Design & Build
This MPPT solar controller has a robust, professional-looking enclosure in a silver-grey finish with contrasting black front and lower panels. The front-mounted blue-backlit LCD is neatly set into a dark control panel and paired with four clearly marked buttons for menu navigation and adjustment. Purpose-made black mounting brackets run along both sides, with multiple slots and holes visible for secure installation against a wall or inside a solar equipment cabinet. Ventilation perforations on the sides and a protective fan grille on top complement the smart cooling design. At the lower connection area, clearly labelled terminals for solar panel, battery and DC load wiring are visible, alongside the RS485 port and a marked temperature sensor connection.
Ideal For
A practical choice for home solar systems, backup power banks, off-grid houses, farms, workshops, security installations, small business solar projects and solar equipment resellers. Its automatic multi-voltage capability makes it particularly useful where 12V, 24V or 48V battery configurations may be required, while the DC load connection adds convenient control within compatible standalone solar systems.
