#solar #grownostr 2x 100w panels, 12 noon down in Texas, full sun, only putting out 10-20w according to the Bluetooth device. How to troubleshoot? Wrong angle? Short or something?

For Texas in October, you should be between 15-18° depending on where in the state you are.
Also if batteries are charged, the controller will throttle or stop production based on the battery requirements programmed.
