The TR 0301 U controller was specially developed for the North American market based on the TR 0301 basic controller. With its special certification (ETL label) from a Nationally Recognized Testing Laboratory (NRTL) in the US, the controller meets the safety standards and minimum requirements of the North American market.
A feature of the TR 0301 series of controllers is the animated graphic display, which offers a complete visualization of the solar energy system's operating status and solar circuit.
