Victron DC-DC charger settings.

Good afternoon guys.

I posted a while ago regarding some issues with my charger/battery and I’m still trying to resolve them.

would anyone be kind enough to post the settings used for a victron 12-12-30 dc/dc non insulated charger with a 110 agm battery.

I’m struggling with getting charge and just want to check im on the right settings.

Thanks

For reference these are my current settings

Hi Chris, did you manage to resolve your charging issues. I have just installed the same b2b but im not convinced its charging my leisure battery as it seems to continually state 'Charge disable de to input voltage lockout and engine shutdown detected'
 
FYI . . . the default settings are shown on the Victron APP DEMO files.

Thanks for the reply it seems to be charging now.. Out of interest i notice the lockout and restart value is 10.4v/10.5v. Mine defaults to 12.5v/12.8v. Why the difference?

not sure, (those are screenshots from the APP)

though 12.5v/12.8v seems a bit high.

thats saying it will shut off below 12.5v

and not come back on till over 12.5v . . . .

but its always best to run an IGN or BCM feed in.

if its working then just keep an eye on it.
 
Hi all, I was just about to start a new thread and then saw this one. Just back from my first trip after a new engine and new battery. The dc dc charger kept turning off and I worked out it was due to the lock out and restart values. But every now and then the input voltage drops to around 7v which in turn switches off the charger. @Dellmassive any idea why that would be?

This is normally volt drop caused by too thin a cable, or melted fuse holders, or bad ground connection.

Post pics of the fuses and DC-DC connections, and cable runs etc.

And if you can get some shots of a multimeter showing voltages with the engine OFF and with the engine ON.
