Off-grid power supply device for hybrid energy storage systems OFGSⓇ-H

Off-grid power supply device for hybrid energy storage systems OFGSⓇ-H

Switching not required (always powered type) for 'Always and In Case Free' - Towards a phase-free environment for 'Disaster Preparedness Without Preparation' OFGSⓇH Series.

The OFGS® (OFF GRID SWITCH BOX) series from Tsuruta Electric is a transformer and control/protection integrated switching panel/transmission system developed to maximize the use of solar storage batteries during both normal and power outage conditions. The OFGS®-H series is a constant power supply system designed for hybrid storage battery systems. During power outages and restorations, it allows for seamless power supply and autonomous operation without the need for manual intervention, thanks to the automatic switching mechanism of the dedicated transformer. This system fully utilizes the capabilities of hybrid PCS without the need to switch between grid (GRID) and off-grid (Off GRID), enabling the realization of corporate renewable energy initiatives such as BCP measures, phase-free operations, and RE100, while addressing installation conditions related to grid connection. It facilitates the construction of a storage battery system that provides clean energy through natural energy (solar power) and off-grid (independent of the power grid) supply, regardless of normal or emergency situations. By packaging "three-phase transformers" + "Scott transformers (for specific single-phase loads)" + "protection devices" + "control devices" into an 'all-in-one package', installation and construction time can be significantly reduced.
