Re: [RE-wrenches] [EXTERNAL] Re: Lithium battery recommendation

[Jay via RE-wrenches]

Great info everyone snd it brings up more options for me to review.  I’m still wondering if there are comments about Fortress saying that you cannot add a battery to a bank that is 1 year old.  I just don’t understand lithium enough to know why. And most curious that no other companies I’m aware of say this.  If the voltage is very similar with age and just capacity is less then that is something that can be delt with via LVD settings. Given that most batteries are 5-8000 cycles and that roughly the capacity is 80% at that point is only an about 1% capacity loss per year?  That doesn’t make sense it’s an issue.  If there is a change in the voltage parameters, say the upper end lowers. A few tenths lower over years is a big deal? Doesn’t seem like it.  I’m not sure what would happen on the low end volts up, down? But why would it be a problem?

They can close loop communicate with several battery systems, and my sources say they’ve also got an EV charger that works with their off-grid systems that can be programmed to charge the EV when you have excess solar.   Kienan Maxfield, who’s on the list, is distributing Victron products, and he knows the technology well.       From: RE-wrenches <re-wrenches-boun...@lists.re-wrenches.org> On Behalf Of Michael Morningstar via RE-wrenches Sent: Thursday, July 13, 2023 7:12 PM To: RE-wrenches <re-wrenches@lists.re-wrenches.org> Cc: Michael Morningstar <mjmornings...@gmail.com> Subject: [EXTERNAL] Re: [RE-wrenches] Lithium battery recommendation   CAUTION: This email originated from outside of the organization.

I've never had an Outback system, going all the way back, that didn't puke prematurely and have issues. Discover AES and Schneider for the win. Once they are set up, they just work.    On Thu, Jul 13, 2023 at 3:20 PM Jay via RE-wrenches <re-wrenches@lists.re-wrenches.org> wrote: Hi all I’m Looking for recommendations for a lithium battery. 48v.  150-200 kWh. System is probably going to be open comm, as the system has outback equipment. That could change but probably not. Remote monitoring is required even though it is a site with people 24/7. So far fortress and home grid. Have been recommended to look at. Blue planet is just too expensive. And PS. Fortress says that you cannot add batteries after 1 year. This goes against everything I thought I understood about lithium. Any comments about why they say that? Do others say rhat?
