November 1 (Friday) 10:00 AM - 11:00 AM Announcement of the 6th webinar. "What are the key factors in adopting solar power and battery storage systems?" Registration is now open.

Switching unnecessary (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 switchboard/transmission system that integrates a transformer with control and protection, developed to maximize the use of solar battery storage both during normal operation and during power outages. The OFGS®-H series is a constant power supply system designed for hybrid battery systems. Even during power outages or restoration, 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 and off-grid modes, addressing challenges related to installation conditions for corporate renewable energy initiatives such as BCP measures, phase-free operations, and RE100. It enables the construction of a battery storage system that provides clean energy from natural sources (solar power) and off-grid (independent of the power grid) without distinction between normal and 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.

Space-saving design solar power generation system PPSC® series + SUNGROW PCS with integrated transformer and protection device on a PCS mounting platform.

The PPSCⓇ series of full self-consumption solar power generation systems now includes the RS series (backpack type) integrated with the power conditioner, enabling one-stop installation of the power conditioner, transformer, and protective devices. With transformer technology specifically designed for solar power applications, along with lightning surge protection and leakage current prevention features, it allows for 100% utilization of solar energy, enabling highly efficient energy generation with low standby power consumption. = Advantages of adopting the RS series = ■ Space-saving with PPSCⓇ series + power conditioner ■ Significant reduction in time previously spent on separate installation and construction of power conditioners, transformers, and protective devices. ■ No need for wall drilling work ■ Elimination of installation and logistics costs, as well as time loss in construction periods ■ Reduction in logistics costs due to decentralization ■ Voltage conversion ■ Leakage current prevention (prevents unnecessary operation of the permanent magnet on the cubicle side) ■ Lightning surge protection feature ■ High efficiency and low standby power ■ Specification of core materials (amorphous and electromagnetic steel sheets) is possible ■ Heavy salt damage resistance (optional)

Protech Engineering (Booth Number: 240) will be exhibiting at the "Hokkaido Construction Development Comprehensive Exhibition 2025," scheduled to be held on October 8 (Wednesday) and 9 (Thursday), 2025. On the day of the event, we will provide detailed explanations of the following disaster prevention products using models, panels, and various materials. ◆ Main Exhibited Products ◆ - Energy-absorbing rockfall protection fence / ARC Fence (model display) - Landslide debris protection fence / Slope Guard Fence Type LE (model display) - Pile-type (pile foundation) debris flow and driftwood countermeasure for non-flowing streams / Urban Guard - Avalanche prevention piles / Tri-Pile - Avalanche protection fence / Slope Guard Fence Type LS - High energy-absorbing rockfall protection fence / Macro Fence In addition, we will have a variety of materials on disaster prevention products developed independently by Protech Engineering, so we kindly invite you to visit our booth.

Profect Co., Ltd. will hold a seminar on October 3rd (Friday) themed around the IT Implementation Subsidy 2025 and our developed and sold production management system "TED." This year's IT Implementation Subsidy has seen a significant decrease in the acceptance rate compared to previous years. Many companies are struggling with the situation of having wanted to implement IT tools but being rejected. In this seminar, we will explain why the acceptance rate has dropped, the background behind it, and the key points for being accepted. Additionally, we will introduce our initiatives that have achieved a 100% acceptance rate so far this year and the reasons why our production management system "TED," registered as an IT tool, is chosen. To accommodate busy schedules, this seminar will be held in a hybrid format, allowing for both in-person attendance and online participation via Zoom. Please choose your preferred method of participation according to your convenience. If you are currently considering applying for the IT Implementation Subsidy or are interested in production management, we encourage you to join us. We sincerely look forward to your application.
