The LG charger probably generates the Heartbeat signal you need to fool
the contactor to be on for charging.
I Think! My experience is with the 48V RESU 10 and not the RESU 10H
that is a 400vdc battery.
There were a few people on here with 10H so hang on.

I have an LG RESU-10H Gen2 Type R battery that has discharged so far
that the display will no longer turn on. Apparently, there is a
recovery process for this situation that involves using an
LG-sanctioned charger that will properly manage the BMS throughout the
recovery process. I have access to the correct charger for this
purpose.
However, I have searched the Internet and Youtube and cannot find any
instructions that explain how to operate the charger and recover the LG
battery.
Does anyone on this group have experience with this situation and can
help? Is there a service manual for the LG RESU battery that explains
how to recharge it in this situation (again, can find nothing but the
installation manual on the internet).
Many thanks for any insights.

Someone asked about the loss on the discover AES rackmount.
"The contactor is bi-stable so it doesn't require extra holding current
in either state. The ON state loss is 7.49mA."

Also below is a response from Schneider on closing the loop with EG4.
Thanks for the feedback Dave.
I visited Signature last year to offer training. The EG4 is available
in the dropdown menu for BMS Setup in v1.18 InsightLocal firmware.
Integration with XW Pro has worked well from what I have seen.

Howie, I think you should also look again at the Discover rack mount
system in the link below. Nice 75 year old company that made it's name
on Locomotive batteries. Their prices are way down around 14 K for
30Kwh with heaters. If you have not looked at Lynk2 their gateway
closed loop into SMA, Schneider, Solark, Morningstar and a few others
you should.
The only problems I have with Schneider are pretty easy and get
resolved because I only use them and take all of the training. Conext
Insight is a home run for my clients. Schneider also hired me to test
their first closed loop system with LG back in 2017 and it still is
working fine.

We gave EG4 and Signature another chance after promises from their
dealer oriented support department that we could expect better service
from them. We had an EG4 BMS crap out a couple months ago after only a
few months. Lots and lots of communications with Signature and we still
don't have a BMS or replacement battery. It's been a shit show with
them. I think we are going to remove them and install 3rd party BMS's
and find some use for them. Maybe donate them. We've only had luck with
Schneider/Discover pairings in closed loop. A large system we did with
Sol-Arks never really worked in Closed loop, despite Discover coming to
the site. Most likely it's a Sol-Ark issue, but we've reached Sol-Arks
technical expertise limits. Even with Schneider/AES, there have been
some issues that are causing me to re-consider Li for offgrid. I just
had a conversation this morning with a long time off-grid pro and he
said the same thing. It used to be, we'd install a wet lead acid bank
and then ten years would pass before hearing from the client when it
was time for another bank. Sometimes fifteen years. Our call backs with
systems over the last ten years, first with a decline in equipment
quality and then the switch to Li are costing us too much money and
causing a lot of heartburn for our clients. Rant Over

Hi All,
I've searched the archives for info pertaining to EG4 inverters and
batteries. The comments have been mostly positive. I have stayed away
from EG4 until now in part, for the reason the Michael Morningstar
suggested last June - that is, they seemed very oriented to the DIY
market and not real serious contenders in the lasting marketplace.
However, I was at RE+ Boston this week and was quite surprised to see
that the EG4 18k inverter is, for all I could tell, identical to the
Fortress Envy 12k, in both physical layout as well as menu structure. I
have very limited experience with the Envy (having just installed my
1st one last week, in order to compare it to the Sol-Ark 15). I don't
have any thoughts about it yet, except that the font on the screen is
quite small and the opening screen is not as intuitive as the Sol-Ark,
but that might just take familiarizing myself more to the Envy (and/or
the EG4).
My question is, for folks who have had either the Envy or the EG4
inverters installed for a decent period of time, what is your current
take on their functionality, durability, and for the EG4, the quality
of support? Also, what experience have folks had similarly with the EG4
LLI batteries? I'm not unhappy with the Sol-Ark or in general the
Fortress eVault Max battery, but there are some attractive things about
the Envy and potentially the EG4 18k, and the price point and seemingly
smart configuration of the EG4 LLI batteries are certainly
eye-catching.
I'm also currently starting to lean toward using Lithium batteries and
inverters from the same manufacturer, as I'm growing weary of the
mismatching firmware updates that are causing somewhat frequent issues
between the 2 components. Although the inverter/battery integrated
units (i.e. Sonen, Tesla, etc.) don't seem ideal, since the market is
so volatile at the moment. If one component fails, I'd like the option
to replace it with a different brand without having to replace the
other component as well. Using the same manu doesn't necessarily cut
down the problems, but it certainly will help in the troubleshooting
process by hopefully having less of the "not my problem" or "we haven't
seen that problem" responses from tech support.
I really don't like making forays into bleeding-edge technologies, so
I'm hoping to gain some experienced insight.
Thanks,
Howie Michaelson
