I have two Apex 300 now. I am awaiting my Hub A1 to really use them, however I have them on just directly plugging in some computers and lights in my home offices.
The draw on them is very low 200-300w max at anyone time.
However, I have noticed the Fan(s) are ON always. They never go off, regardless how cool I keep an office room with a portable AC unit.
I have not found any “settings” for this.
Any ideas? Will the Fan(s) always be ON regardless?
Thank you,
Randy
Hi Randy, I have one of the UK versions of the Apex and my fan does go off under low usage, but the fan is on more often than it is on my AC300. I would say it is on half of the time. It is quite warm in the UK so room temperature is about 24 degrees Celsius. One of the fans seems to rattle a bit so I will most likely swap it out at some point.
Thank you for feedback. Based on your comment, I think I will try next to reduce the load even more of one to see if Fans go OFF at any point, and maybe also no load to see what happens. Yes, my AC300 fans also behave different than Apex300; those fans only come on when load gets higher or solar input grows
Not sure if this would make a huge difference, but I do run my Apex 300 mostly in off grid mode with solar charging. I did notice the fan coming on when I was charging from grid.
Я имею станцию АС200PL
І у меня тоже такая же проблема,что когда станция включена в сеть,то вентилятор работает постоянно.
Я долго пытался объяснить в техподдержку,что бы проверили, может нужно просто проверить алгоритм работы в прошивке,но всё бесполезно 
Потому я думаю что Вам врятли помогут
Попробуйте без подключения к сети, может помочь
You can try putting the switch to silent this seems to help, it will limit the charge to around 500-550w in but that’s more than enough for your low load, I have noticed when plugged into the grid the fans run more than they should while consuming more power even in standby with the AC output off, I believe this is an issue with the firmware but I can’t say for certain.
У меня в бесшумном режиме вообще вентилятор работает все время,когда станция подключена к сети.
Я тоже думаю что проблема в прошивке,но как это доказать и исправить,не понятно
The AC300 also had an overhead when connected to grid, and the voltage on both power stations is increased to match the grid voltage. I prefer to run my electronics at a lower 230V so I use smart plugs to enable charging at off peak times.
Yes sounds like it’s some default settings, but I do not understand why this would be the way if there is no load or charging on the unit just because it’s connected to the grid, this will cause added load for no reason on something that’s designed to be helping you and saving money not increasing the cost.
Я с Вами согласен.
Но поддержка bluetti ,Я так понимаю не хочет в это вникать
Я с ними 8 месяцев переписуюсь,но всё бесполезно
Interesting, I will try as well because my reason for buying 2 apex 300 is to wire them to my panel through a 50amp breaker and cable as designed but if it just sits there and pulls extra power from the grid because it wants to run the fans for no reason then what is the point?
The “Charging Mode” switch does change the Fan speed. Even when it is not connected to a Grid connection nor a Solar connection, changing Charging Mode from Silent to Auto increases the Fan speed (noise).
Eventually I will be moving my Apex 300(s) to a room where I will not hear this additional noise, but I find it odd the Fan(s) don’t seem to adapt to Load, rather than a constant speed regardless of Load. My AC300 did not behave this way.
I will not be able to leave in Silent mode. I will need it to charge at higher watts during off-peak Elec rates. One of my objectives here is to never use on-peak rated Elec
Still waiting for my HUB A1 to arrive. Does anyone in Canada have one of these yet??
I am not keen on the charging mode switch on the unit as the App is not able to override it, when you put it on silent and forget and then try to charge remotely at a faster speed you can’t override it. They should have used a toggle button with an LED identifier so you have no fixed position, and then it could have been overridden in software.
Since the latest updates I am now able to reduce the charging Amps below 10A so it’s now possible to control the charging speed by that setting rather than use the charging mode, however I am not sure if it reduces the fan speed if a lower current is selected.
With my AC300 I never thought about putting it into silent mode or turbo mode, I always controlled the current as needed. I think that is a better way to manage the unit. It would be easier for me at least if each mode was just linked to a current rather than an ambiguous label.
I just received my Hub A1 recently… connected up what they sent me for a test and yeah the battery fans are on even when its not charging.
Multiply the sound across 6 units and yeah its loud
Привет
Как на сейчас обстоят дела с вентиляторами?
Так само всё время работают.
Или может эта проблема решена?
