A storage battery that can be used safely for a long period of time
Safe long-term storage battery

Reliability for safe long-term use

This is a lithium-ion battery that uses iron phosphate as the positive electrode material. Compared to ternary lithium batteries that use cobalt, nickel, and manganese, it is safer and there is almost no risk of fire.
It is made of a material that can be used continuously with high input and output, allowing for safe long-term use.

Supports a variety of trial methods

Supports various usage methods required for industrial storage battery systems, such as self-generation and self-consumption, peak shifting, cutting, BCP measures, and electrical infrastructure projects. Fluctuation suppression is also possible.

A storage battery that can be used in a variety of ways
Storage battery connected to the network

Connecting to a network

Connecting to a network allows remote monitoring and operation, and the system can be further improved by using AI, etc.

Scalability

The string method can be used to meet high-capacity demands. There is no limit to the amount of capacity that can be installed in parallel.
Partial repairs can be made without stopping operation.
We provide a reliable support system, with complete backup support from inspection to battery collection after use.

Create the electricity that is indispensable to your life.
What you will get beyond that is a new energy life of "peace of mind," "comfort," and "savings."
This product's large-capacity, powerful system supports everything from everyday life to power outages.
Furthermore, since it is a full-load type, you can use electricity as usual even during a power outage.
It can also automatically store cheap electricity late at night and sell the surplus electricity during the day.
We propose a system that is ideal for the smart power generation life of the future.

  • 12kWh large-capacity storage battery, high output of up to 5.5kW This is a powerful household hybrid power storage system that uses a 12kWh large-capacity storage battery and can output up to 5.5kW.
  • Use electricity stored late at night during the day to reduce electricity bills. Use cheap electricity at night in a storage battery You can reduce your household electricity bill by storing cheap electricity at night in a storage battery and using electricity from a storage battery or solar power generation system during the day.
  • Safe even in times of disaster This is a full-load type that is safe even during power outages, so you can use high-load 200V equipment (IH cookers, air conditioners, etc.). This is a very reassuring system in these days of frequent natural disasters.
