I am using a MPPT 75/15 charge controller between a PV cell and a lead-acid battery. The battery voltages at which the load disconnects and reconnects is very important to the application. I am familiar with these voltages based on the data-pin jumper position, but what about the behavior when their is no jumper.
Furthermore, I need to monitor serial data over the port, will this change the load disconnect behavior at all?
Is there any way to set the load disconnect/reconnect voltages?
Any help is much appreciated. Thank you.
