Product Description

The produced energy can be used to power a local load (off-grid systems) or it can be fed into the public power-grid (grid-connected systems). As the PV generator output is direct DC and most loads and public grids generally accept only AC, PV inverters are used to perform the necessary DC-AC conversion. As the current and voltage output of a PV generator are not constant, the inverter must also adjust to the changes at its input circuit so that the maximum possible power is drawn from the generator. By way of an example, the amount of light available naturally contributes to the PV cells' current output, whereas the voltage output is inversely affected by the cell temperature. Between the PV panels and the AC grid are the so-called balance-of-system (BOS) components. These include the inverter, the interconnecting cables, wires, over-current and surge protection, earthing equipment and a means for switching and disconnecting different parts of the circuit. For example, the international standard IEC 60364-7-712 requires a means for disconnecting the inverter from both sides. Moreover, the standard specifically demands a switch disconnector to be provided on the DC side of the PV inverter. This allows the disconnection and reliable isolation of the inverter from all DC sources. Additional switch equipment can be used for disconnecting parts of the PV array, for system earthing or for switching possible energy-storage circuits.

Advantages

High breaking performance

A glass fibre reinforced polyester break chamber with an arc extinguishing system provides a patented safety disconnection system offering rapid extinguishing of the electric arc up to 1500 VDC and current interruption up to 800 A.

Remotely operated product

ASWICH PV are intended for use in photovoltaic installations and solar inverters. They can be remotely controlled via volt-free contacts, from either an external automatic controller or a switch.

Manual emergency operation

In addition to its motorised operation, the ASWICH PV also includes a manual operation facility, enabling the switch position to be changed directly on the device if required.
