Reply To: V5 Stack SOC and charge cycle differences

[M.]

Some days with good PV power are gone. Yesterday the stack was completely charged to SOC100, all four batteries.

The charge process with Firmware V27 is straight forward. No CCL dopdowns, if the batt. voltage is above 55V. The step from SOC~90 to SOC100 was done in a few minutes, with V22 over 30 minutes because of CCL 5A.

After SOC100 was reached, CCL was set to 0. The four batt. began to balance internally. The SOC goes to 98% while CCL stays at 0.

Have a look to Home Assistant Log Screenshots to see the details.
