Outdoor photovoltaic systems

The PV system diagram consists of two parts - the AC side and the DC side. There is an inverter between these parts, which is the center piece of the system and its function is to convert the DC power generated by the PV modules into AC power that can be supplied to the distribution system or consumed as part of an autonomous system. The standard HD 60364-7-712:2016 requires the installation of surge protection devices on both the DC and AC side. The HLSA / HSA PV series of surge protection devices for photovoltaic systems in Y connection is equipped with a gas discharge tube – this ensures zero residual (leakage) current through the PE conductor and the resistance to the earth connection of the working conductor. These surge protection devices fully comply with the IEC 61643-32:2017 standard, which defines the conditions for the correct selection of a suge protection device for various applications.
