Есть вопросик по PowMR 4,2кВт:
Сборка 8х280Ah, BMS JK B2A8S20P-HC
На инверторе выставлено напряжение Bulk 28,8V, Float - 28,4V. Доходит до Балк, опускается до Флоат и на этот держит заряд, тут как бы все норм, но он постоянно гудит (работают вентиляторы), а это бесит. Это нормально для него?
Отписывался по данному вопросу в другой теме. Продублирую тут, на всякий случай. Списался с производителем, вот переписка и его ответ:
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), t
he 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
