Tabuchi America offers new solar-plus-storage gear

July 11, 2017

Tabuchi America, calling itself the world's leading residential hybrid solar-plus-storage manufacturer, announced yesterday the launch of its "next generation" Eco-Intelligent battery system (EIBS). The all-in-one system is compliant with Underwriters Laboratories' cUL 9540 certification requirements (the "c" reportedly means "Canadian"), which provide third-party validation of safety, reliability and efficient energy management for hybrid solar-plus-storage systems.

Tabuchi's grid-friendly system includes a high efficiency inverter, stackable batteries and integration with GELI software for what the firm called the most adaptable battery storage system on the market.

"As interest in energy storage grows in the residential sector, attention to safety regulations is more important than ever, not just to protect the safety of people and property, but also to expedite the permitting process," said Tabuchi America President Harumi McClure in prepared remarks. "The system is designed for adaptability and ease of installation with a direct current (DC) coupled battery.

"This maximizes the amount of solar energy utilized by the system and safely provides solar power to the grid and to residential customers during power outages," she added.

While there are many efforts to develop and apply safety standards for the rapidly evolving energy storage industry, the cUL 9540 certification compliance is limited to a relatively small number of energy storage manufacturers, the firm said. The standard certifies the system as a home energy storage system that interacts safely with the cUL 1741 requirements certified hybrid inverter, it added.

Consumers get more out their system because both the battery's bi-directional converter and the solar inverter are DC-coupled. This allows the energy generated by the solar panels to directly charge the batteries without first converting to alternating current (AC) like most storage systems, the firm said, adding this leads to higher system efficiency through one fewer DC-AC inversion.
