Multiplus 3000/12/120 recharge up to 85% and stop.

Good morning everyone,

I have a simple system installed on my Camper.

The Multiplus 3000/12/120, combined with an SmartSolar 100/50 and an Orion 12/12/30, interfaced on a Cerbo GX together with a Smartshunt 12/500A. The battery is a 200Ah LiFePo4 with integrated BMS. The temperature and voltage sensor of the Multiplus and Smartshut are installed correctly.


The MPPT manages to bring me the recharge up to 100%, then maintain and compensate with the loads present at the moment.


The Multiplus unfortunately not.

Fast charge up to 85% after changing to float.


I can't figure out where I made the wrong settings and why if all the devices read the SOC from CerboGX it's like making an exception.


Thank you all.

HI


David

Possibly it is a voltage thing.

If other devices are providing power to the battery, the inverter can go to float as it is not doing anything.

Thanks for the reply Alexandra,

unfortunately it happens in the evening, when the MPPT is in stand-by.
