As Mcgivor said or the update is that is all I use for my new clients who have reasonable temperatures and Schneider electronics. Outback soon will interface directly with the AES.It is a common configuration at this time Bill because I would not use anything that does not interface the BMS, battery, and Soc/temp directly from the battery manufacturer into the system over Schneider insight or soon Outback optics. The reason I do not think they will comedown is simply the cost of the materials in an LFP battery. They are going up lately. The BMS is pretty simple and electronics do tend to come down. I definitely would not buy a lead acid if i knew that this was for the long haul and that I could keep them at temperatures that are pretty well spelled out in the warranty. Partial cycling is what people forget to add when they cost an LFP battery BTW. Having accurate Soc, Not worrying about being full on a regular basis, = Priceless offgrid if you live there full time!I really respect what Rick has done but I could never use that system for a client and maybe that is what BB is referring to. I just looked, at close to 2 years I am still at 99% state of life from my BMS. A bit of math and at the rate we cycle, about 34 years left. I do live within an hour of Costco if the math is wrong My clients really like this battery, I mean really like it! Cheers!
