The charge scheduling is not working in an ESS configuration

The configuration includes a Multiplus II 48v-5000W in ESS with Pylontech US3000C batteries, without solar panels, only in back-up mode.

When I program a time slot for charging, in the scheduling, nothing happens, it continues 24 hours a day as if there was no such programming.

What to do ?

Thanks

Check in ESS|Settings you have not got Keep Batteries Charged selected and have an appropriate value for Minimum SoC like 10 or 20%.

To answer your other query, yes you can have a higher degree of automation with Node Red, see the Modifications section of this forum, but it is not very easy to use for a beginner and you should not need it to overcome your current problems.

I would concentrate on getting the right settings in ESS first.

Thanks but I don't find the option "Keep Batteries Charged".

Concerning the power consumption I installed a power meter and I found 0.8 kwh/24H and the Victron Energy Website management indicates 1.4 kwh/24H which is almost twice the value found.

Concerning the NodeRed, how do we connect locally to the Victron installation?

Google for victron large firmware node red and node red victron. There are special nodes that allow access to the Victron setup. https://www.victronenergy.com/live/venus-os:large

in Remote Console go to Device Manager|Settings|ESS|Mode.

You want either of the Optimised options, not Keep Batteries Charged.

I don't think a 0.6 kWh difference in power readings in 24 hours is significant.
