Larry and Alex explained one of my problems was low capacty early shut

We did the LG RESU 48v field testing here for Schneider. Never had any
problems with this and both of their cc's. Still running fine 2 years
later.
What I found was in the effort to get to 100% Soc there would be
micro cycles of the battery. By staying below 100% there was not any more

Hi All,
As Larry said, when a lithium BMS disconnects, this causes a "load
dump" just like disconnecting a lead-acid battery. Well-designed
chargers (solar or otherwise) should be able to handle this without
damage, though a failing or poorly-designed lithium battery may cause
this to happen many
Hello Larry is always a good source. I have used Morningstar MPPT 60 s on
my few LiFe po4 systems 4 years now, no controller problems or equipment
problems yet. I imagine when the BMS disconnects battery voltage high,
controller output goes high for a short period i will put an Egauge on the
outpu
There was some off board chatter about this subject but I think it is useful to
some to copy my comments on the board.
If a Li battery EMS or BMS detects a fault condition, it can cause an open
circuit to the battery. As the battery owner gets familiar with their new
energy storage system, this

Good to know Larry. I'm just trying to clarify what Dan is setting and what
outback is claiming.
Thanks

Howie,
We have many hundreds of Li battery systems sold and installed. Never had any
failure of PV controllers including Outback due to charging Li-ion.

Hey Dan,
Are you saying that OB is claiming that NiFePO4 batteries are smoking their
charge controllers? Do they say why? Is this also true of LiFePO4
batteries? If you wouldn't mind mentioning which battery manufacture you
are dealing with?
Thanks,

You state that the battery is a LiFe and Outback said it is a Nife bms.
Can you clarify please?
