Hey Will, I absolutely love your channel - it has helped me a tremendous amount over this past year. Your way of explaining everything is awesome.
I have a completely off-grid system, it currently has:
one Kilovault 7.5KW battery,
one outback front end (Specifically, the Outback FlexPower One - 48V FP1 FXR3048A-01).
12 x 380W Canadian solar (total approx 4kw) panels connected in 4 strings.
All combined in a Midnite solar combiner box.
I have no complaints about the Kilovault products. Mine has been working well for about 5 months so far and handles load very well.
Here is my issue:
I am having a hard time configuring my Outback charge controller/Inverter/FX to get the SOC of the battery to be 100% at the same time that the Outback system shows it is at 100%.
More often than not, I get to a point where the outback system says the SOC is 100% - but the battery's OpenHAB app shows it to be 75% or whatever.
Do you have any experience with Outback hardware/software configuration, and can you assist with the configuration such that outback works better with these kinds of batteries. Below is my current configuration.
I'm an engineer by trade (Software), but have a lot of electronics background and have experience setting up other solar systems, so I think I understand the basics and terminology, but am always happy to learn!!
To be specifc, this is an OFF GRID system. Here are my outback settings:
