question

I think i needed to change the first 2 dipswitches to 1: ON, 2: OFF

Now the Multiplus does turn on and i can connect to it with the Raspberry Pi. The only problem i have is that i cannot change it from "ON" to "Charging" and when i change the grid input limit from for example 16A to 10A, it doesn't change anything and resets to 16A immediately.

Is this normal?

Can you see the Remote Console via the Pi on your local network and is it showing your Multi in the device list?

I can access the remote console, i have added the Pi to VRM.victronenergy.com and it is showing the MultiPlus as a connected device. I also can see battery percentages, Watts that are pulled from the grid etc, i just can't set the state (On, off, charge), or the grid amperage limit

Ok, so if you go to VRM and select device list. There is a Firmware update button. First thing I would do is select that and make sure you have the latest firmware for your devices?
Then select the Settings> General from the left hand menus, there you will see a slider for "Inverter/charger control" make sure that is ON. Then in the Dashboard screen there is a square Icon top right with a couple of sliders, click that and you should have the controls you need??

I can't update it because i think the firmware is too old. I don't know to what version i can update (maybe via the VEFlash tool?)

I had setup the Inverter/charger control and i can see the controls, but clicking on the mode is not responding and if i change a different current limit value, it says "loading" but then is set to 16A again

It does seem like a firmware issue, is yours a 230V or 120V version, small microprocessor or large micro?

230V

I have no idea if it is a small or large micro processor. Does a picture show it?

Ok I think from your original firmware this looks like old(small) micro? Have a look at this:-
https://www.victronenergy.com/upload/documents/manual-VE.Bus-firmware-versions-explained-EN.pdf
You need to use VE Flash to upgrade to v209 I believe. Do check this yourself to make sure you are happy. (It is possible to brick your device) and by all means get a second opinion . The first 4 numbers of the new firmware need to be the same so 1908xxx so you are looking for 1908209
Have a look for the file here, you may need to create a (free) account if you don't have one:-
https://professional.victronenergy.com/downloads/firmware/

I read that file many times but i don't understand a lot of it. How do i read the firmware version and how do i know if i have the small micro controller.

I have a free account for the firmware but still, no idea how to know what firmware i need to download

What is the difference between Non-assistant or Assistant firmwares? I now have 142 installed but i can't find what type of firmware that is

I think this is the starting point:-
Family groups

18 No VE.Bus

19 VE.Bus - old microprocessor, 230VAC

20 VE.Bus - old microprocessor, 120VAC

26 VE.Bus - new microprocessor, 230VAC

27 VE.Bus - new microprocessor, 120VAC

Your original firmware started with 19xxxxx

Okay, so 19 is my processor, 08 is the type, but then there are 2 options:

1908159 - Non-assistant

1908209 - Assistant

What does Non-assistant or Assistant mean?

Assistants are extra pieces of software that you can add in with VEConfigure, you may or not need them? Your VRM page shows v209 as the latest available.?

I just noticed that so i will install 209 tomorrow. Let's hope i can set the inverter via the display then

One other thought.... After you removed the DMC, and then through the Remote Console > Device list > Multiplus > Advanced > ... you should(could) try Redetect and Restart VE Bus system??

Without DMC is there a jumper missing?

What jumper?
I am going to update to version 1908209 now but before that i needed to make a settings backup via VEConfig. I did see the checkbox "overruled by remote" was checked. (General > Shore limit)

Does this need to be checked?

So, with the DMC dis-connected did you try Redetect and Restart VE Bus system?? (Remote Console > Device list > Multiplus > Advanced >)

I don't have it where you point at but for my it is as follow:

Menu > MultiPlus Compact 12/2000/80-30 > Advanced > Redetect VE.Bus system [Press to redetect]

Also i have Equalization (don't think i need to do anything here) or Restart VE.Bus system (which i also did).

I have redetected the bus system and it can connect (i do get a temperature sense error but has probably nothing to do with this).

After doing the redetect it does show me an "edit" arrow at the "Input current limit" field and i can change the value, but after clicking the "accept" icon, it doesn't do anything and shows 16.0 as value (even when i change it to any other value lower than 16)

I don't think i have that

This is the MultiPlus menu list:

Its there on the 3rd screen down "Input current limit"

I think it is time to use VE Configure and check all settings after firmware update. Make sure your battery charge settings are still as you wish? "overruled by remote" should be checked. In setting up VE Configure from scratch again there may be some further clue to what is going on.? (If it was me I would set all the DIP switches back to default, all OFF, and sort out the programming with VE Configure)

Thank you for your help but i discussed it with my dad and i think the best solution is to keep the DMC as well. (Install it in the garage close to the MultiPlus). If they are on a place with a different grid limit than 16A he can change it in the garage, but also if the Raspberry Pi doesn't start or has crashed or something he still can change the values or turn on / off the inverter

I don't think with all the dip-switches to off, he can use the screen and the DMC to both setup it right?

The DIP switches 1 and 2 are only used for setting type of battery charge you require? So, they should at least be set for the type of batteries you have?

In the manual it has different meanings:

https://www.victronenergy.nl/upload/documents/Manual-MultiPlus-Compact-2000-230V-EN-NL-FR-DE-ES.pdf

Here on page 21 and up

I do have the compact, but the file is also the "Manual-MultiPlus-Compact"

Sorry... i misread your message, but i think i will install both so my question is solved.

Thank you for all your help!
