Насчет того что PowMR6.2 постоянно крутит вентиляторы без нагрузки и пытается дозарядить батарею, хотя он заряжена на 99%, написал производителю и получил ответ. Если кратко, то так и должно быть. Даже на полностью заряженной батарее инвертор пытается поддерживать ее заряд (хотя зачем это для lifepo4 непонятно). Поэтому инвертор периодически подает на батарею в районе 1 ампера(судя по БМС). Из за постоянно крутятся вентиляторы, потому что данная часть греется даже при таких незначительных нагрузках.
Собственно переписка:
Hello,
Thank you very much for your email.
I’ve recorded a short video showing how the inverter works in idle mode (without load and with the battery fully charged). There are no error codes, and everything seems to be working fine, except for the constant fan operation. The fans run continuously whenever the arrow on the screen indicates power flowing from the inverter to the battery.
During charging, the inverter becomes even noisier, which indicates that the temperature sensor reacts to the charging output power. However, even when the charging power drops to 0, the fans continue to run constantly.
When I switch to SBU mode, the fans stop. Similarly, when I set the charging source priority to solar only, the fans also stop running constantly. It seems the inverter continuously tries to charge the battery (Lifepo4 52V100A - GTK). No solar panels.

Dear Customer,
Thank you for your email and video.
It seems that the inverter is operating normally. Even though the battery is near full charge (99% SoC), the inverter continues to charge it with a very small current to maintain the battery in a fully charged state.
The fans are running as a part of the cooling process because the internal components of the inverter generate normal operating heat during this time. The fans are necessary to protect the inverter and ensure stable, continuous operation in a safe temperature environment.
Currently, there isn’t a setting to control this small current charging. However, if you notice that the battery is fully charged, you can manually switch off the AC circuit breaker to stop the inverter from charging the battery with mains power.
If you have further questions or need additional support, feel free to reach out.
Best regards,
Isabel
