I am installing an Orion on my boat for charging the lithium House bank and already have a multi plus with the secondary charging port going to my start battery… Will the secondary charger trigger the auto engine stop/charge and turn the Orion on and if so can I wire it to work on the ignition switch only and turn off the engine shutdown detection?
I'm assuming Primary charger of starter battery is engine alternator
Multiplus DC output is secondary charger of starter battery.
Orion can be configured to run automatically based on the charge voltage it sees from the starter battery/multiplus/alternator. At other times it will be off, drawing standby current only. This can be with or without engine on auto detect.
It can be wired to only turn on when switched on by the ignition switch using the H terminal.
It will stop charging when starter battery voltage drops below the value you set.
So if I understood your question, the answer is yes
If you have or install Victron Connect on your phone, one of the features is the demo library. In that you can select the Orion charger you're interested in and see/configure the selected charger.
This would turn the Orion on.
Yes you can prevent this by setting the Orion to only charge when ignition is on, look at the H pin exple in the manual.
