[RE-wrenches] LG Battery charger instruction

[david quattro via RE-wrenches]

Hi Tom,
  a few years ago I decided to buy my own LG battery charger because we
needed the damn thing so often. Now I only use it once or twice per year,
because I stopped installing LG batteries. Here is the instruction I have
which works on my charger (same charger as the LG-sanctioned :: the
manufacturer is VOLTEQ and the model # is HY20010EX)

On the battery itself, you need to pop the black (aesthetic-only) cover off
the top of the battery.  Under there are several 10mm fasteners that hold
down the actual watertight cover. Inside there are some fuses - if any of
these fuses are blown, LG told me that the battery is toast and LG needs to
take it back and rebuild it. But if your fuses are good then you can
determine the positive and negative leads by red and black conductors.

* The RESU10H battery should be charged at 152 Volts.

*Instructions for Using Volteq DC Power Supply to Charge Batteries*

   1. Make sure the "O.V. Set" knob (second knob from the left) is set to
   the maximum setting before you begin.
   2. Turn the AC power on using the air switch in the back.
   3. Enable the output by pushing the green button to 'IN' position.
   4. Turn the current knob (the leftmost knob) to slightly above minimum
   so that the CV light is on.
   5. Use the two knobs on the right to set the voltage to desired level
   recommended by the battery manufacturer.
   6. Connect the battery to the back terminals, make sure the polarity is
   correct: + to + and - to -.
   7. Turn the current knob to maximum, or the desired current recommended
   by battery manufacturer.
   8. Watch the charging progress, when the current is below 1A or 1/10 of
   the maximum charging current, it is probably time to stop. Make sure the AC
   power never goes offline during the charging process.
   9. Stop the output using the green button, disconnect the battery from
   the power supply, and then turn off the power supply.

You should start a new thread and not use this one. You will get more 
response! Good Luck!

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.

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.

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 conf
