2023 Tellaro 20L - How does one interpret the displays

[RonRM]

I was told there would be no math, that's certainly not the case!

I don't understand and can't reconcile this...please help?

The RV is NOT on shore power, the engine is not running - just solar.

The Balmar display shows +6.2 amps - I take that to mean that the batteries are getting a 6.2amp charge.

The BMPro shows

For the Solar controller
18.0 V - 7.3Amps coming in
14.0 V - 9.4Amps going out

How does that equate to +6.2amps being applied to the batteries?

I look at these numbers and think that I have a 9.4-7.3=2.1amp deficit.

Which would mean I should see a -2.1 on the Balmar display...not +6.2.

Hopefully, it's not just me loosing my mind.

You have 9.4 amps being supplied to the DC buss
6.2 of those amps are going into the battery to charge it.
The other 3.2 amps are going to DC loads on the DC buss.

The 18 VDC and 7.7 amps is the 131.4 watts the solar panel is applying to the solar controller.

The 14 VDC and 9.4 amps is what is coming out of the solar controller (131.6 watts but there are some reading margins so no, the solar controller is not creating energy).
