Re: [RE-wrenches] Li Replacements for Lead-acid Bank

[Jay via RE-wrenches]

I would add that there is a big range in LVD in lithium batteries. 

Simpliphi has a really high one, others much lower which do work with older 
equipment and their LBCO settings.

Re: [RE-wrenches] Li Replacements for Lead-acid Bank

[Maverick Brown via RE-wrenches]

For LBCO, you can wire the inverter AUX port to the inverter Enable port (there 
is a jumper installed by default). Then program AUX for a higher set point. 

It would be great if battery companies added an AUX port as a warning before 
shutting down.

Re: [RE-wrenches] Li Replacements for Lead-acid Bank

[Jay via RE-wrenches]

I agree with John

A pretty simple fix is to install a relay on the AC side controlled by the AUX 
of the inverter.

Re: [RE-wrenches] Li Replacements for Lead-acid Bank

[John Blittersdorf via RE-wrenches]

Matt,  I have several systems with the same mix working ok except that the
low battery cutoff can’t be set high enough to shut down the inverter
before the BMS shuts off the battery.  Have had to manually restart the
batteries.  Problem only occurs if generator doesn’t start as programmed or
manually started.  I install an iota 48v charger wired into the dc bus to
jump start the system in worst case scenario where charge controllers are
also shut down and generator can feed in bypass mode to provide a hot
outlet for the IOTA.  The IOTA charger also serves as a small backup
generator input pathway without having to change any charger settings in
the inverter.

Re: [RE-wrenches] Li Replacements for Lead-acid Bank

[Foxfire Energy via RE-wrenches]

I was told early MX charge controllers (pre-2011) would lose their mind if the 
BMS for lithium Batteries shut down under load.. something about they weren’t 
designed for that kind of surge.. but I think the issue was corrected in like 
2012..
