LG was one of the first players in 2016 for resdential storage. They are a huge manufacturer of NMC type lithium batteries. We all know now that is type of battery NMC is not as safe as type LFP, all other things being equal. The cell type we used is still the upgrade option in the Tesla Roadster BTW.
I thought it was unreasonable that they did not want to find the root cause of the failure here with Schneider XW. It is their company and I got over it. Schneider was great and they also learned alot. Discover AES was in the loop with the failure here and learned also. Many of the folks at AES are from Schneider. AES engineered out all of the bad design choices that LG made and hit a homerun. The failure symtom was a blown 200A fuse with little load at 85% Soc. Replacing the fuse, the battery came on and showed 98% Sol or battery health. A new fuse was installed and the battery BMS powered up and blew the 200A fuse in a couple seconds. We tried a few DC 48V rated small loads to rule out the inrush of an XW. We tried a different XW and also tried a CSW. Lot's of blown fuses...My guess was a cell breaking down under load. Still trying to recycle this bad battery responsibly. I know what is done currently in my area and it is not pretty. Anyone with advice? LG was of no help here also. The other LG RESU 10 here is fine but we limit it to a CSW and 1/2 of the rated charge current. It is on my list to send a check to the Wrench boss here this week! Cheers !

Speaking was a rep from LG Chem and from SolarEdge. I asked the LG rep if there had been any production problems with the LG production line. He said with a straight face there were no problems and we should order now before they ran out. I pulled up a trade article on my phone about a shut down in the production line at LG Chem and we passed it around in the back of the room and sniggered. I am not saying all LG Chem reps are liars but this one sure was. I hope this behavior is not encouraged by LG Chem. Hearing a poor report on the recall is further evidence that LG Chem may not be a good company to buy product from. What is the overall sataisfaction level amongst this forum members with LG CHem?

The recall has been disorganized. We had about 7 batteries under recall. LGC had some 3rd party outfit that was going to go to customer homes and do the swap-out and we said, "oh, no...we'll replace the batteries for our customers thank you." I still have three batteries with unconfirmed replacement. The shortage of old style Resu10 batteries means they must, in their own words, buy these batteries off the open market place to provide back to us and end consumers under recall. Crazy. Now I am a big fan of the LG Prime 16 so far. Nice looking package and just the right amount of storage. But the LG oversight of the recall could have been done better especially comms with installers that didn't have recalls so they could allay fears of homeowners that might have read a headline and wondered if their battery was a safety hazard.

How has LGC been as far as responsive and easy to work with on this recall? marco On Monday, May 10, 2021, Dave Angelini Offgrid Solar wrote: Wrenches, I testted the RESU 10 48V here for Schneider back in 2017. LG never really wanted to know the root cause of the failure and cancelled the use of XW with their battery. One of my Austrailian friends sent me this about the recall. In December last year, LG Energy Solution triggered a voluntary recall in the USA [11] after receiving five reports of fires resulting in minor property damage. These incidents were associated with LG Chem RESU 10H residential energy storage systems with specific serial numbers sold from January 2017 through March 2019. The recall involved around 1,800 battery systems. On Friday, a recall notice was posted on the Product Safety Australia web site for the following models with cells manufactured between March 2017 and September 2018 from certain production lots. * RESU7H_Type R * RESU10 * RESU10H Type-C * RESU10H_Type R * EM048063P3S4 * EM048126P3S7 DAVE ANGELINI OFFGRID SOLAR "WE GO WHERE POWERLINES DON'T" E-MAIL TEXT 209 813 0060 Links: ------ [1] http://members.sti.net/offgridsolar/ [2] mailto:[email protected] [3] http://www.millersolar.com/ [4] mailto:[email protected] [5] mailto:[email protected] [6] mailto:[email protected] [7] mailto:[email protected] [8] mailto:[email protected] [9] mailto:[email protected] [10] mailto:[email protected] [11] https://www.cpsc.gov/Recalls/2020/lg-energy-solution-michigan-recalls-home-energy-storage-batteries-due-to-fire-hazard
