Re: [RE-wrenches] SMA Sunny Storage AC-coupled with SB6.0 won't recharge LG Resu batteries during backup ops
Scott, Wrenches We have had systems with the SMA storage but we have used the BYD and have had no problems so far with recharge and operations all as expected, it may be an issue with LG programming and the SMA not communicating properly JUerry On Fri, Jul 10, 2020 at 2:57 PM wrote: > We have a design with Sunny Storage 6.0 inverter, SB 6.0 PV inverter, the > SMA Automatic Backup Unit, and three LG Resu batteries.

[RE-wrenches] Admin post, please read: Wrench List archives
Hi there Wrenches. If you have any questions about this, please contact me off-list. A member has discovered that there are message gaps in the third-party message archive we've been using. It shouldn't be happening, but it is. So, I've changed the archive link in the message footers back to an older one we used to use, and it should be fairly complete, at least for recent years. While I've got you here, it would be helpful for both readability and bandwidth if Wrenches would edit out old parts of the messages in their replies. For example, sometimes there might be 5 or more copies of the Wrench List footer in replies to replies. Also, copies of embedded photos in replies are usually not needed, they just create more clutter on Wrench members' hard drives. Finally, if there is a message you cannot find in the archives, please let me know and I will try to find it for you. I keep ALL old Wrench list messages on my computer, going back to Oct. 1999 when I started this list. Thanks, and keep on Wrenchin'. You all are making a difference in this world. ___ List sponsored by Redwood Alliance List Address: RE-wrenches@lists.re-wrenches.org Change listserver email address & settings: http://lists.re-wrenches.org/options.cgi/re-wrenches-re-wrenches.org List-Archive: http://lists.re-wrenches.org/pipermail/re-wrenches-re-wrenches.org List rules & etiquette: www.re-wrenches.org/etiquette.htm Check out or update participant bios: www.members.re-wrenches.org

Re: [RE-wrenches] SMA Sunny Storage AC-coupled with SB6.0 won't recharge LG Resu batteries during backup ops
Hi Howard, I am sure that the SMA guy here on wrenches will give you a better answer. If not I would escalate this at SMA as you are right. The LG will do what you want. Something is not programmed correctly. Three of the Resu 10H are going to take some time to replace near 30KWH.

[RE-wrenches] SMA Sunny Storage AC-coupled with SB6.0 won't recharge LG Resu batteries during backup ops
We have a design with Sunny Storage 6.0 inverter, SB 6.0 PV inverter, the SMA Automatic Backup Unit, and three LG Resu batteries. Works like a charm during normal grid ops but when it goes into backup ops, the Sunny Storage increases frequency to between 60.6 with blips up to 61 hertz, resulting in the PV inverter throttling back from 5,000+ watts to between 1,300 to 345 watts. The result is that the batteries do not recharge from the PV during backup mode, even when SoC is less than half capacity. This also means the max power through the ABU to the "whole house backup" is the 6,000 watts from the Sunny Storage plus the (very) retarded power output of the SB PV inverter.
