Hi All
As per title
Is there a QUICK way without a faff to enable disable charging functionality of Multiplus II , other than VE Configure , MK3 etc. ?
If not , why not?
Thanks

QUICK way to enable charging function Multiplus II ?
VRM, Cerbo with touch screen bothe have a quick way to enable charge. Usually it's on by default.
I think you are referring to " Inverter Mode " , yes , I am well aware I can change this via VRM , to Inverter Only , Charger only , On and Off and very quickly indeed with a click of a button.
Unfortunately this is not what I asked.
I asked about enabling / disabling charging function, as per original post, please refer to the picture as well.
You just need to use VEconfigure once, at installation, to adjust settings according to your battery requirements. Then just feed AC power to AC IN to start charging. Can't be quicker :D
It is not so quick when I need to do this multiple times when required based on my setup. Takes good few minutes to interact with it , when I want it enabled or disabled.
The quickest way that I know of is to make 2 settings files for the inverter using VEConfigure 3, one with charger enabled and one with charger disabled but everything else the same. keep copies of these on all devices you use to connect to VRM. Then go into VRM, menu>Device List and at the bottom is a remote VE Configure button, press this and it allows you to upload either of your preconfigured files. This still takes some time but avoids the need for the hardware mk3 dongle.
Another option is to use Node Red to change the charge current to 0Amps, I have used this on a lead acid system but there are reports that with a managed lithium battery it gets overridden by DVCC. Search in the modifications section if you wish to look at this option, here is one recent post.
I already use VE Configure to achieve this , this is what I am trying to avoid, as it is a bit of a faf.
I will try via Node Red see if I can make it work on my system via chargecurrent settings.
Can't understand the reason not to be able to control this with a simple interaction.
We can control the behaviour of the inverter via VRM , click of a button , to the extend it can have much more complex consequences, turn off inverter for example ...
Why not integrate this , put another switch somewhere , with a tick , " Enable Charger " ?
@Teloth Have you looked at the list of assistants?
Yes, but there is nothing obvious that will make life easy after using the assistant , to be able to change this externally when I want to enable / disable manually for the future.
Just like you can change inverter mode with a click of a button in VRM
You may use the "charge current control" assistant :
it can change the charge current based on the state of an auxilliary input. You can the control this input via one of the cerbo's relay.
This assistant can fully disable the charger, like VEconfig does ,whereas with node red you can only set charging current to 0, wich does not fully disable the charger :
@Teloth Could you use the "allow to charge" function of the 2 wire BMS assistant?
