I've seen several questions on here related to this question (This, this, and this), but I'm still confused about what is possible. Is there a way to configure the load output terminals to turn on only when the PV voltage reaches a certain threshold, or can you only configure this based on battery voltage? My goal is to turn on a small pump connected to the load output terminals only when the PV voltage reaches 25v, and then disconnect that load when it drops below that threshold. I have a Smartsolar 100|20 mppt charge controller. Thank you!
