Design & Build
This MPPT solar charger controller has a sturdy, box-style metal housing in a clean silver-grey finish with contrasting black end panels. Blue and orange MPPT branding gives it a professional technical appearance, while the recessed black control panel protects and frames the LCD display and buttons. Integrated black mounting flanges on both sides feature multiple slots and holes for secure surface mounting. Side ventilation perforations and a rear-mounted cooling fan with a protective metal grille are clearly visible, helping to support airflow around the unit. Green terminal blocks create a clear visual distinction between the wiring area and the controller body.
Ideal For
Ideal for off-grid homes, backup-power installations, small business solar systems, farms, workshops, security installations and remote solar working stations. It is especially well suited to buyers who need a dedicated MPPT charger controller between their solar panels and battery bank, including systems that use an inverter for AC power. The DC load terminals also make it a practical central control point for compatible DC-powered loads within a solar installation.
