I have forwarded this to Schneider. They gave me a case number in 30 minutes. I disagree that "all" Li batteries need this. Obviously simplyphi does need LBCO to be increased. The LBCO delay does help at 10 minutes from 2 minutes default BTW.
I have not had your issues with tech support. Certainly room to improve but not much different than Outback over the long haul. Let us agree to disagree. I find Schneider to be the best for my requirements, 2nd is Outback. I do not use simplyphi. They are just too small of an offgrid battery and easy to damage with XW and Radian. My last on this subject.

Hysteresis and time don't fix the fact that once the batteries shut off before the inverter, the entire system is inoperable, with no charging available from the PV. It creates an absolute failure, that requires a manual reset, and there is no reason for it. It should be an easy firmware fix to allow LBCO to go above 48. We've used other brands of inverters and had excellent results with extremely high efficiency charging, noticeably reduced gen run time, etc. We can set the autostart on the generator to start higher, but as soon as there is a problem with the generator, we're snow shoeing in to save the house. Already done it 3 times this past Winter, so no, this is not a hypothetical problem. Also, I haven't mentioned Schneider's abysmal tech support throughout this problem. Zero on site phone support, but we might get a call back a week later, and then the tech can only read from the manual: something we've already done. I dropped Schneider many years ago when they brought out the terrible TR line of inverters. Those had 100% customer dissatisfaction. They have yet to regain my support, and now after this latest experience, I have to refuse to even service systems with Schneider equipment.

Curious because I will send this in again. I did last time and they said to make sure the config person knows that you can also set the default LBCO hysteresis from 2V to 10V and the LBCO time from 60 seconds up to 600 seconds. Zero probes here for me with Discover AES and Fortress with Schneider electronics.

There is no external monitoring or comm, just an output breaker on each battery that can be reset if the internal BMS ever shuts down for any reason. We've done several sets in new systems, and as battery replacements with older Outback equipment. Simpliphi provides a nice programming cheat sheet for all the brands of inverters and charge controllers. For smaller systems, the LiFe Blue batteries are great. They have the best monitoring (simple blue tooth to a free phone app) and they are the only Li+ battery that has a solution for cold weather charging that I'm aware of. Other battery companies have just given us the shoulder shrug and tell us to install the battery in a conditioned space. Not a good answer for many off grid systems in the mountains. I'm not a huge fan of Blue Planet; if their battery is over discharged, it requires a 48 v dark start. I also did not find their enclosure to be NEC code compliant to connect conduit to. We had to modify it to allow a 2" KO. Cable routing and connections internally are also awkward. Its just a computer rack cabinet repurposed for batteries, but it does have pretty blue Lights (which we disconnected at the customer's request) Finally the comm system is based on the E-gage, which was never designed for off grid and depends on a constant router and internet connection to monitor. That is another deal killer for some remote projects. Internet connectivity is great when available, just the monitoring can't be dependent on that connection. Their tech support was good though. Beware that Schneider inverters LBCO can't be programmed over 48v, which is a deal killer for most Li+ batteries. We currently have a system that we are adding a relay to shut off AC output, that will be triggered by the charge controller. That is just an amazingly kludgy solution for a really dumb problem: not allowing higher settings of the LBCO. Until Schneider releases a firmware update, they are not even being considered for future projects.

The newer FXR series are. Considering one only needs to change slightly charge voltages, duration, etc. to meet BI recommendations, it's a mystery why Outback states that older FX inverters are not compatible. Outback states this in a tech note about using LI batteries. On 8/9/2020 5:40:39 PM, drake.chamber...@redwoodalliance.org [7] wrote: P.S.
