MPPSolar PIP 3024GK 24V and lithium 8s
#1
Hi, im working on a powerwall and solar for my autocamper, and im in the configuration fase, but to me it seems that i cannot charge the lithiums up over 31.5V with this one (3.94 - using 8S) per cell, am i correct in assuming this is not possible with this unit?

if its not possible, then i would have to go with 7S for this unit

Links to the charge controller you are using would help drastically.

You are correct. 7s is better suited for that controller. 24v is not 30+v...

My apologies. I didn't put the title to the charge controller you're using. I just woke up and haven't eaten or had my coffee yet. I over looked it.

Potentially it should go to 31.5 but i wouldnt. I would stay at 7s to have a basic general setup. 8s on liion isnt really standard
