Ok 2nd try. Shorter version. 100w 18v panel to 75/15 smart with bluetooth to 195ah deep cell. Full sun -at start voltage reading from panel 17.6v all good. To battery from controller 14.4v in bulk mode all good. Problem readout no amps from panel to controller and no amps from controller to battery. Plus despite battery not being full controller goes from bulk to absorbtion to trickle charge mode in about 20 seconds and stays there all while there are still zero amp readings. Everything was properly installed. Changed the fuse. No difference. Any ideas
