Two MPPT, two different charging phases

Two strings on my roof: 4 solarFabrik (Bosch) 245WP monocristal (parallel/serie) and 6 SF-175 CIS (parallel), each string managed by a separate MPPT 150/65.

When I reach 100% SOC one shifts to float the other remains on absorbtion for quite a while.

Normal or bad settings? if so how do I change the settings with CCGX?

Tks, Lionel

Assuming battery voltages are where you expect them to be, It is normal and expected for them to arrive at float at different times. It does not make a significant impact on performance.

There is an upcoming firmware improvement for precise synchronisation of the charge states of multiple SmartSolar MPPT's via Bluetooth being tested.

It is not currently possible to change MPPT settings via CCGX. For now it requires VictronConnect.
