150/70 MPPT Equalization current percentage not working

I hadn’t thought about it that way. Here’s a post I put up the other day. I use Node-RED to drop the DVCC charge current to 2A when the battery reaches 99%. It also gradually reduces the charge current from 100A down to 20A as the voltage rises from 13.6V to 14.2V. I’ve got a bunch of 12V batteries in parallel, and they take ages to settle. This setup works well just another approach to consider.

But if you use ESS the solar is not throttled. This is my flow to control the charge current. I filter the voltage and range the charge current from 20-100 amps between 10:30 AM and 4:59 PM. Outside those hours the charge current is 0, so the solar starts charging in the morning. None of my batteries on my 12V system can communicate. When the voltage rises from 13.6V to 14.2V the output changes from 100 amps down to 20 amps. You can set this to what you need to make sure you don’t get a battery …
