In this case with a Rosie and a Classic you probably want the Classic doing SOC as boB mentioned the device has to go to float on occasion to trigger a calibration so if Rosies charger is not in use then you will always see CAL unless the classic is pushing battery voltage higher than the Rosies voltage for longer than Rosies absorb time. So for example:

Classic Absorb is 58.0 set Rosie to 57.5
Classic Absorb time is 2:00 set Rosie to 1:30

This way Rosie will still transition to float internally

The wbjr is connected and functional in the Rosie.

I'll diddle with the setting of the Rosie. Right now, settings mirror the Classic as far as battery charging goes.

System one: 7kWp w/ Trina 250 W panels @90 Vdc. Classic 150 to 16-6 V U.S batteries. Trace 5548 sine wave inverter.
System two: 6kWp grid tie with solaredge inverter.
System three: Midnite Brat, two 120 W Astropower modules, 100 Ah battery. Runs the LED streetlight in the back yard.

Checked the settings and they were set at the following:

Classic absorb 59.9V Roise 58.7
Classic absorb time 3:40  Rosie 3:00 (both in hrs)

Classic float 54.5  Rosie 53.6

We're getting plenty of sun, and I've been in float every say since end of February.

Rosie still in 'cal'
