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.
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. The international standard IEC 60364-7-712 requires a means for disconnecting the inverter from both sides, specifically demanding a switch disconnector on the DC side of the PV inverter.
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.
Designed for photovoltaic installations and solar inverters. They can be remotely controlled via volt-free contacts, from either an external automatic controller or a switch.
In addition to its motorised operation, it includes a manual operation facility, enabling the switch position to be changed directly on the device if required.
