Design & Build
This MPPT charger controller has a robust, installation-ready enclosure with a clean silver finish, contrasting black front and end sections, and blue-and-orange front graphics. The recessed LCD/control panel is neatly laid out and protected within a dark faceplate for a professional appearance. Visible ventilation slots on the sides and a rear cooling fan support airflow around the unit during operation. Integrated black mounting flanges with multiple fixing slots make the controller suitable for secure panel, wall or equipment-board mounting. At the connection end, the terminal area is clearly labelled, with a green temperature sensor connection visible alongside the solar, battery, DC load and RS485 interfaces.
