Design & Build
This inverter has a substantial black-and-silver cabinet form with a clean, professional finish suited to a dedicated power room, utility area or solar equipment installation. Its front face is clearly laid out, combining a blue-backlit LCD display, indicator lights, control buttons and a large lower ventilation grille. The rear panel shows organised battery input, AC input and AC output connection areas, along with separate switches for straightforward system access. At approximately 760 x 430 x 830mm and 90.7kg, this is a robust floor-standing unit; the four fitted castor wheels make it easier to position during installation or maintenance.
