[RE-wrenches] Inverters & BLM for Lithium?

[Jeff Clearwater]

Hey Folks, Having just brought another 2 tons of lead to a Caribbean island that has no lead recycling capacity (nor orientation to ship them off once they are kaput) I'm really wanting to offer Lithium on the next job. Where do we stand in terms of inverters and BMS -  off-the-shelf that we can offer?  The Radian manual says the charge cycle can be configured to Li but when will we see an integrated and optimized inverter/charger with individual cell BMS ? SMA?  Outback?  Magnum?  Schneider? Let the race begin! Thanks, Jeff Larry Crutcher, Starlight Solar Power Systems wrote: $360/kWh is a good price. Can you share the brand with us or email me off list? We sell Li-ion (LFMP) at our store but I include a CPU, protection solenoids, battery capacity meter and video display. My dealer cost is quite a bit higher than you were quoted.

We were just quoted a 50KWHR at 48 volt battery pack with enclosure and BMS for $ 360.00 per KWHR or $0.36 per watt hour. _______________________________________________ List sponsored by Redwood Alliance List Address: RE-wrenches@lists.re-wrenches.org Change listserver email address & settings: 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 List rules & etiquette: www.re-wrenches.org/etiquette.htm Check out or update participant bios: www.members.re-wrenches.org Marco, This year I began designing and installing Lithium battery banks, specifically LFMP type Li-ion's. The performance benefits and cost per cycle makes it the battery technology I recommend first for all mobile and most off grid systems. GBS has test discharged their LFMP battery to 100% DoD @ 0.5C rate and made more than 2000 cycles with 80% rated capacity remaining at end of test. Contact me off list if you want to discuss more.
