[RE-wrenches] sunny island and lithium

[jay]

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.
