Hello All,
I am looking for 2 - Laing D5 solar 090 pumps [PV direct 12 vdc] with flanges ants bleeder ports. Conergy sold out and Innovative Solar who bought the Dankoff line now does not carry them. Any suggestions? Please contact off list if you supply. Thanks Dana Orzel Great Solar Works, Inc www.solarwork.com E - d...@solarwork.com V - 970.626.5253 F - 970.626.4140 C - 970.209.4076 I will be the shift in how the world uses power! - Dana Orzel From: re-wrenches-boun...@lists.re-wrenches.org [mailto:re-wrenches-boun...@lists.re-wrenches.org] On Behalf Of William Miller Sent: Monday, February 01, 2010 11:18 AM To: RE-wrenches Cc: RE-wrenches Subject: Re: [RE-wrenches] Back-up from large grid-tie system. Kelly: A big a** generator and a transfer switch. William Miller PS: Seriously, I have seen projects like this and rarely is there a natural subdivision in the power distribution that allows one to back up a portion of the loads. Backing up a huge power demand, which I assume this is, is best done by rotating machinery.

It uses a Blue Sky 3024DiL charge controller, a pair of SunXtender 250 A-hr AGM batteries (24 volt configuration), and a Xantrex Prosine 1000 inverter. We have been using this system for powering "events" and getting some good marketing from the activities. Everything has worked out well, and the system is not being used now and probably won't until March or April sometime. We have let the system fully charge the batteries through bulk/absorption and now float. The float conditions are 26.4 V and 2.0 A at a battery temperature of 21 deg-C. My first question: is it alright to let the batteries float every day for the next 6 to 8 weeks, or should I disconnect them from the rest of the system until we are ready to use the system again? My second question: since the 3024iL can perform an equalization, is there a safe equalization procedure for these AGM batteries? - Peter Peter T.
