Not sure about others but I am certain that the AC180 takes that much power when the devices connected to the power station (loads) draw very little or no power. This was tested by putting a meter at the wall outlet and plugging the AC180 into the meter. Although there were several devices plugged into the AC180 at the time, I ensured that none of them were powered on during the test (using the AC180 as a backup UPS). I measured 800watts over 24 hours on the meter. Regarding the amount of power consumed while recharging from 99% to 100%, I don’t have exact figures but it seems like it was pulling 200 to 300 watts. Since the cycling occurred relatively frequently, that explains the reason for such high power consumption. I hope that clarifies my observations.
I left some time to test before commenting, let’s see.
1.- The fans at the speed that you have configured it makes more noise than two PC’s that I have in the same room. Maybe the fans are of low quality, in terms of sound, or they are still at a higher RPM than I consider to be quiet.
2.- Every so often, it goes up to the maximum RPM as when it was switched on from a stopped state and then goes down to a constant and fixed speed. Why?
3.- If we don’t solve this problem by the firmware, can I change the fans for others that are quieter and have the same (or higher) air pressure? What brand/model or technical characteristics are the fans installed in the AC180?
I have to test it some more time, but I don’t think we have gained much with the previous firmware change, because this one also increases RPM every so times and on addition it makes constant noise during 24h…
Anyway, the effort to try to solve the problem is appreciated. I hope we will succeed. Thank you very much.
Well, several days later, I still have the same opinion: what’s the point of having the fan on 24h if at regular intervals it also increases the RMP generating a high fan noise as before?
I think what was searched with the 24h fan on was not to generate more noise than the fan constantly running, but now it also generates loud noise sometimes and constant moderate noise 24h a day.
I think we don’t gain much with this update. any ideas on how to improve this? Is it possible to revert to the previous firmware?
@bluetti_curichinatogmailcom We will push a firmware for you in 6 hrs, then you can revert to the previous firmware.
You will receive a version update to 2078.99 (actually 2078.06). After you complete the update, your version will actually revert to 2078.06 and will continue to prompt you to upgrade to 2078.99. At that time, please leave a message to let me know and I will delete the “2078.99” version prompt on the background server.
Ok, I already updated it. You can delete it now. Thanks you.
Everything is ok, thanks you.
Just an update in case it is helpful for anyone. I also tested an AC60 by leaving the unit in “UPS” mode (AC inverter on) with no load (nothing plugged in) and discovered that the unit used about 360 watts over a 24 hour period. Probably not going to work for my purposes as the power draw seems excessive for a UPS.
@Bright The fan is noisy when using dc power. If you use AC power while the DC power is on, it suddenly becomes quiet. Is there any solution to the problem?
