Design & Build
This MPPT solar charge controller has a professional silver-and-black cabinet-style design that looks at home in a dedicated solar room, electrical enclosure or technical workspace. The clean silver front panel is finished with bold MPPT branding and a centrally positioned black control panel, where the blue-backlit LCD and round navigation buttons are easy to access. Visible ventilation grilles run along the side and rear sections, while the rear view shows three fan assemblies behind protective guards. Multiple circular cable-entry points are also visible at the connection end, helping create an organised installation layout.
Ideal For
Ideal for commercial solar installations, farms, workshops, warehouses, lodges, telecom backup systems and large residential off-grid or hybrid battery banks.
