Thanks Jay I have not used I-E batteries & This is the direct result of my Kauai charity case client online shopping. She was sold an undersized/over promised system: 50% of req’d PV & basically one days storage of T-105 style batteries. She has burned up 2 sets of batteries and has had several of installers try to steer her to total replacement with a variety of systems. She has an Outback VFX3624 dual inverter system, no problems there & ½ the PV she needs. The equipment originally installed in a mini shed a ways from the house that could have been installed under a high covered porch on the ocean side of her house. Her health is an issue, she lives free in a house that was a gift [she got to build it], & there is no utility available. She is not able to afford me to fly there [ I just moved to ID & have started my new house here additionally] & I have to say she has run into a # of opportunistic installers that think she is easy pickings. She needs 1200 watts of additional PV & 760-900 AHR @ 24 VDC of LOW TO NO MAINTENANCE long life battery & moving the power equipment to under a covered porch. Anyone with integrity free to assist? Please contact me off line for a discussion.

But if this is a charity case, I don’t know how you can even think about them. First off, while yes you can take them down quite deep w/o damage, but then you also don’t have much storage either. So I don’t agree with the logic, I feel its based on trying to sell a smaller than useful battery requiring more generator run time. 400 amp hr at 24v nife is $7700 plus shipping. 800 amp hr L-16’s are $2200? really good ones with 2500 cycles to 50% are $3200 I sure don’t recommend them. Let me know if you want more info. jay
Begin forwarded message: From: "Dana" <d...@solarwork.com> Subject: [RE-wrenches] Battery Watt hours FLA VS Iron Edison Batteries Date: October 14, 2016 at 6:55:43 AM PDT To: "'RE-wrenches'" <re-wrenches@lists.re-wrenches.org> Reply-To: RE-wrenches <re-wrenches@lists.re-wrenches.org> Good Morning All, I have a charity case client that needs 760 to 900 AHR at 24 VDC. I have installed HUP Solar One Batteries for 20+ years and do not have any experience with the Iron Edison battery. My client went to Iron Edison & was told that 360 AHR at 24 VDC would cover the same AHR as a 760 to 900 AHR in FLA. I understand you can use the IE deeper typically than a FLA. Math is math to me & how I have sized [successfully for years] Is there something I am missing or has my client been misinformed? __________________________________________________________ Dana Orzel Great Solar Works, Inc - NABCEP # 051112-136 <mailto:d...@solarwork.com> d...@solarwork.com - <http://www.solarwork.com/> www.solarwork.biz O - 970.626.5253 F - 970.626.4140 c - 208.721.7003 "Responsible Technologies for Responsible People since 1988" _______________________________________________ List sponsored by Redwood Alliance List Address: <mailto:RE-wrenches@lists.re-wrenches.org> RE-wrenches@lists.re-wrenches.org Change listserver email address & settings: <http://lists.re-wrenches.org/options.cgi/re-wrenches-re-wrenches.org> http://lists.re-wrenches.org/options.cgi/re-wrenches-re-wrenches.org List-Archive: <http://www.mail-archive.com/re-wrenches@lists.re-wrenches.org/maillist.html> http://www.mail-archive.com/re-wrenches@lists.re-wrenches.org/maillist.html List rules & etiquette: <http://www.re-wrenches.org/etiquette.htm> www.re-wrenches.org/etiquette.htm Check out or update participant bios: <http://www.members.re-wrenches.org/> www.members.re-wrenches.org
