Aloha all,
With LG exiting the solar PV space I'm wondering
if their LG Chem affiliate is getting out of the residential battery
storage space (their RESU line) as well.
Anyone know anything about this?

Hi Jay I am not sure what non-cycling use is, I have mentioned before in my
experience where a cell in the string can become lower in charge and the
string loses capacity in discharge because the BMS shuts off the complete
battery when the troubled cell reaches low voltage cut out. To prevent
this,
Look at Blue planet, they have a BMS and l do not know what draw it has.
Can you lock out the battery with a contactor to reactivate the system

Aloha,
I’m in search of SolarEdge Optimizers.
If any of you have any leads on a source, please contact me off list.

Hi Jerry
This is for a generic GTBB with no battery sell back. So basically for as many
years as possible.

Well before l say anything, how long? I have locked out LFP for 180 plus
days and they held the charge, now if the BMS is connected the battery will
draw down. Now l can say that once a LFP that l use is full its fu and 99%
bypass the battery. Now also different brands tend to act somewhat

The main thing you can do when non-cycling is to set the charge voltage a
little lower than you normally would.
Check the manufacturer for the recommended full charge voltage (usually
3.6V/cell) that's 57.6V for a 48V pack. I set my absorb voltage to 57V even to
begin with. And float is closer

We have some government customers using LiFeBlue Battery as a UPS for radio
systems. Battery and radios are connected to a constant 14.2 Volt power supply.
The battery only discharges if the utility power goes off and recharges after
restoration. Operating for 3+ years.

anecdotal, but Blue Planet told me their LFP battery can sit uninstalled in
the box for several years with minimal self-discharge and no problems when
put into service.

Hi all the lithium experts.
Are there any issues with using LFP lithium in non cycling battery backup mode.
Or specific settings, brands etc that should be considered when designing for
GTBB, non cycling.
Thanks
