Hi I have a redarc bcdc1240 charger with solar input, the redarc is a 24v input, which is charging a 12v Lithium battery, the current through the shunt only shows about 16 to 20 amps where as a current clamp shows 40 amps current, is the smart shunt, is there a setting I can change to allow for current input
No, the smart shunt should be accurate - the only setting possible is for zero current error.
If your clamp shows a different reading, is there an alternate path around the shunt (stray / incorrect grounding is common)?
This is basically my set-up, except its a smart shunt,
Your drawing is wrong. The chassis ground on each battery by passes the shunt.
