Multiplus 3000 - Secondary Battery Settings?

Hi there,


I have a Multiplus 3000 230V 16A and installed it in my Motorhome. I’d like to connect the starter battery to the secondary output on the Multi. So that it can keep it topped up. I could not find any settings on this via the VE Configure software? I could see in the manual that the maximum output current is 4A but what is the maximum output voltage? Is this something that I’m able to set?


Thank you in advance

There are no settings for that. It will simply charge a battery at a maximum of 4A up to Float Voltage.
The secondary battery Voltage must be the same as the main battery Voltage.

Thanks, really appreciated.

I have a start/stop battery so if I set the the right Float Voltage then I should not have any problems.

Do you know if I need any kind of protection (fuse?) in that circuit (maybe from the alternator?) or is that integrated in the Multi?
