ESS Scheduled charging not working / multiplus 5000

Hello,

I am new comer there. I use my system Victron Mulitplus 5000 / MPPT 250V / 60A, since last september and all was fine.

since few days / weeks, the scheduled charging of the battery (LG resu10) during the night is not working anymore. I scheduled to charge my battery at 35%

there was no changing on the set up, and i did try many option but i cannot load anymore the battery with a schedule charging program.

Can someone help me to solve my issue ?

Thanks.

When you say you cannot load the battery, do you mean the color control no longer has it listed as a device?

Thanks Alexandre to help me.

I still see the battery listed as a device in the Color control.

But the battery is not charging. for example if the battery is at 20% and i request a charging at 35%, using the grid. the battery is not charging and stay at 20%

@Cyril Calvignac Can you force it to charge to 100% by setting it to '"keep batteries charged"' in the ESS menu on the GX?

ejrossouw has a valid point though, is your GX set to update automatically?

I have exactly the same setup and have no problems after any updates. Can you plse post some pictures of the settings. Note - This is not a Victron supported battery for this model inverter. Lots of things to look at. What is the battery health %. When last did you upgrade ESS assistant? Does DVCC work correctly as there was a mention some older battery firmware versions are not comptible with it. Indeed see if it can be force charged as suggested by Alexandre. Are the battery fuses ok? What voltage does the battery measure at the battery end and also inverter end? Have you tried resetting the battery etc. etc.

@Cyril Calvignac Thank you for the screen shots. I'd propose to turn off STS and SVS. Use only the battery as master. What is the current battery parameters at?

@Cyril Calvignac Did anything change in your system e.g. automatic firmware updates? What does the system show as battery monitor in the remote console under system setup?

Yes thank you. Glad to hear. All looks fine. With smart batteries there in only a need for one source of truth, the battery so yes, turn all other shared setting off in dvcc. Mine works perfectly like this.
