• Power distribution and control panels

In-house power generation with a fully self-consumption solar power system enables BCP measures, significantly reducing electricity costs during normal times and providing power supply during outages and emergencies.

The PPSC series of solar power generation allows for power procurement independently, even without electricity from the power company or fuel. It effectively utilizes the solar energy generated without waste. 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 interruptions and quickly restoring operations to minimize the impact on business is a lifeline for companies. Implementing BCP measures suited to one's own company is crucial for protecting employees' lives during emergencies like natural disasters, reducing damage as much as possible, and swiftly 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 allows for power sharing during disasters within the local community. By integrating "PPSC Transformer" + "Protection Devices" + "Control Devices," the PPSC self-consumption solar power generation system simplifies installation work and can be configured for self-consumption according to installation space and purpose, making it suitable for harsh conditions such as salt damage. During power outages, power is supplied from the solar power generation system, and surplus electricity is stored in batteries. For a battery system that can be used even at night, please refer to the OFGS series.
