Trace SW noise levels. [RE-wrenches]

[Todd Cory, Bald Mt. Solar]

IF you are going to install one of these inside a living structure I suggested a
well vented (for better heat control) insulated box. I did this on a installation
with a SW4024 inside the house. I lined the box with carpet which really helped.

This homeowner is very sound sensitive and it greatly reduced the noise impact,
however the lower frequency "ticking" in search mode still drives her nuts. (She
also strongly dislikes wind up or battery operated clocks that tick.) I showed her
how to shut the unit off and to my understanding she does this every night now.
This 4024 was an upgrade of a 2012 which was much quieter in search mode.

The best advice I can offer... and if I had it to do over, I would have just let
the batteries be cold and put the inverter outside in a "power shed". While
inverter noise can be somewhat mitigated, is is next to impossible to totally
remove this and for sound sensitive people, best to put it in another building.

Hope this helps,

Todd Cory
