Samlex SSW-2000-12A Inverter

[geoffr]

A while back I posted a question looking for information on two inverters - the Xantrex Prowatt SW 2000 and the Samlex SSW-2000-12A.

I ended up buying the Samlex which works well, but makes a heck of a lot of noise This post is some information for anyone interested in the Samlex SSW-2000-12A...

For those that are interested here is what I've found:

• Background Noise for test: 25-30dB
• Inverter turned on, no load: 35-37 dB
• Inverter on with a good load (eg Microwave): 45dB

All measurements done with Android app on phone 1m from Samlex.

In the video below you can hear the "quality" of the noise from the fan at low speed (no load at ~ 5 seconds) and higher speed (load at ~27 seconds).

When talking to Samlex I was told the speed of the fan is variable depending on the load (it ramps), but I haven't noticed any difference once it goes to a higher level.
