I have a domestic 4 kW solar system. I have just added a Victron multiplus II 48v with a pylontech US 5000 battery. The bulk and absorption lights are flashing on the Victron multiplus II and the load and the bulk on the app are going up equally the same kilowatts as the solar panels output, My electrician is not familiar with Victron. Would anybody be able to advise? Many thanks here’s a photo of how it’s been wired in. I hope it makes sense.
Is the system configured at all?
Wich multiplus is it? 3k/5k? With a 3k multiplus 2 4k pv inverter is to big
Where is the et112 connected to? Looks wrong on the picture?
Where is you bms connected to? On your drawing it says ve bus on multi, thats wrong should be can bms on cerbo
Please get help from a victron reseller/installer, you could potentially damage a lot…
Thanks for the response
The multiplus II is configured and it’s a 5k the PV inverter is 3.6k
The ETA112 is in the fuse box. Pretty sure that’s installed right, my bad drawing.
The installer is experienced with Solar and batteries (give energy), just not with Victron products.
Couldn’t find any detailed wiring schematics for domestic system, lots of off grid diagrams I’ve got.
Many thanks
Pwfarnell, section 7 there is a perfect example drawing similar of your system except the et112,
the et112 should be xonnected to usb on cerbo via a victron usb to rs485 interface
From the drawing you made i see a lot of wrong connections!
Have you read the Victron Pylontech compatability and set up notes

Also get your settings sorted on the GX.
Do t worry about what lights are flashing whatever. Use the GX to tell what is going on.
