Re: [RE-wrenches] Enphase v. string inverter

Marco, The last I heard the NREL was testing enphase vs. a string inverter, they were also suppose to test enphase vs. A competitors module level mpp tracking. Not sure if that performance test is complete yet. I have seen 1 independent unshaded test ( potentially biased ) which IIRC showed

I have seen the top performing contractor in my area sell behind a chiminy and under a tree, claiming 10% more using Enphase than unshaded.    Darryl --- On Sun, 10/10/10, Jamie Johnson wrote: From: Jamie Johnson Subject: Re: [RE-wrenches] Enphase v. string inverter To: "RE-wrenches" Date:

Re: [RE-wrenches] Mac compatibility with Modsine

2010-10-10 Thread Hugh
Greetings, Does anyone know if newer Macintosh computers are still incompatible with Modsine inverters, and how about Mac loptops ? I have been using Macs since the mid 1990s and much of the time plugging them into 'mod-sine' inverters such as the old Trace U series and DR, and various l

The main advantage of Enphase is the module level monitoring. However, the increased output due to partial shading can be significant. I was at a 6 year old PV site this week, and a tree had grown up near the base of the roof. Branches were casting a few minor shadows on the array, but wa
