CAUTION: As the inverter is transformer-free, neither positive nor negative
polarities of PV arrays shall be ground connected; otherwise, it may present
a risk of inverter failure. In a photovoltaic energy system, all metal
components that are non-current-carrying, e.g. brackets, combiner boxes,
distribution boxes, inverter boxes, shall be grounded.
