LG Chem Unveils New Full Home Backup Solution in Cooperation with SolarEdge -LG Chem's RESU10H Combined with SolarEdge's Energy Hub Inverter and Backup Interface Provides More Backup Options for Homes -This New Compatibility Offers Flexible Home Back Up with Optimized Energy Loads and Effortless Installation. SEOUL, South Korea, July 21, 2020 /PRNewswire/ -- LG Chem, South Korea's leading manufacturer of advanced lithium-ion batteries, has once again joined forces with SolarEdge Technologies, Inc. (SolarEdge), a global leader in smart energy, to bring compatibility with the LG RESU10H (400V, 9.8kWh) home battery. By incorporating SolarEdge's single phase Energy Hub Inverter and backup interface, homeowners can now choose how they power their home with a reliable and cost-effective solution. 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.

Energy Independence Goal We followed our partner Global Solar during the installation of a RESU10M, a residential energy storage system and exchanged a few words with the home owner. Warm Welcome Home owner Luca welcomed us on this early June morning with a gentle smile. The long-awaited day of energy independence has finally come by today. First Step Luca, an entrepreneur and the owner of a spray-painting company, is currently moving to his newly renovated home. The energy consumption of the new house was an important matter and the photovoltaic energy alone was not enough to cover the energy needs, which mainly occurred in the evening, when the family is using many home appliances after Luca and his wife come home from work. Luca knew that LG Chem's RESU10M battery is essential for the energy independence. Ready for Change Thanks to the Sunny Boy Storage 3.7 inverter, which is ready for independent inputs for three batteries, this storage system is ready to be expanded up to 30kWh in case the family buys an electric vehicle. Powerful but Removable Battery The RESU10M battery was a pleasant surprise for Luca because he expected a much bulkier device. The battery fits perfectly in almost any room: This was proven since the initial defined room of installation changed to the living room, because the battery is small, light and elegant. Due to its small size, the RESU10M can be installed anywhere and it does not prevent the residents from any limitations in their lives. Quick and Easy Installation The battery was a pleasant surprise also for Matteo from our installation partner Global Solar because it was enough to send only one person for the installation of this storage system instead of a team consisting of two or three persons. The savings for Matteo are obvious and even his electrician was happy because he had not to carry a heavy load. Reliability The RESU10M battery is covered by a 10-year warranty, just like all the other RESU battery series. This warranty is provided by LG Chem, a company that generates an annual turn-over of about USD 26 billion worldwide. This allows Global Solar and battery owners to enjoy a comfortable life at ease as they know that the warranty is supported by a financially sound company.
