Hi,
We have a Multiplus II 48/5000 working with 2 x Solar MD Lithium batteries SS4143 ( 2 x 14.3kwh) as a backup unit, with the intention of installing PV in the next few months. There is a Cerbo GX integrated into the system.
For whatever reason, the system is not charging the batteries to 100%. The "charged" SOC on the system has gradually been reducing over the past few weeks. At the moment, the system will not charge above approx 80%.
The BMS is working and set as the default battery monitor.
I have tried adding and removing the ESS assistant, thinking that selecting the "keep batteries charged" option in ESS will resolve the issue, but with no success.
Would appreciate some input on what I may not have configured properly?
Thanks,
Nick
