Firmware EG4_ceaa-0709 (Most recent)

@dtbaker61 
Thank you, I will share this with our team! I believe our team is working on adding Lithium Type 31 to the 12000XP as well.

@eg4eric , you might want to change the subjest line of this thread.... I don't think 0709 is the latest anymore, right ?

I know that the version ceaa-00080A I installed on a client 12000xp mostly fixed the open-loop float issue, but I don't know if you officially released that ?

I would suggest a dedicated thread with a general subject like "Latest 12000xp firmware and release notes" where you could log the date released, and major bug fixes and enhancements. It would be helpful for reference so people could see when their high priority issues are addressed, when (date), and what firmware number was...

It sure would be nice to have a "living document" for release notes and dates for issues fixed, or known outstanding bugs not fixed yet to help developers prioritize.

I have latest FW for 6000xp (ccaa-1E1414), but only Lead Acid works for open loop, there is no lithium type 31 to select.

Just FYI

@krzysiek_kta , you can make it work open loop with type=lead acid and managing by desired voltage setpoints.

That is exactly what I have been doing to top balance the cells in my wall mount battery or when there were some BMS comms issues.

Thx.

The firmware 0709 is still the latest available firmware. The firmware you were given has not a publicly released at this time.

I do appreciate the feedback regarding a dedicated firmware and release notes thread! Thank you!

well, if you want to release a fix for open-loop float, you might consider officially releasing the beta test firmware version ceaa-00080A, and or test/release a version that has a "selectable" choice for open-loop LFP managed by voltage.

I can say that the version ceaa-00080A does a decent job holding to float as desired, but does have a few occasional blips back up to Bulk under certain conditions. It's hard for me to tell, but it appears to occur on partially cloudy days when there are loads exceeding pv production and then the sun comes back out. The system seems to "re-bulk", and then drop to float.

I can live with current behavior, but it would be preferable if "rebulk/rebalance" only occurred after Vbatt<52.8, or Vpv <48 for more than 2 hours indicating "night". I'd hope for Vbatt to be maintained at float +/- .5 v afternoons when battery is full and sun is still out

Thank you for your input and feedback. I will share this with our team.

So, any idea when 809 might be released? A functional float setting sure would be a nice thing to have....

@solar_pergola firmware 080a is still "beta", and can be pushed on request, but is not available as standard update for some reason. This is taking WAY too long... I am going to have to consider changing my default off-grid installs to Eco-worthy if EG4 can't get it together soon.

I will just wait. 

It is super frustrating how at the core the 12000XP is a battery charger and it comes up really short. A battery charger that doesn't have an absorb timer, can't respect float settings, and doesn't have good settings if you are a LA user is pretty wild. 

My guess is this is Luxpower device and EG4 plays second and third fiddle when it comes to making changes like this. It would be really cool to see a clean sheet 12000XP EG4 equivalent. 

@solar_pergola This is exactly why I am considering Eco-worthy as a replacement... They are build by SRNE, not LUX. All of the LUX seem to have poor firmware for open-loop and completely moved away from support for Lead-acid. Both seem to rely on wifi/cell for config and updates which drives me crazy at truly off-grid sites.

As of now, we don’t have a confirmed release date. I checked about a week or two ago and was informed that the team is still testing a few things with the firmware before it’s ready for release.

Thank you Eric

@eg4eric WOW this is disappointingly slow for such an important thing! I know it's not your Fault Eric, but I do suggest that the EG4 marketing/sales team be aware that this issue is not just a "nice to have", it is a "must have" if you want positive reviews and future sales in the off-grid world.

I would suggest proof/video in release notes that a LFP-friendly CC/CV charge curve can be specified when running open loop with Voltage setpoints for Vend-of-charge and Vfloat

Typically, the CC charge runs up to Vfloat, and then switches to CV=Veoc to enable cells to balance as current is reduced approaching Veoc. for the remainder of the day, Batt voltage *should* remain close to Vfloat as long as PV wattage > Load

I hope that's what we are going to see ?
