Product Spotlight - LG Chem RESU Home Battery Energy Storage


LG is a leader in the home electronics industry and manufactures some of the most popular solar panels. Outside of making solar panels, LG's battery subsidiary, LG Chem, produces one of the most popular batteries in the U.S. market: the LG Chem RESU 10H battery.

LG chem is ranked as one of the world's largest lithium-ion battery manufacturers with 29,000 employees and manufacturing facilities in South Korea, China and the US. The company supplies a diverse range of energy storage products for many industries including electric vehicles, portable electronics (mobile phones) and stationary applications. The large range of stationary lithium battery systems has positioned the company as one of the industry leaders in home solar battery systems and larger commercial energy storage (ESS) installations.

LG Chem RESU Battery Home Energy Storage

The RESU or 'Residential Energy Storage Unit' range consists of a 400 volt lithium battery available in 9.8kWh size.  As with many other home battery products, the LG Chem RESU is sized for day-to-day use at your home and is often paired with a home solar panel system.

When your solar panels produce more electricity than you can use in your home, you can store the excess electricity in the battery system instead of sending it back into the grid. Later, when your panels aren’t producing enough electricity to meet your home’s needs, you can use the electricity stored in your battery instead of having to buy it from your utility company.

Full Home Backup Now Available Using LG Chem!

Available in North America from July, LG Chem's new full home backup solution will deliver backup power with a highly efficient DC-coupled design that supplies power during grid interruptions or power outages. This new offering features flexible home energy loads, which allows users to manage their energy throughout the home or opt for even higher efficiency and choose pre-selected loads for backing up.

The Energy Hub Inverter and RESU pairing with a generator can reach up to 28kW of power and 60kWh of storage. This cutting-edge solution is scalable while maintaining efficiency, to support any size household. For families that may grow or increase their energy use in the future, like with an electric vehicle, additional RESU10H batteries can even be added at a later time. What's more, when connected to six batteries and an EV charger, the new solution can provide more than enough power to the user's vehicle directly from the solution's advanced solar system.

SolarEdge's Energy Hub Inverter rating requires fewer components in the system design which increases the aesthetics but reduces the complexity of the installation. The Energy Hub Inverter also provides homeowners the ability to monitor both solar production and energy storage through an all-encompassing app, called mySolarEdge. The new Energy Hub Inverter and RESU solution offers a cost-effective and easy-to-use residential storage solution that will enable more families access to reliable, renewable energy.

LG Chem RESU Design

Boasting a sleek and compact design, this 9.8kWh LG RESU10H battery uses LG Chem's advanced lithium-ion battery technology to boost efficiency while maintaining high energy density. The compact design of the RESU10H allows simple and flexible installation both inside and outside the home. When coupled with SolarEdge's easy-to-install Energy Hub Inverter homeowners can optimize their battery energy with a 90.8% combined system efficiency and 200% DC oversizing.

All LG Chem RESU batteries are IP55 weather-rated. This means they can be installed in a semi-outdoor location such as a verandah or carport, but should not be located in a position exposed to direct sunlight, especially during the warmer months. As with any electrical/battery system, excessive prolonged heat is detrimental to the performance and life of the system.

LG Chem RESU Functionality

The functionality of one solar battery next to another can vary; some batteries have excellent off-grid capabilities, while others offer software solutions for rate arbitrage.

LG Chem has made a concerted effort to ensure their battery solution is compatible with most common brands and types of off-grid and hybrid inverters. This means that, as long as your installer installs the correct components, your LG Chem battery will be able to provide backup power for your home when the grid goes down.

Home Battery Storage Incentives

In some cases, depending on where you live, you may have access to financial incentives that can reduce your home energy storage installation costs. For instance, if you live in California, you could get a cash rebate that covers most of your home battery costs through the Self-Generation Incentive Program (SGIP). Other states (such as Massachusetts) are in the early stages of evaluating battery storage performance incentives as well, and several states already provide cash rebates.

Home Batteries Provide Energy Independence

Batteries paired with a solar system are essential for energy independence! Protect your home from the next power outage and keep your lights on, phones charged, and no puddles under the fridge. You can rest assured that even when your neighbors lose power, your home will still be humming!
