Hi the collective hive of information.
I am in the middle of commissioning an Orion TR Smart 12/12-30A on a VW T6 Camper van. The system doesn't seem to be triggering that often, and even after a couple of hours driving the Lithium batteries are not full.
All default settings have been used, but the start battery is regularly at 12.3-12.5v.
Are the default settings too aggressive, do they need to be dropped. If so any recomendations. I have done various searches and running second battery charging with Euro 6 engines seems to be a dark art with little information about what a good set of settings should be.
My instincts as opposed to science or knowledge is to:
Drop Input Voltage Lockout to be 12.1v / 12.3v. After starting the engine and idling the starter battery is regularly at 12.2v, so restarting shouldn't be an issue at 12.1v.
Setting Start Voltage to 13.2v
Setting Delayed start to 12.8v
Setting shutdown voltage to 12.7v
Any guidance, are these values too low?
