Can someone please help. I've got brain jam and the more I look into the less clear it seems.
I have 2 of these. One for the main power and one for the solar.
RSB-200-100
Manufacturer
Riedon
Description
RES CHAS MNT 500 UOHM .25% 20W
Detailed Description
500 µOhms ±0.25% 20W Metal Element Chassis Mount Resistor
What value should I enter on the SBMS0 for the shunt values?
Or can someone let me know how you calculate what it should be?

On Page 7 of the SBMSOv03d PDF User Manual describes how to calculate shunt values for calibration
Unless i am mistaken

I am taking a stab at it being .5000

Great thats what I got. Have just been questioning myself.
.1v / 200a
Was wondering if you use the rated current (200) or the operating current from the data sheet (133) ?
As you see I'm probably over thinking things.

Your answer is already in the spec sheet you provided 500 µOhms = 0.5000mOhm
And if you only had the rated current and the voltage output at that rated current then:
0.1V / 200A = 0.0005Ohm = 0.5000mOhm
