<p>The method involves supplying an inverter (3) with energy from an additional energy source connected in parallel with input terminals (2) of the inverter, where the additional energy source is an electrical energy storage device i.e. lead battery, operated independent from a primary energy source (Q1). Frequency, phase relationship and output voltage of the inverter supplied from an additional direct current (DC) energy source is adapted to frequency, phase relationship and output voltage of a public power grid (7). The primary energy source is connected to the inverter after adaptation. An independent claim is also included for an apparatus for setting up synchronization to a power grid of an inverter having a photovoltaic generator as a primary energy source.</p> |
