EG4_ceaa-0709
2026-03-01
- Based on ceaa-0607.
- 1. New Feature. Generator Charge Time Scheduling--configure specific time windows for generator-based charging.
- 2. New Feature. Generator Quick Start-- remotely triggers a 20-minute generator run cycle from the monitoring system.
- 3. New Feature. Generator Warm-Up & Cool-Down Logic-- automatic 2-minute warm-up and cool-down on every start and stop. Cool-down duration logged in historical data Separate configurable cool-down timer available for generators with built-in requirements.
- 4. New Feature. Max AC Input Power Limiting-- reduces charge power when AC input exceeds a configured threshold.
- 5. New Feature. EG4 Battery Remote BMS Update Support.
- 6. New Feature. Quick Charge Function-- enables faster battery charging when conditions allow.
- 7. New Feature. Configurable Discharge Resume SOC-- after reaching cut-off, battery must recover by a set margin before resuming discharge. Default: +5% SOC or +2V.
- 8. New Feature. State of Health （SOH） Reporting-- SOH data for closed-loop lithium batteries now included in Excel history exports.
- 9. New Feature. Battery Warning Buzzer-- audible alert triggers at battery warning voltage Disabled by default, silent if battery-low buzzer setting is off.
- 10. Improvement. Absorb and Float voltage minimums for lead-acid mode lowered from 50V to 48V for broader compatibility.
- 11. New Feature. Smart Load Power Display-- smart load data is now visible on the LCD DATA- LOAD page and the web monitoring portal.
- 12. Improvement. Multi-firmware update process now requires only one system restart, regardless of how many updates are queued.
- 13. Improvement. Three-phase overvoltage protection updated to evaluate line-to-line voltage （e.g.208V）instead of 2x phase voltage （240V）for three-phase systems
- 14. Bug Fix. W04 warning not clearing when switching battery type from lithium to lead-acid Now it clears correctly on type change.
- 15. Bug Fix. Generator is unable to charge when Smart Load mode is active simultaneously Note: Enable GridAiwaysOn to use Smart Load and generator charging at the same time.

so.... does xxx709 include a fix for setting a "correct" charge curve for open-loop (no comms) Lithium ? i.e. user defined end-of-charge and float voltage ? asking because I do not see it in the release notes above.
I'd be happy to update and verify, but hesitate to take the time if this fix is not included in this release

I have not heard an update on this, but I will check.

I believe for the 2nd feature, it's for the Gen Quick start on the Monitoring system.
For the first feature, I'm not 100% sure. Let me ask about this.

Glad to see the updates!
I'd like to ask for a feature request for controlling the fans. I have 5 12000xp's and I notice while charging from solar the fans will constantly ramp up to high speed and then back down. I'm looking for a slower ramp up and more of a steady speed.

We appreciate your input and your feature request for fan control. I’ll forward your suggestion to our engineering team for consideration in future firmware updates.
In the meantime, if you notice any unusual behavior, please let us know.

My vote is that the TOP priority fix for next update should be open-loop charge control for LFP. This is not a "nice to have", it is a "MUST have" for safety and battery life. Existing behavior holds batteries at vBulk all afternoon after batteries are full, and never settles to a safe float voltage.
EG4 finally fixed this for the 6000xp, so the question now is WHEN will it be fixed for the 12000xp ?
Let's have a DATE, or at least a target, for when this bug will be addressed ?!

@eg4eric Thanks Eric!
Also- just tested the gen switching- Folk, they fixed it! It’s not perfect but it’s good. There’s still a hiccup when switching to batteries from gen, but it’s small and switching from batteries to gen is seamless.
Thank you EG4!

I agree with you 100%. This should be a TOP priority. I see the same problem with my set up regarding the open-loop current charge control. There should be a way to taper AC charge current limit down baseg on SOC or battery voltage.

@dtbaker61 Hey there, I am in the same situation as you. I have some non-comms/dumb lithium batteries. I have figured out a work-around with the use of SolarAssistant. Basically, on the automation page, I created an automation that changes the adsorption setting to a nicer float voltage once the batteries hit, in my case, 56v. The next morning I have the same automation set the adsorption voltage back to 56v based on the "solar progress" value in SolarAssistant. It's been working well, although not set and forget. Once a week I disable the automation so the batteries are allowed to balance for a few hours. Such a shame EG4 has not addressed this issue for over a year now.
I started using solar assistant so I could incorporate a victron shunt and use it to control when my 12000xp switches back over to the grid. That automation has been working flawlessly all winter. If you're interested I can share some screenshots of the settings I used in these automations. If you're not using solar assistant already it would be required for this to work, very easy to setup. Cheers 🤙

I understand, I will get back with our team about this. I know this has been reported but I have not had an update for this. I apologize for the inconvenience!

Is it doing the same thing with the lights flickering or what exactly is happening?
Posted : March 20, 2026 9:20 pm
3/17/26 - I was able to have the development team upload Beta firmware ceaa-00080a for the 12000xp
- looks like system finally stops CV charge after about 10 minutes, and settles to Float. I am guessing they are testing for a little while longer, but then rolling it out soon.
I would HIGHLY recommend that notice of this update availability be proactively emailed to ALL 12000xp accounts as a highly suggested update since it could provide significantly longer life and better end-of-charge safety for LFP batteries.
Q: Batt-type still must be set to "lead-acid" for open loop on the 12000xp.... which is fine, but I'm wondering why this different
than 6000xp that has a Li type 31 for open loop LFP ?
