more setup details are needed, ie are you setup with ess turn on, if so adjust your grid setpoints and soc limits, or search for victron ess set manual, and set the ess up

i can´t reach my MultiPlus-2 via VE-Bus and MK3-USB.

everytime the same... i only reach the Venus GX and there is no relevant ESS settings.

Another Problem is the fakt that i have round about 6400 kW/p on my roof. i only can reach 1300W from solar... (2x5x40V-425W +1x6x+37V375W)

My Elecrican is not helpfull in this task... 1683137524181.png

To configure the multi with the mk3 you must connect directly to the multi with the mk3 and nothing else can be connected to the Vebus. If you are looking for ESS you must first load the ESS assistant in the multi. Set your grid code and run the assistant. Push the new configuration to the multi, then disconnect the mk3 and reconnect the gx device. Then and only then will the ESS menu populate.

you can also set up your Multiplus II via the remote VE config ?

thank you all for the fast response it was helpful to understand the problem in a better way...

today my electrican answers me. With his help ich can fix (hope so) the grid meter in the venus EES to zero. seems to work...

But he made the hint, that my Mppt is the reason for the limitaion of 1300W.

Its a MPPT 250 I60 -Tr

The PV-Input is limited to 250V max (i have 230V) and 35A (actualy 1260W and 5.6A)

The Multiplus is limited to 3kW.

I can´t see the problem with it...
