2008-12-24 Thread Peter Parrish
I don't think this topic has been dealt with in this forum. Ocassionally we want to use a single inverter with two or more strings, each string being loaded by a single sub-array.

Title: Re: [RE-wrenches] Skystream 3.7 experiences? Yep, I agree. FYI, Proven has finally given up trying to sell us on the idea of roof-mounted turbines - at least when it comes to me. ;-) The people in SF are full of crap, of course, but I was being nice in my comments to the general group. N

Hi Kirk, About 75% of our installations need to consider the effects of salt air. We install along the coast of Maine and in the Bahamas, so there are additional issues of temperature extremes which can compound problems in a not-so-well thought out system. From using silicone grease for termina

Hey Matt. There is much interest in the "urban turbine" these days, in part because it has a catchy ring to it. Proven has installed many urban turbines in the UK, all on low towers or roof mounted and all have reported poor production by comparison to the traditional tower top installation in th
