making mistakes so you don't have to...
Hi @MAS ,
Like probably all hybrid (all in one) they are noisy.
In a shed or so, not a problem.
The Revo II has a dust filter, depending on your environment you might need to clean this regularly.
For me, having 3 units in/close to our bedroom, I felt the need to silence them, and now they are whisper silent.
That's easy to do, with the right equipment.
Last one took me several purchases to have the good type fans.
Problem with most hybrids is the 80mm fans.
They are high quality, double bearing fans who can produce a lot of static pressure to suck out via restricted areas or blow into it.
And they do a great job, with matching noise level.
Only fans I found that have equal pressure and are silent, are the "high speed" silent wing 3, 120mm.
They aren't cheap, liquid bearing, and will last about 25-30 years.
I build a duct and have 2 fans blowing inside, and 2 fans sucking out.
Sucking fans are controlled by the Revo II (watch the original wire location, it's different from the standard 4pin)
Blowing fans have own 12v power supply and are thermal speed controlled.
Probably one would be enough.
One set of 2 absolutely is enough.
In the past I've lost a few Inverters (different brand, type, model) that had failing thermal management.
With -$1800 due to this, the $ 25 per silent wing fan suddenly is cheap
I'm a guy of better safe then sorry..
+ Result, the fans run on lower speeds, even more silent.
At full load, 4500w solar in, 3000 watt out, still whisper silent.
Total power consumption is less then the original 2 X 80mm fans.
