  • Page 14: Utility Failure Operation

    4.2.3 Utility failure operation When the Utility is no longer within acceptable tolerances, the Battery will provide the DC power to the Inverter. The Inverter will maintain continuous AC power to the Load until the Battery Voltage reaches the lower limit of the Inverter operation capability.

  • Page 15: Automatic Bypass

    4.2.5 Automatic Bypass In normal operation, the Load is supplied by the Inverter. When the control system detects a fault in the Inverter, an overload condition or a short-circuit condition, the Automatic Bypass will transfer the critical Load to the Utility without interruption. When the Inverter recovers, or the overload or short-circuit condition is corrected, the Load will be automatically transferred back to the Inverter.

  • Page 16: Parallel System Operation

    PARALLEL SYSTEM OPERATION 4.3.1 Introduction to the parallel system Two or more equal power units can be paralleled to increase the output power (paralleling for capacity) or to improve the overall reliability of an UPS system (paralleling for redundancy). The outputs of parallel units are connected to a common power bus, and in normal operation the units connected on the parallel bus share the Load equally.

  • Page 17: Features Of Rpa Parallel System

    4.3.2 Features of RPA parallel system The SG Series 225 & 300 Parallel System is designed to provide a complete Redundant Parallel Architecture, and is free from common equipment. Not only the Inverters are redundant, but also the Bypass functions are designed with redundant modular concept.

    A parallel system with a Common Battery for two or more Rectifiers, requires a particular installation and adequate setting of some parameters, (accessible only through password), and can therefore only be done by a QUALIFIED ENGINEER from GE. Usually each Rectifier-Inverter Unit runs with its own Battery.
