Photovoltaic system for generating current, has inverters, where each inverter has bypass lines for bypassing service sections, and high impedance resistors arranged at bypass lines

摘要

The system has two inverters (3) turned on over alternating current lines by a common automatic network isolating device (1) at electricity mains. The network isolating device has a measuring circuit (2) for measuring insulation resistances of solar generators (5) in comparison with earth, where the generators are attached to the inverters. Each inverter has bypass lines for bypassing service sections (4), and high impedance resistors (R3, R4) are arranged at the bypass lines. An independent claim is also included for a method for operating a photovoltaic system.
