Fake High temperature Alarm Quattro 10,000VA

Hello,

when I turned ON the AC input 1 or AC input 2 in my Quattro 10Kva, the red light " high-temperature warning " blinked, but this warning is fake and the Inverter is cold and working well.

- this fake warning appears only when the battery is full or between 97 to 99 %, if the batteries need to charge from the Quattro no problem, and no warning appears.

Cerbo Version 2.89, Quattro V497, Smartshunt V4.08, ESS mode.

If the Power from AC1 or AC2 is used for Load or to charge the batteries, no warning light, and no problem. but if the batteries are full and have low load consumption this is the problem. In ESS mode, the "Keep batteries charged " option creat to many fake high temp alarms, but "Optimized without BatteryLife" with minimum SOC = 90 to 95% is ok and working without Warnings.

batteries used : SUNLIGHT RES- 6 -SOPZsS - 965 A


Any Help Please?


Regards

some updates about my problem :

when the load decrease from approx. 5000 w to 1000w or increase from 2000w to 4000w rapidly, at this moment the Red LED flashes for a few seconds and the High-temperature Alarm appears.


I think the problem is from the PTC or NTC inside the 2 transformers , these sensors send the wrong value when the load power change rapidly.

What type of temp sensor is used inside the 2 transformers in Quattro 10,000va?

Is it PTC or NTC?

Any help please ?

I'm not sure if this helps, but I'm having this issue as well. Interestingly, it went away after the first few minutes of operation but has come back at times. I took this unit apart to make a repair, and another user mentions that the ribbon cable under the upper front panel might be loose. https://community.victronenergy.com/questions/110855/new-quattro-15kva-shows-temperatur-alarm-led-witho.html
