PER 2V Meter Cabinets for Planned PV Systems

PER 2V Meter Cabinets for Planned PV Systems

PER 2V meter cabinets are designed for planned photovoltaic systems. They include an installation disconnect switch and can be adapted easily when a PV system is installed.

For generation plants and micro-sources, safety requirements call for a switching device (a mechanical switch or circuit breaker) in the meter cabinet. This is the so-called Installation Disconnect Switch, which electrically isolates the meter cabinet from the customer’s electrical installation (supply point). In our meter cabinets for generation plants je rotary switch with the same rated current as the cabinet.

All generation plants with an installed capacity up to 100 kW that can export to the distribution network must be capable of power control via an HDO receiver. Output is controlled at 0% or 100% and this function is used only in emergency situations. To enable this control, the cabinet must include an auxiliary relay and be wired differently from a standard meter cabinet.

By contrast, cabinets for standard consumption without a generation plant have the HDO receiver wired to control appliances, and do not require an installation disconnect switch. The cabinet PER 2V already includes an installation disconnect switch, but the cabinet’s wiring, particularly the HDO receiver, is still configured for standard consumption without PV or another generation plant or source. When a PV system is commissioned and the supply point becomes a generation plant, there is no need to add an installation disconnect switch or alter the power wiring; it is enough to reconnect the control wires from the HDO receiver and add an OR auxiliary relay.

Cabinets with installation disconnect switch are also recommended when you are only considering installing a generation plant or micro-source.

PER 2 cabinet overview

PER 2 – standard cabinet for supply points with two-tariff metering
PER 2S – cabinet for supply points with two-tariff metering and Sterminals under a separate unsealed cover
PER 2V – cabinet for supply points with two-tariff metering and an Vinstallation disconnect switch under a separate unsealed cover
PER 2F – cabinet for supply points with two-tariff metering and an installed Fphotovoltaic system and an installation disconnect switch under a separate unsealed cover

PER 2V includes an installation disconnect switch as standard, as required for metering supply points with a generation plant or micro-source. The cabinet meets the latest distribution company requirements for metering without PV and can be easily adapted for metering with PV.

Cabinet approved for ČEZ Cabinet approved for EG.D (formerly E.ON)

PER 2V cabinets comply with the connection requirements of ČEZ Distribuce and EG.D (formerly E.ON Distribuce). The cabinets are based on the meter cabinet in the Modul configuration and are designed for two-tariff metering up to In 63A. Cabinets are available for currents up to 40 A and 63 A, in three-phase versions, for wall installation or as complete pillars.
