Re: [RE-wrenches] Power One Micro inverters

Thanks August, appreciate the heads up on wiring cost and potential communication issues. Sounds like Power One isn't quite as fine tuned as Enphase yet. I'll compare cost with Solar Edge with maximizers. Mahalo, Roland Shackelford Vice President NABCEP CERTIFIED INSTALLER Renewable Energy Servi

Re: [RE-wrenches] Power One Micro inverters

I haven't used them yet but I would suggest to consider also SolarEdge, as they have a solution based on string inverters and optimizers. Regards, Roberto Kruse Sistemas de Energía 2013/12/11 Roland Shackelford > Aloha Wrenches, > > Any experience and recommendations using Power Ones Aurora M

Re: [RE-wrenches] Chloride batteries

Hi William; My now apparently orphaned copy of Maui Solar Software has Pacific Chloride Brand batteries listed in its data base that are industrial flooded lead acid batteries. They have very similar performance parameters as other fork lift batteries like the HUP. I don't have cycle life i

Re: [RE-wrenches] Power One Micro inverters

Hi Roland, We’ve installed around ten Power-One micro systems with mostly good results. All in all, I’d say the installation is very similar to an Enphase M215 based system if you are familiar with those. As William mentioned on a separate post, the cabling is a bit expensive but otherwise simil

Re: [RE-wrenches] Power One Micro inverters

My supplier cuts Aurora cable to length. I found the total cost to be just about in line with Enphase when trunk line and other components are considered, maybe a bit less per-watt depending on whether you are using the 300W or 250W. I haven't used them yet, but I'm about to order for a 27 unit jo

Re: [RE-wrenches] Power One Micro inverters

Roland: I haven't used the product but I priced it for one job. I recommend you verify your expense for AC interconnection cables. You might have to buy an entire spool. This could bite you in the ass later. Wm From: re-wrenches-boun...@lists.re-wrenches.org [mailto:re-wrenches-bo

[RE-wrenches] Power One Micro inverters

Aloha Wrenches, Any experience and recommendations using Power Ones Aurora Micro? I am designing a system using Panasonic 240W modules (72-Cell). This is a high end home that needs all the power I can fit on its roof. There are multiple roof pitches, orientations along with shading. I feel either

Chris SAM software from NREL is also free and relatively easy to learn. Give it a try! I have found it pretty good at predicting financial viability of a project. Bill On Wed, Dec 11, 2013 at 6:52 AM, Mac Lewis wrote: > Hi Chris, > > I have a spreadsheet that I made a while back that will g

Hi Chris, Another free option might be RETscreen: http://www.retscreen.net/ang/version4.php OnGrid and Clean Power Finance Tools are two popular paid options, both offer free trials I believe. -August *From:* re-wrenches-boun...@lists.re-wrenches.org [mailto: re-wrenches-boun...@list

Re: [RE-wrenches] Return on investment information

Hi Chris, I have a spreadsheet that I made a while back that will give a 20 year cash flow and internal rate of return. It's set up to work with the market in Colorado with Xcel REC payments, and Federal tax credit, but you are welcome to use it and modify it if you like. Send me an email and I'
