Hi James, I second Jay's SNAP-Fan recommendation. They are the highest quality DC fans that I've seen. Here's their website: http://www.snap-fan.com/index.html You might be able to use those Grainer fans on direct PV, but you will have to find out what the fan's motor specs are. Many "12

TOM: I've not worked on a project with an array-to-inverter cable run of that length. I am assuming the wiring will be underground. I would consider using DC surge arrestors on both ends of the PV Output Circuit(s). Also, make sure you have a good grounding scheme for the array. Regards,

Dearest Wrenchies, So here is the situation, we have a customer with a passively heated kiln for drying lumber. Basically it is a greenhouse. There is no supplemental heat, or power at the site where it is. When it begins to be heated moisture will be driven from the lumber, which needs to be exh

Morning Wrenches, I will try to find the ticket. Maybe The installer built a small shelter to fully insulate the inverter, let me look into it. It will be a couple of days though, as we are moving to a new office building. SMA had special circumstances to bring the cold weather units to Canada.
