[RE-wrenches] ] Dusty off -grid conditions

[Dana]

I did a system in costal Costa Rica right after Y2K flopped with equipment previously  installed for the same in Colorado.
Despite a concrete building with screened windows we had geckos galore getting into the Trace SW4024 inverters. As the geckos got fried & died they turned acidic on the circuit boards creating an even bigger problem for the electronics.
I would suggest sealed conditioned building or marine or totally sealed equipment.

Hi William

Sounds like Baja. 

With such limited details, I'd consider conditioned space via AC unit. 
It would keep the batteries cool, inverter, CC, and ancillary units dust free. Then you can use the equipment you want. 

But if that isn't an option, the XW series has a much better design for dust. The fan doesn't blow across the power electrics, but behind it over the transformer and FET heat sink.

Peltz power.
