i am having a bit of a problem with my Balmar MC-614 alternator and my LiFeP04 batteries.
The symptom is that when the engine is first turned on the alternator ramps up to 100% SOC on the batteries.
Then the SOC starts dropping and I do not know how far it will drop, I get worried and fire up the generator. One timeI let it continue to go down to 77% before turning on the generator.
This phenomenon does not happen when on AC power and the Victron multiplus is operating.
The MC-614 is set to the default LiFeP04 settings
Attached are the default MC-614 settings, and a graph showing my SOC. You can see where I started the engines on the left, we got a good initial charge, and then the SOC started going down.
Also is a graph showing my currents and voltages on the system.
Any clue what the fix is?
The only thing i can see s that the float voltage is set a bit lower than the victron gear at 13.4 volts vs the victron I am setting at 13.5
It's not a voltage sensing issue as the balmar is showing the same voltage as the Victron.
There is something called "calculated float voltage" that seems to come into play using the Balmar, this seems to be to be odd.
What have others done to resolve this using the Balmar regulators?
