Battery charging

Hi, new user and first time poster.

I have two 12v 100ah lithium batteries connected in parallel for 24v. With the inverter off and no other load I can’t seem to get the batteries out of bulk state?


It’s only fed from two small panels but the battery voltage just seems to fluctuate between 26.4 and 26.6 and doesn’t appear to go higher?


When loaded, it’s a 1000w 24v inverter feeding just 300w of led lights.


I can’t seem to be able to post images. Am I doing something wrong? Would a shunt or other device give me a better understanding of the battery charge state.


Thanks

Hi @Michael8626

We will need more information.

What MPPT? How small are the panels? VOC?

What is the target voltage? 28.8?
