Re: [RE-wrenches] LG Chem RESU warranty

[Daryl DeJoy via RE-wrenches]

It literally took a year and constant pestering to get a shipping carton 
and finally replacement batteries. I had to monthly send "bordering on 
the insulting" email inquiries to them. Both batteries are finally back 
and performing well.

Re: [RE-wrenches] LG Chem RESU warranty

[Scot Arey via RE-wrenches]

I agree. I also had a Bolt battery recall and we joked that GM probably got 
better priority than Solar CenTex for limited battery stock.

Glad you added that important context.

Just as a bit of context, LG is in the middle of a gigantic warranty recall and 
replacement of every 2019-2022 Chevy Bolt battery pack. 

As far as I can tell the recall is overly cautious, but it’s good that they are 
stepping up. 

It’s not an excuse for bad service, but an explanation for why there might be a 
shortage of both batteries and attention.

Re: [RE-wrenches] LG Chem RESU warranty

[Dave Angelini Offgrid Solar via RE-wrenches]

Check the charge rates !  It is from LG and I know they are different 
voltages. My experience is old and not on the new gear.


They are from LG who after working directly with them..

Either way, there are too many good choices out there to be installing 
NMC batteries in or near a home these days.

I think we are discussing different batteries.

The LG Prime 16 is a high voltage 400-volt battery compatible with 
SolarEdge that operates at that same nominal voltage.


I have heard of a 48-volt LG but it is not out in large quantities, if 
at all,  and is not the one I am referring to.


The LG Prime 16 undoubtedly has higher charge/discharge rates than the 
LG Resu 10.

I wish I shared your optimism Scott on the  LG Prime 16 being better 
battery than the LG Resu10. When I field tested the Resu 10 with

Schneider in 2017,
the specs on the unleased 48VResu 16 were the same for charge and 
discharge as the Resu10. You would think the larger battery would be 
better

but it was not. The same BMS I would guess.

The fact that you can't use any of these LG batteries without the loop 
closed to the inverter is a serious flaw (they shut down without the 
heartbeat)
 that people like Discover AES learned from. Something very wrong that 
LG is still in the dark ages of a home battery, in my opinion.


AES did not carry out this poor design policy and built the perfect LFP 
for my clients and my wife and I.

 LG is NMC and even advertised them installed in a Kitchen?

We killed the Resu 10 with too much XW charge current BTW. The dead ones 
went out to the desert of California to be recycled. Another story.

LG seems to have improved its position and has replaced in a more timely

I'm hoping the LG Prime 16 is a better battery than the LG Resu10. Seems 
so and I like the high discharge capability that really pairs well with 
a SE11400 Energy Hub inverter. We've had one warranty of a Prime 16.


Feel free to contact me offline to makew sure you have the right numbers

was to make improvements.

Have any of you waiting for repair / replacement of these battery packs 
had any success in the last year?


I have -3- deemed defective units. One was sent back, over a year ago, 
still no word from LG on replacement status.


The other -2- have been awaiting return boxes for over 6 - 9 months.
