No PV current

I am metering 4.5 amps on the incoming PV wires. 40.21 volts on the input side of the PV lugs. This is a Smartsolar 100/30.


With the bluetooth monitor it sees the voltage but 0.0 amps.


I've simplified the system so that I can diagnose it. I have


one 12v Renogy 100ah lithium battery

Two 100watt renogy mono panels wired in series for 24v nominal

Smartsolar 100/30 charge controller.


When I turn it on or make changes it will move into bulk for 2 or 3 flashes and then to absorption.


Any help?

I solved it - stupid me. The one wire I was sure was okay was loose.
