HI Drake, I think it really depends on what inverter you have, what the size is, what features you want and why do you want lithium?
For example to me, as they are black boxes, I will only use one that has a physical external monitor, not only a web based, which at this point is pretty much Discover. Also Discover is the only battery that actually has a closed loop, ie it actually communicates with the inverter control system. Currently that is SolARk and schneider. And Discover is the only one of the more common popular batteries that is an actual battery OEM and its a big OEM that has been around for something like 75 years. Simpliphi is the easiest drop it replacement. No monitoring, but its sealed so no mice/rodents/bug issues, no comm to inverter. Blue Planet is too much hype to me, only has internet based monitoring, is on open cabinet which I worry about the issues above, no communication to inverter. I do like that it is a modular approach so its lighter to assemble. There are a number of others too. Before I spend tens of thousands of someones money I always check to see how long the company has been in biz, what their size/$ etc. And I look to see how the corporate structure is set up, ie how big is the tech department? Look at Blue Planet for example, big list of names, only 1 tech person. Good luck with the wild west of batteries, Jay > On Aug 9, 2020, at 10:12 AM, drake.chamber...@redwoodalliance.org wrote: > > Hello Wrenches, > > What is the best Li-Ion battery to use with an off grid system? > > Thanks, > > Drake > Athens Electric > > -- > _______________________________________________ > 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://lists.re-wrenches.org/pipermail/re-wrenches-re-wrenches.org > > List rules & etiquette: > www.re-wrenches.org/etiquette.htm > > Check out or update participant bios: > www.members.re-wrenches.org > _______________________________________________ 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://lists.re-wrenches.org/pipermail/re-wrenches-re-wrenches.org List rules & etiquette: www.re-wrenches.org/etiquette.htm Check out or update participant bios: www.members.re-wrenches.org
