Re: [RE-wrenches] sunny island and lithium

Thanks Jerry.  It turns out the client would like more AC power so the inverter upgrade is looking probable vs just a battery swap.  I’ll head out soon to review the system and figure things out.  Jay On Jul 15, 2025, at 7:52 PM, Jerry Shafer via RE-wrenches <re-wrenches@lists.re-wrenches.org> wrote:  Jay, Wrenches, Fortress works great, no closed loop from any battery manufacturer and the SI Inverter, l got a great price on the fortress, we should talk Jerry On Tue, Jul 15, 2025, 6:43 AM jay via RE-wrenches <re-wrenches@lists.re-wrenches.org> wrote: HI All, I might be inheriting a 12 yr old SI off grid system, that has a dying Absolyte battery.  I know there have been some discussions on the SI and lithium. I’m just trying to understand what the options are with closed vs open loop, basically can it be done.  If I do get the project, I will happily pay someone who’s done all the hard work for the education to tell me what the programming steps are.  And at what point does it make sense to just remove the SI and install a AIO? thanks in advance. jay _______________________________________________ List sponsored by Redwood Alliance Pay optional member dues here: http://re-wrenches.org 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 There are two list archives for searching.
