<br>
I might be inheriting a 12 yr old SI off grid system, that has a dying Absolyte battery.  <br>
<br>
<br>
I know there have been some discussions on the SI and lithium. <br>
<br>
I’m just trying to understand what the options are with closed vs open loop, basically can it be done.  <br>
<br>
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.  <br>
<br>
And at what point does it make sense to just remove the SI and install a AIO? <br>
<br>
thanks in advance.<br>
<br>
