PWM charge regulators that require PV modules with 36 cells for the recharge of batteries at 12V and PV modules with 72 cells for the recharge of batteries at 24V, thanks to WRM-20 controller this project restraint is no more necessary. With MPPT controllers you can install the cheapest PV modules used in grid connected systems with a number of cells different from 36 or 72. In addition you can use amorphous PV modules that normally are not suitable for PWM charge regulators. Several programs of load management, selectable by the user, make WRM-20 the complete solution in many applications i.e. to supply power to TVCC 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. WRM-20 detects the day/night status according to the PV module voltage; therefore it’s not necessary to connect further sensors to the regulator. A wide display shows battery voltage, PV module charging current, output load current and other variables.
