Re: [RE-wrenches] LG RESU10 alternative
So our big issue right now is whether or not LG Chem honors their warranty on the recall or do they file bankruptcy and leave the installers holding the bag.

Re: [RE-wrenches] LG Chem batteries
In regards to LG Chem batteries, I'm surprised that there has not been more talk about this issue. Our patience is running thin. It appears that they are not going to send out RMA warranty replacement units anytime soon. We have had a number of resu10's go code 43. We rma'd them back to socal lg chem headquarters and now they are silent about when and where the replacements will appear. My personal idea is that there is a class action lawsuit against them and the payments to each installer cover the cost of replacement of the battery and inverter. We would of course not use their product but something that is proven to work. We need to make our customers whole again asap.

Drake, How long does it take to get Hasan on the phone, when you're onsite doing a service call? How many staff other than Hasan are trained to help installers with their battery inverters, who are onsite doing service calls? Do you happen to know if Hasan and crew have figured out a way for installers to change storage profiles without returning to the site?

Re: [RE-wrenches] Working with SBS 6.0 and LG Chem batteries
Hey Dave, Thanks for your input. The issue at stake here is that one or more large solar supply companies misrepresented the facts on this combination of inverter gear and battery. They did start the year out with LG Chem being the first battery on the compatibility list. After months of complaints they quickly pivoted somewhere around June. I know there are other installers out there, we hope to hear from them too.

Re: [RE-wrenches] Working with SBS 6.0 and LG Chem batteries
Actually LG Chem was first on that list earlier this year. After recent developments they started changing their views in June, and now it seems like BYD is their first choice. We are most interested in talking to installers who have used the LG Chem/SBS 6.0 with some success.

[RE-wrenches] Working with SBS 6.0 and LG Chem batteries
Hello Wrenches, We would like to hear from anyone who has had recent experiences dealing with installation and operation of SMA-America SBS 6.0 battery inverters, ABU's etc. along with LG Chem batteries. We would like to discuss the functionality of this combination of inverter/battery in comparison to other inverter battery options out there. Thanks, Vic Guillot Sol Sierra, Inc.

Re: [RE-wrenches] SMA Sunny Storage AC-coupled with SB6.0 won't recharge LG Resu batteries during backup ops
Hi Wrenches, Thanks for your comments Jerry, Our company too has had issues with the problems you discuss. It basically seems that someone has misrepresented what is "doable" with the SMA storage inverter, ABU and Sunny Boy PV inverters. We made the mistake of installing 3 in a row and then finding out these issues with SMA. We really hate having customers mad at us! We thus avoid these situations like the plague, or these days the Covid! So what we have come to understand here is that you cannot AC couple SMA and the LG Chem battery. So what is the point of having the ABU? Thanks to Scott for bringing these issues to light. Vic Guillot Sol Sierra, Inc.
