Frequently Asked Questions Regarding LG Energy Solution's Battery Recall and Replacement Program

Frequently Asked Questions Regarding LG Energy Solution's Battery Recall and Replacement Program Q1: Why is LG Energy Solution replacing my battery? A: In cooperation with the global product safety authorities responsible for product recalls, LG Energy Solution (LG ES) recently announced a voluntary recall and free replacement program for certain residential energy storage system batteries. The recalled home batteries can overheat, posing a risk of fire and emission of harmful smoke. LG ES is undertaking this voluntary action as part of its commitment to product safety and to providing the highest quality and service to its customers. Q2: Should customers turn off the batteries? What should customers do until the batteries are replaced? A: No action is required by customers whose batteries are connected online, because LG ES has remotely deployed modifications to impacted batteries to reduce the risk of overheating. Customers whose batteries are offline should call LG ES or their distributor/installer for further instructions. Out of an abundance of caution, if a customer plans to leave home for an extended period of time, such as a vacation, LG ES recommends turning off the system to avoid leaving the home battery in a fully charged condition. Q3: Will LG ES replace affected units with new batteries? A: Yes, LG ES will replace the affected batteries with newly manufactured batteries that incorporate state-of-the-art safety features that were designed to prevent overheating that might lead to fires and/or emission of harmful smoke. Q4: Please explain the replacement process. A: The program will begin in October 2021. LG ES will contact the original installers for the batteries to arrange for that installer to perform the replacement service work. If for any reason the original installer is not able to perform the work, LG ES will make alternative arrangements. LG ES has already started contacting the owners of the batteries with instructions, but battery owners, installers and distributors who would like additional information should call LG ES' recall help line listed at the end of the FAQ. LG ES will work to arrange a replacement schedule that is convenient for you. However, please understand that despite the company's best efforts, there may be some delays, due to factors that are outside our control, such as the severe global shortage of semiconductors and other components of residential energy storage systems. As stated above, if you own an "offline" battery, please contact LG ES as soon as possible to provide the company with your specific location and battery information to start the process as soon as possible. Q5: Will LG ES extend the existing Warranty period for the product as part of its replacement program? A: Yes, all replaced remotely modified batteries will come with a new ten (10) year warranty period, starting from the date of installation. Call your distributor/installer for further details. 1.

CONTACT DETAILS: For further information, please contact LG Energy Solution Australia's product department by phone on 1300 677 273 or email at productau@lgensol.com. You can check your battery's serial number by following the below guidelines and confirm its eligibility for replacement via the link below. How to check whether your battery is eligible for a free replacement: Step1: Check the Serial Number of your product. The following illustration shows how the unique serial number appears on a sample ESS RESU Home Battery. Serial numbers begin with "R" and are 22 or 23 characters (a mix of letters and numbers). In the example below, the unique serial number is "R15563P3SSEG11610317001". For RESU 7H and RESU10H (Type C, Type R and Type R (Secondary)) There are two methods to check the serial number which appears in two places. Underneath the battery, adjacent to the cable entry. By using a smartphone, you can photograph this label. You could try selfie mode. Please note that with this method, it may not be possible to capture the QR code, meaning you need to transcribe the serial number manually. Behind the access cover at the bottom right of the battery. To access: (i) Open the two latches by pressing the child-proof tab with your thumb before unlatching. (ii) Remove the access cover by opening slightly (2-10 degrees) and lifting off. Be sure to lift the door off - it is not hinged. (iii) You can then see the serial number label on a clear plastic cover. You can either photograph and transcribe it manually or, if your smart-phone has QR capture, direct it at the QR code to capture as text. (iv) Reattach the cover by holding in place and re-latching. For RESU3.3, RESU6.5, RESU13 and RESU10 It is not always possible for customers to directly determine the serial number, due to its location underneath battery cables, but you may attempt before turning to alternatives. To determine the serial number directly: i. Look to the Right-Hand side of the battery. ii. You may see the serial number label partially obscured by battery cables and/or conduit. You can either photograph and transcribe it manually or, if your smart-phone has QR capture, direct it at the QR code to capture as text. Do NOT attempt to dismantle the battery or cabling for easier access to the serial number. Instead, use an alternative option. Alternative options are: Check your installer-provided documentation to see if your installer included your battery serial number. Contacting your installer to check if they recorded your battery serial number in their internal records. Arranging a site visit for your installer or a qualified electrician to check your serial number. Please ask them to first contact LG Energy Solution Australia's product department at productau@lgensol.com or on 1300 677 273 prior to their visit so we can provide technical guidance and arrange payment for their time. Contacting LG Energy Solution Australia's product department to arrange an inspection and (if applicable) a replacement free of charge. Step2: Enter your RESU serial number in the page linked below to find out whether your LG Chem or LG-branded RESU product is eligible for replacement.

Energy Independence Goal

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.
