<p>The photovoltaic system operating method involves supplying electric energy from both first and second groups (Q1,Q2) of photovoltaic modules (2) to a first direct current (DC) motor (5). Electric energy is supplied from a battery (31) to a second DC motor (11). The second DC motor is excited, such that the motor voltage of the second DC motor is less than the open-circuit voltage of the battery. The battery is discharged into the second DC motor. An independent claim is also included for a photovoltaic system.</p> |
