Greetings William,

Regarding a sealed charge controller; may the OutBack FLEXmax Extreme
Charge Controller be an option?...  Its spec sheet identifies it as
being IP54 rated (dust protected) and there is an optional fan kit to
help it run cooler.  Just a thought, if they are still being produced
and available.

Best regards,

----MATT

Friends:

Thanks for the input on this topic.  A few thoughts:

1. I could change the design from a vented 8k Radian to 4 sealed FX
inverters.  However the Outback charge controllers will still be vented.
This makes me think the best plan is an actively vented cabinet.  This
cabinet has a fan with filtration:

2. We have tried in vain to keep rodents out of a building or even a room.
Our best successes are in critter-proofing as small a space as possible.
Attached is a photo of an Outback installation with screen wire to keep out
wood rats that destroyed the previous installation by urinating on the SW
circuit boards.
