Re: [RE-wrenches] 30 kW Inverters

Peter, The Sunny Tower will work at 240VAC three-phase, with no modifications. Since it contains 6 regular SMA Sunny Boy's, they are each configurable for 208, 240, or 277VAC. I don't see any reason why it wouldn't work in a "high leg" configuration also. Another advantage of the Sunny Tower is

[RE-wrenches] solar roof lift experience?

Hey gang- anyone have any success (or horror) stories with regard to panel lifting equipment? I have considered a home-brew cart on a ladder, looked at some products made for comp shingles, and saw some fancy-schmancy European stuff at the shows. Just today I was hit with a marketing email from

Re: [RE-wrenches] 30 kW Inverters

Can't, that's why we need 2ea inverters with 50 kW on the roof. 25 kW on each of the two inverters. Peter T. Parrish, Ph.D., President California Solar Engineering, Inc. 820 Cynthia Ave., Los Angeles, CA 90065 CA Lic. 854779, NABCEP Cert. 031806-26 peter.

"we have to split the AC output into two separate services." How can this be done with a single inverter? Mark Frye Berkeley Solar Electric Systems 303 Redbud Way Nevada City, CA 95959 (530) 401-8024 www.berkeleysolar.com _ From: re-wrenches-

Re: [RE-wrenches] 30 kW Inverters

Hi Peter, I don't have history with the PV Powered's but they have a 30 KW I've heard good things about. A couple of Solectria 15 KWs would make a nice balance between "single inverter" and redundancy and ease of install. 2 or 3 Fronius IGPlus 12 KWs would also be a good solution. Power

[RE-wrenches] 30 kW Inverters

We haven't designed/installed a 30 kW-dc class system for some time now (last time we used a Xantrex PV 30) and are currently investigating what is available in terms of single inverters with 240V 3Ph output. Our customer has enough roof space to for 58 kWp of modules, but we have to split the AC o

HI All, For plug in watts/PF meters is there a better or more accurate one that anyone recommends? I've tried the Kill-a-watt and seems to work and be pretty accurate, but haven't compared it to many others. I've been testing some CFLS vs LED and the PF is way better on the LED. For us of
