I have an Orion 12v30a isolated charger with an mppt 75/15 along with a BMV-712 Monitor and smart shunt.
I have a fridge connected to it currently and the voltage of the battery has lowered to 74%. When i drive the vehicle the Orion goes to bulk for a few minutes @ approx 22A.
after that few minutes the charge rate drops down to a few amp and even 0 but the charger states it is in BULK.
I have tried various options for engine detection smart alternator, Regular and user defined.
I get various results for both but currently i only have it set to user defined with a start voltage of 13.60.
If I disable engine detection i get 22A charging in bulk BUT it keeps going if I turn the engine off.
input lockdown voltage lock-out is 12.5 - 12.8v.
All negative loads go through the smart shunt on the loads and chargers connection on the shunt
positive goes direct to battery.
Vehicle is a 2016 triton which is a regular alternator though this is the worst profile in my findings.
I tested the input voltage from the alternator/primary battery and it is 13.60 when the engine is started.
Any ideas?
