simple switch for charger off Multiplus 3000 12/120/16

Hello there, can i put a simple on/off switch to turn only the charger on/off by Hand? Or must i buy the blue Power Panel to do this in my Motorhome?

I have a Mk3 Dongle either and i know i can do this with the Victron Connect App with my Phone, but this is not a option for my Motorhome

Greetings

Hi @hmo

You can use the 'charge current control' assistant for this:

Hmm i think this is not for my Setup.


I have 200 Ah Lifepo4 with buidin BMS. When we stay at our Place on the Camping-Place, we have everytime Shorepower. So the Lifepo4 will stay every time by 100 %. We will use the powerassist for our Climatic and the 4/6 A Shorepower for the coffeemaker a.s.o. . If the Lifepo will charge imediatly and everytime, it is not ok.

So i think, when i switch off the charger by hand with a simple switch, the Lifepo4 can do some work to discharge. My BMV 712 will have an Eye on the SOC and so i can switch on the charger to load when the soc went to low......


I dont understand how can this be done with an assistant like the above.....

I think you have two options

1. The charge current control mentioned by Daniël.

If you connect a switch to AUX1 and close it you will disable the charger bur you also can use shore power and power assist for your loads.

2. Ignoring AC IN.

If you close the switch connected to AUX1 you will stop using the shore power completely.

Hello Herr Lange,

the 1. Option with the switch on AUX1

(If you connect a switch to AUX1 and close it you will disable the charger bur you also can use shore power and power assist for your loads.)

That's exactly what i want....


Thank you for that....Now i mus have a deeper look how to realize that...
