TSURUTA ELECTRIC CO., LTD. List of Products and Services

■ DC-Link 48kWh / B-Innovation Co., Ltd. ■ The benefits of introducing a storage battery are clearly visible when comparing power consumption vs. power generation in a graph. Especially during the solar season from May to October, solar power generation + storage battery = significant reduction in electricity costs with stored electricity. ■ Easy introduction and clear explanation of introduction benefits ■ You can easily understand the differences in operation of solar power generation before and after introducing a storage battery, and realize "So that's how it is!" Please feel free to contact us! 01 | A simple design that only charges from solar power generation. 02 | Can be connected to all PCS within the voltage range (DC 439.5 to 532.5V). *1 03 | Capable of outputting both single-phase and three-phase. 04 | Does not control the storage battery, but utilizes output control from the power conditioner to achieve self-consumption. 05 | Direct charging and discharging of direct current for high efficiency. Conversion efficiency of over 95%. 06 | Can be retrofitted/installed into existing self-consumption systems. (Refer to configuration example: connected between the power conditioner and solar panels) *1 Please feel free to contact us for compatible PCS manufacturers.

The OFGS® (OFF GRID SWITCH BOX) series from Tsuruta Electric is a transformer and integrated control and protection switchboard developed to maximize the use of solar and industrial storage batteries during both normal and power outage conditions, ensuring the protection of solar power generation equipment and enabling a safe electricity supply. This product, specifically designed for industrial storage battery systems, simplifies design and construction by packaging "three-phase transformers" + "Scott transformers (dry-type Scott transformers)" + "protection devices" + "control devices" into an "all-in-one package." It completely isolates the power conditioner (PCS) and cubicle (system/power), protecting power generation facilities and factory lines, while also improving power generation efficiency. Additionally, options such as compliance with fire prevention regulations and measures against salt damage are available. During power outages, users can choose between two types of switching to off-grid mode: "manual switching" or "semi-automatic switching."

The PPSC series of solar power generation allows for power procurement independently, even without electricity from the power company or fuel. It efficiently utilizes the solar energy generated. In the event of natural disasters such as earthquakes and floods, as well as conflicts, terrorism, or unexpected crises, it is not an exaggeration to say that preventing business shutdowns and quickly restoring operations to minimize the impact on the business is a lifeline for companies. Implementing BCP measures tailored to the company is crucial for protecting employees' lives during emergencies like natural disasters, reducing damage as much as possible, and quickly resuming business operations. It is important to prepare with awareness for securing power sources for disaster situations and restoring power within approximately one week. Not only does this facilitate early business resumption, but it also enables power sharing during disasters within the local community. By integrating "PPSC Transformer" + "Protection Devices" + "Control Devices," the self-consumption type solar power generation PPSC simplifies equipment installation and can build a self-consumption system according to installation space and purpose, even in harsh conditions such as salt damage. During power outages, power is supplied from solar generation, and surplus electricity is stored in batteries. For a battery system that can be used even at night, please refer to the OFGS series.

The SCOTT transformer series is a product specifically developed for solar power generation systems that use industrial three-phase storage batteries or PCS with three-phase autonomous operation functionality. It features high-efficiency transformers available in various capacities, and the integration of "transformer + protective equipment" tailored to the installation environment significantly reduces space and construction time. Additionally, it is possible to customize by combining a switching panel (grid/off-grid switching panel) necessary for autonomous operation. Furthermore, a power analyzer enables real-time monitoring and optimization of energy usage for control management. We offer comprehensive engineering proposals for building BCP measures and optimizing the operation of solar power generation systems. SCOTT System ■ Converts three-phase to single-phase (converts 202V power to 100V lighting and 0-100V) ■ Equipped with lightning surge protection ■ High efficiency and low standby power ■ Uses highly corrosion-resistant steel plates ■ Long-term warranty of 10 years free and 20 years paid

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.
