I concur with Daryl, noise is at most comparable and doesn't exceed any other inverter. I just take care to keep it off the bedroom wall (like any inverter)..

<div class="PlainText">Hi Kent,<br>
We have two 8 kW and four 12 kW installed in the Bahamas. We installed<br>
one in a bedroom closet about two months ago and the client is still<br>
happy. There are some relays and occasional hum but to my ears, they<br>
are less noisy than the XW+ and certainly no more than the Radian. The<br>
initial startup is the only real noise, with the startup fan being the<br>
loudest.<br>
We are really happy with these inverters so far. Their monitoring<br>
platform is still a work in progress IMHO and they are working on being<br>
able to control settings remotely like Optics RE. My next job is on<br>
Abaco with a 12 kW. They are eay to install, self contained and are an<br>
excellent match with LiFePo batteries. Be aware the 8 kW does not have<br>
a battery disconnect. The 12 kW does.<br>
<br>
