question

1. what are your absorption and float voltages, and do they correspond to the recommendations of your battery manufacturer/

What are your "charged" criteria for 100% SoC?

2. No idea.

Thank u for your answer. The absorption and the float voltage are according to the battery manufacture. I think it is fake. I am wondering if i have to install something else to read the real SOC.

Hi @dpaparis

The only SOC you have natively onboard that Easy is the one in the Multiplus. The settings for it are in the General tab.

But it relies on seeing it's own Absorb V to reset the 'Bulk Finished' value. And it isn't seeing that regularly. Set the Multi's Abs V slightly lower than that set in the mppt (in Charger tab), so then it can register. There's a chance the V's in the Multi and mppt are reading differently, so allow for that or use DVCC to select a System V (see CCGX manual). Also make sure the Temp Comp values are identical in both chargers.

But a SmartShunt would be a worthwhile addition to your system. Much more accurate, but still will need tuning.

Your system seems to actually be running fine, fully charging each day.

Not sure what you're doing there with the VS? The relay for that is in the Multi, not the CCGX. And you have enough battery there to not need to autostart a genset with 2548W of load, especially with solar producing. Just as well it isn't starting, as it won't stop with 29V set as a stop V - you never get to that..
