Powador-protect

Product catalog summary

Overview: Powador-protect is a voltage and frequency protection device designed for photovoltaic (PV) systems that connect to medium- or low-voltage grids. It serves as a central interface protection according to VDE-AR-N 4105 and CEI 0-21 standards, especially useful when interface protection tests are not feasible due to numerous string inverters or lack of test terminals.

Key Features:

Constant monitoring of grid voltage and frequency parameters, triggering disconnection if limits are violated.
Compatible with inverters from any manufacturer, with optimal performance when used with KACO new energy inverters.
Single-fault tolerance ensures safety functions remain intact even if a fault occurs.
Feed-in management capability, allowing remote-controlled power reduction for systems above a certain power threshold.
Manages signals from ripple control receivers for up to 31 inverters.

Technical Specifications:

Power Supply: 100 – 264 V AC, Rated Voltage: 230 V AC, Max Power Consumption: 2.5 W.
Measurement: Grid voltage range 0 – 300 V AC, Frequency range 40-70 Hz, Rated Frequency: 50 Hz.
Actuation: Max AC current 2.0 A, Max AC voltage 250 V, Max DC voltage 30 V.
Mechanical: Interfaces include screw terminals for measurement and switch contacts, LCD display, and control buttons.
Environmental: Operating temperature range -20 °C to +70 °C, Protection class IP20, Housing made of polycarbonate.

Installation and Use: Powador-protect is installed in the main distribution system, measuring voltage directly at the meter to account for voltage drops. It can be mounted on top-hat rails or wall mounts.

Compliance and Standards: Complies with VDE-AR-N 4105 and CEI 0-21 standards, with temporary protection according to German Medium Voltage Directives. Offers user-defined voltage and frequency adjustment options.

Grid management with Powador-protect. Technical data Powador-protect Powador-protect is a voltage and frequency protection device and a control unit for PV systems that feed into the medium- or low-voltage grid. If an interface protection test is not possible due to a large number of string inverters or lack of inverter test terminals, Powador-protect can be used as central interface protection according to VDE-AR-N 4105 and CEI 0-21. Powador-protect also offers the functionality for feed-in management. It evaluates potential free contacts provided by the control system of the distribution network...
