  • 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.

I have never had any issues with my 1200xp inverter its been working for almost a year now and recently just updated to the 0508 firmware and now its fans ramp all the way up and then it triggers over temp alarms even at night! I think there is an issues with the temp cofig Celsius because at night when is cold to the touch, data shows like 62 deg Celcius.

@eareyes20 
Could you provide your inverter's serial number? 

I can attempt to roll back the firmware to 0507 and see if that fixes the issue.

it looks like ceaa-508 introduced a bug, and did NOT include a fix for open-loop lithium charge control. What will be in 509 ? When ?

...I really need to see a fix that results in a LFP-friendly charge for generic open-loop charge control by voltage that results in the desired CC-CV charge curve. I expect to see battery voltage rise to some Vend-of-charge (56-59v), and then relax to Vfloat (53-54v).

firmware is holding battery voltage at vBulk after charge SHOULD end and settle to float. This is not good for batteries, BMS, or safety.

I see, I will share this with our battery technicians. At the moment, I don't have a date for another the release of the next firmware update.

@eg4eric News on fix for charging open loop by voltage ? I'd be happy to test. seems like developers should be able to spot the coding difference between the 6000xp which is working correctly, and the 12000xp which is not ?

260116 6000xp correct Veoc to Vfloat
260116 12000xp stuck at Veoc
