photo-2024-06-18-16-28-57.jpgDear all I am trying to optimize my system, BMV-712, CerboGX, Inverter 1600, MPPT Solar, Shunt for wind power, engine alternator, 1 starter battery victor AGM 110H, 2 service battery Victron AGM 110H connected to 4KWH (4 units 1KW each) ultracapacitor sirius). the question is how do I set up min voltage 11V-11.5V and max voltage 13.5V for relay in the battery monitor? what I am trying to achieve is to ensure I can use the ultra capacitors many times voltage goes below 12V (panel, water maker, regriferator or raymarine system - auto pilot, axiom, ais, radar, sonar) and even at 90% energy storage cannot use anytning. here is what I confirured but not sure is the right thing. I have victor battery protect, Argofet and galvanic isolator!! hahah all victron.. my system is 12V 16AMP

For what it's worth, please keep in mind that technical support for your unit will come from your authorized distributor, this Community is not an official support channel. I suspect no one here has chimed in because this is an unknown configuration - to the best of my fairly extensive knowledge, no one has ever tried using a BMV on a system with ultracaps before (and it's obviously not a directly supported configuration) so to a large extent, you're going to be on your own just fiddling with things until you find something that works.
