At Intersolar, Tabuchi America, announced the launch of its Next Generation Eco-Intelligent Battery System (EIBS). The all-in-one system is compliant with the cUL 9540 certification requirements, which provides 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 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 Harumi McClure, COO and President of Tabuchi America. “We’re pleased to receive the cUL 9540 certification compliance on our highly-efficient Next Generation EIBS. 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.”
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 standard certifies Tabuchi’s Next Generation EIBS as a home energy storage system that interacts safely with the cUL 1741 requirements certified hybrid inverter.
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. This leads to higher system efficiency through one fewer DC-AC inversion.
The modular stackable battery system is key for customers with larger homes, as well as those who are looking to utilize the system for backup power. The increased storage capacity can help customers keep the critical electrical loads operational longer during a blackout. It also lowers their energy bills by reducing the amount of electricity purchased from the grid during peak hours when prices are highest and/or when utilities levy additional charges. Added surge capability enables the EIBS system to power motor-driven loads such as water pumps, which have a higher starting load, allowing greater integration within the home.
