North Central Texas Setup Just about to turn a year old!

Well I now have another "issue" Dust, Dirt & Humidity. Arrrrrgggggggg

Posted in the general inverters forum and nobody wanted to go down that road. SEE Original Post HERE

There is a layer of dust all over everything.  That is easy to get rid of with a air blower and shop vac.  What concerns me is the ultra fine stuff i found.  My concern is that this dust is collecting on the boards and parts inside.  Being in Texas that is "usually" not a big deal until you throw in a high humidity day(s).  That in turns into a hot, wet blanket covering all of the boards and advancing heat damage and degradation.

I put foam tape on all of the doors and that helped but just.  I figured out that South wind that is almost non-stop was driving the dust and dirt past the doors and into the shed.  My solution was to put walk-in freezer hanging door. 

I also added a professional grade wood shop dust vacuum to try and filter out the as much dust & dirt as possible. 

 I am planning on making extensive use of the humidifier feature on the EG4 24k mini-split I am using to keep the humidity in check while we get through this hot Texas summer.  

After two weeks of observations I have noticed a lot less dust.   The first week I blew/wiped down all of the surfaces then closed and locked the doors with the curtain in place, and left it for a week straight and there was barely any dust visible on the black surfaces, including the filter case.  The filters were just a bit brown tinged.(if forgot to take photos).  The hanging plastic is a bit cheesy, however i'll cut them with a straight-edge and I'll glue 2" washers to the bottom of each strip (my neighbor has a paint bucket full of them) to act as weight to make them hang straight.

I am still hoping to get some answers from folks on this board,  on what they think the best way to clean inside the inverter.  I wouldn't think it would need to be done more than once a year.  My thought was to power everything down, take off the covers and blow it out with air.  Not up close but close enough to get the dust airborne and into the vac and filter.
