Hi Pete, I've had solar panels on our Landfall 35 for a year now (2 x 100w HQST semi flexible in parallel 12v, Renogy Commander 40A controller, MT-50 remote monitor). The controller flashes a light when charging batteries and any indication of a charging problem (battery issues, bad connection, etc) gets a flashing red light. The remote monitor also shows charging volts and amps and if there's a positive flow to the batteries.
My MT-50 monitor recently had display failure but the system was still operational. The monitor can help you set charging parameters as well. If you are hooking up the panels directly to the battery with no controller, you're asking for serious overcharging from a 100w panel in direct sunlight. If you have a controller, check the manual for indicator lights or readouts from the controller (or check with a multimeter). Mine typically put out 16-18v when in direct sunlight.

Bought from Amazon, this panel [KingSolar, probably Chinese] was purchased and installed in August, 2019. I checked the MC connectors, they were OK. Can anyone share their experiences with trouble-shooting solar panel issues? Thanks, Pete W. Siren Song '91 C&C 30-2 Deltaville, VA.
