Characteristics

ZGR PCS 4500 is a three-phase charger with the latest bidirectional control technology. Thanks to its different operating modes, this equipment offers grid operators a comprehensive tool for more flexible energy distribution by regulating power, voltage and frequency,guaranteeing the availability of the electrical grid.

In addition, it has a “Black Start” function, increasing the manageability of energy within the installation. Its design for outdoor use and extreme temperature conditions makes it the perfect solution for large-scale storage projects.

Operational modes: Frequency control; Black-Start (island mode); Active energy reserve; Voltage control; Active / Reactive power control; Inertia emulation.
Quick response to set point changes.
Wide range of working temperatures, from -20 ºC to +60 ºC.
Scalable, parallel equipments.
AC protections: Short-circuits and overcharges; Overvoltages and low voltages.
DC protections: Short-circuits (fuse); Overvoltage.
AC and DC breaker integrated.
Remote monitoring via Web Server.
Communication standard: TCP/IP.
Other communication standard on demand: SNMP, IEC 104...
