Battery details

LG Chem’s North American residential battery range offers AC- and DC-coupled solutions with capacities up to 9.8 kilowatt hours (kWh). Two voltage options are available, pre-matched with compatible inverters and suitable for both indoor and outdoor installation:

  • Low-voltage 48V: with capacities of 3.3, 6.5 and 9.8kWh; and,
  • High-voltage 400V: with capacities of 7.0 and 9.8kWh.

The 400V RESU10H (9.8kWh) product is compatible with SolarEdge’s StorEdge, which is a DC-coupled storage solution based on a single inverter for both PV and storage. Additional inverter compatibility options will become available later in 2017 to provide homeowners with a range of pre-tested solutions from the industry’s leading suppliers.

LG Chem’s residential batteries will be available via a number of leading solar/storage providers in North America. Following last year’s announcement of a partnership with LG Chem, Sunrun – one of the leading U.S.-based residential energy system providers – will be supplying LG Chem’s RESU systems. Sunrun already has installed initial systems in both Hawaii and California.

Sunrun adds LG Chem batteries to its U.S. solar-plus-storage system

Sunrun logoSunrun Inc. and LG Chem, are launching a partnership for the U.S. residential solar market, in which Sunrun will offer LG Chem’s lithium-ion RESU batteries through Sunrun BrightBox solar-plus-storage systems.

LG Chem’s lithium-ion batteries have a track record of performance success in the electric vehicle market and offer durability at an affordable price point. LG Chem is the world’s largest automotive battery supplier, counting 16 of the top 29 global automakers as partners.

“The energy storage market is advancing at a breakneck pace. At Sunrun, we are enabling a home energy management service that integrates rooftop solar generation with onsite energy storage to offer greater energy choice and savings to our customers while helping to modernize the grid,” said Chief Marketing Officer Michael Grasso. “We’re thrilled to offer LG Chem’s best-in-class battery technology to homeowners. The partnership with LG Chem supports our financing advantage, enabling our customers to install solar plus energy storage for little to no money down.”

What is the Sunrun BrightBox?

Sunrun BrightBox combines solar generation with energy storage giving consumers new ways to manage their energy. In Hawaii, Sunrun BrightBox is giving consumers the ability to self-supply their own energy day and night. In the future, Sunrun BrightBox will allow consumers with time-of-use tariffs to time shift when they use solar energy to minimize paying peak rate energy prices.

BrightBox will also allow customers the ability to have access to power when grid power isn’t available. Sunrun and their installation partners take care of everything from permitting to installation so customers can go solar hassle-free. BrightBox is currently available in Hawaii to customers as an affordable monthly or prepaid lease for little to no money down or as a direct cash or loan purchase. All customers need to think about is how much money they’ll be saving. More states will be announced in the coming months.

Sunrun will also make LG Chem’s battery solution available to the entire solar energy industry through its subsidiary AEE Solar, the leading nationwide distributor of solar products.

SolarEdge’s StorEdge now compatible with LG Chem’s new high voltage batteries

solaredge lg chem

With both on-grid and backup solutions, the new offering supports increasing self-consumption, providing power backup, and enabling energy independence. This is the self-consumption version.

SolarEdge Technologies, a global leader in PV inverters, power optimizers, and module-level monitoring services, and LG Chem Ltd, announced the compatibility of SolarEdge’s StorEdge solutions and LG Chem’s new high voltage RESU10H and RESU7H batteries. The product compatibility will help further advance the accessibility to cost-effective residential solar generation, storage, and consumption.

Here is our Q&A with SolarEdge on its StorEdge technology if you missed it.

With both on-grid and backup solutions, the new offering supports increasing self-consumption, providing power backup and enabling energy independence. LG Chem’s RESU batteries use Li-ion technology, and their compactness allows for easy and flexible installation, both inside and outside. The RESU batteries have a high energy density and are designed for high efficiencies and a long lifetime.

“Through this collaboration, SolarEdge is adding LG Chem RESU batteries to our StorEdge solution compatibility in order to extend our offering of cost-effective and integrated energy generation, storage, and consumption,” stated Lior Handelsman, Marketing and Product Strategy VP of SolarEdge. “Building on our respective expertise, we hope to lower the cost of solar energy and accelerate the adoption rate of integrated solar energy generation and storage.”

“Offering battery compatibility with SolarEdge’s StorEdge solution is ideal as the company is a leading global inverter manufacturer,” said Sung Hoon Jang, Ph.D, Senior Vice President of LG Chem and Head of ESS Battery Division. “Taking RESU’s compatibility with various inverters as a key factor, LG Chem is very pleased to announce StorEdge as one of our main compatible inverters.”

Designed to manage both functions with just one SolarEdge DC optimized inverter, the combined solution will include remote monitoring and troubleshooting to keep operations and maintenance costs low. The StorEdge™ solution will support both DC and AC coupling. As with SolarEdge PV systems, StorEdge™ offers enhanced safety by reducing voltage to a safe level upon AC shut down when not in backup mode. The upgrading of existing SolarEdge systems is supported.

Huge solar + storage system (7 MW) powered by LG Chem

LG Chem solar storage

S&C Electric Co. is making one of the largest solar and energy storage systems in the United States, and to do so, commissioned a 7-MW/3 MWh battery energy system from LG Chem. Commercial operation of the system will be run by its owner Half Moon Ventures (HMV), a renewable energy company, and will be used primarily by the local municipal utility of the Village of Minster, Ohio.

The battery energy storage system (BESS) and 4.2-MW PV systems are installed in the service territory of the Village of Minster. The BESS provides four distinct revenue streams for HMV and the Village: Frequency regulation; Transmission & Distribution cost deferral; Power quality improvements; and Peak demand shaving. The project is an example of how energy storage provides multiple value streams for numerous stakeholders, while providing end users with improved services and reliability, especially for the 61 million customers served by the PJM Interconnection, a regional transmission organization (RTO) that manages the movement of wholesale electricity in all or parts of Delaware, Illinois, Indiana, Kentucky, Maryland, Michigan, New Jersey, North Carolina, Ohio, Pennsylvania, Tennessee, Virginia, West Virginia and the District of Columbia.

LG Chem delivered an integrated battery solution, battery installation supervision, and commissioning to S&C, which integrated the overall system with the electric grid and provided the power conversion system.

“This project is a key example of how energy storage can generate tangible revenue streams while providing critical grid services,” said Mike Edmonds, president, U.S. Business Unit at S&C. “S&C has been able to deliver a comprehensive energy storage solution through its collaboration with LG Chem and is very proud to be moving the energy storage industry forward.”

“LG Chem is continuing to provide world-class solutions for key customers and projects worldwide,” said Sunghoon Jang, senior vice president, Energy Solution, LG Chem. “Collaboration on this project with S&C has provided not only key learnings, but also a system that provides the community with critical grid services, as well as commercially viable revenue streams for the system owner and local utility. This project shows how the energy storage industry has entered another phase with viable projects for customers and end users.”
