Smartshunt Consumed AH out of sync.

Hi all, hopefully last question.


So I fully charged the batteries (3* 12v 115ah lead acid in 24v) hit the sync on the shunt 28.6v, 1% tail.

Discharged and partially charged over the next few days maxed out at -92ah consumed and subsequently recharged over the next day. Shunt hit sync with -34ah left (28.6v) and the mppt shortly went into float.

Logged the ah lost so to speak and tested again over yesterday and today. 0ah consumed down to 34ah back up to 11ah hit float on the mppt. (Shunt didn’t sync this time) consumed again circa 34ah overnight recharged today and hit the sync threshold with 14ah on the table. Mppt in float around 20 mins later.

The only other thing that’s throwing me is the Soc. when down 34ah it should work out around 10% discharged the shunt was still saying 94% charged. So something is amiss somewhere I’m just unsure what setting to change?

Would appreciate any pointers. Other than that the system works no problem.

How did you connect 3 batteries at 24V?
