We provide a low-cost, highly safe, and environmentally friendly system that enables resource recycling.

The lead-acid battery system soldam is a low-cost, highly safe home lead-acid battery system that uses 100% recyclable lead batteries.
This lead-acid battery system is installed between the solar panels and the power conditioner, and acts like a dam, blocking the electricity generated by the solar power generation system during the day and releasing it at night, allowing the electricity to be used without waste. Lead-acid batteries that have reached the end of their life can be reused and recycled as storage batteries that use recycled lead, allowing for resource circulation.

 

By utilizing lead-acid batteries, which have a low environmental impact, and by popularizing renewable energy, we aim to accelerate the realization of a decarbonized society by increasing the rate of self-generation and self-consumption.

Lead-acid battery system soldam

Product concept

A dam (battery storage system) is installed between the solar panels and the power conditioner, which blocks (charges) part of the solar power generation and releases (discharges) it at any time.

Product Features
