SMA storage only works with BYD, for what ever the reason (software) LG

Wanted to share my experience with the SMA SunnyBoyStorage (SBS) with the LG
and BYD battery combo.
For background, not until installation nearly a year back did we discover
that despite early marketing literature claims, the LG batteries would not
recharge during backup operations. This was be
Hi Scott,
Agree with all you have said and would add that my
experience with the failed 48vdc LG RESU 10 proved to me that LG needed to
go back and redesign the whole line of residential storage. Not ready for
prime time. It probably is just a good choice to stay away from their NMC
batteries.
@ Jerry Shafer:
I think the title of the post clearly lays out that the issue I was
experiencing is with LG Resu batteries. I am glad that you are having good
outcomes with BYD but I never said this was part of my problem.So when
you say you are "doing it pretty often" I'm assuming you are
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

We do it pretty often and have never had an issue, right out of the gate we
were told that BYD is the only battery option available, l understand your
frustration but how did you determine that LG was an approved solution in

An update.
LG ESS is simply not compatible with the SMA represented system of SMA
storage inverter, Automatic Backup Unit, and its SMA PV inverter.
Just cannot AC Couple and use solar to recharge the batteries because as
soon as the battery changes from charging to discharging, it bleeds of

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.

We have a design with Sunny Storage 6.0 inverter, SB 6.0 PV inverter, the

during normal grid ops but when it goes into backup ops, the Sunny Storage

Aloha amigas y amigos.
Have any of you installed any of the new Sunny Storage inverters with the
accompanying backup switch?
Any feedback?
