The temps build once the inverter power output drops because the fans are off. Once the temp (tRadiator1) hits ~149f two things happen: The inverter sends me a W013 warning and the fans kick on!.  In less than 60 seconds (usually 30 or 35 seconds), the warning goes away because when the fans are running the temp drops over 10 degrees. Then the fans turn off and the cycle begins again. It did this 4 times each inverter yesterday.

It seems like such a simple fix to turn the fans on when the temp hits 145f - THEN send a warning if the temps hit 149f.......

This did not happen last year. The only change to my system since then was when you guys updated my firmware to 508 in December while helping determine if my system was leaking power - I think you also changed the CT Offset to 20 - I have set it back to 0.

I live in Southern AZ , it was 109 degrees yesterday - the well-ventilated, but not climate controlled area of my garage this equipment is in was 94 degrees peak. Summer is coming! 

Do you expect me to just ignore the warnings since the unit is controlling its temps just fine? I already have Home Assistant only tell me if the W013 warning lasts more than 60 seconds (and that has not happened yet).

Please propose changing the fan-on trigger to include temps a couple degrees below the warning temperature - IT JUST MAKE BASIC SENSE!

• 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.

Would like to see in "working mode "AC FIRST" have the options to operate via "SOC" or "VOLT" with conjunction of "time range".

EX: If you have rainy day. Didn't reach optimum charge for the day. Your system can be setup to switch to "AC FIRST" at a preset "SOC"  and time range.  This way you can preserve your battery power incase of a "utility grid" failure and have backup before the next 🌞  Sun rise!

This would help me out. This is for ppl that wishes not to charge their batteries with "AC Charge"

Thanks.

• Based on ceaa-0507
• 1. Optimize the issue that battery voltage high or BUS voltage high alarm may occur when the battery is fully charged.

Type= Li-OpenLoop
Vend-of-charge= 56.2(default), and Vfloat=54.0(default)

The result should be a CC-CV curve hitting the target Veoc hit once a day, held for 0 time, and settling to Vfloat. Veoc flag can be reset to detect "night" as any time that PV voltage < 50vDC

I would like to be informed when this bug is addressed, and suggest that it is propagated to to all inverter firmware. I'd love to see it start with the 12000xp and 6000xp since I have several clients installed off grid with these, and I'd like to see proper charging, safety, and maximize battery cycle life.

Let me do eg4 a favor and announce it since apparently they don't have time to announce it. Well its out if anyones interested!

Looking for validation of my plan to update ol' 12000xp from ceaa-0202 to ceaa-0507 offline please.

12000xp currently exhibits seemingly random bouts of fast fan syndrome when solar power is connected. Internet connection not available. 

Finally figured out to logout from EG4 Monitor on Android to access Firnware Update. Downloaded two files consisting of ceaa-0507. 

The dongle serial number appears in my Bluetooth devices list and I am ready to pull the trigger to install the update via Bluetooth. 

I plan to put ol' 12000xp in standby first. 

Kindly validate my plan as we all know what happens when firmware updates go awry and it ain't pretty. 

Many thanks,
