In a DC-coupled system a charge controller is connected to the photovoltaic system. The solar charge controller regulates the flow of energy into the battery and ensures, that the
battery receives sufficient charge. A battery inverter is responsible for inverting the DC current to AC current that can be consumed by AC loads on site. DC loads should be supplied
via the load output of the charge controller. It incorporates a LVD (low voltage disconnect) function, protecting the battery from the dangers
of deep discharge.
