Hi All, Am trying to charge a battery from solar panel array and for that am using mosfet irf 150. Driving it low side. i.e, load is conected to drain and source is conected to ground and am using a diode between battery (load) and solar panel Array. Now microcontroler will monitor the voltage of both solar panel array and battery (which is being charged) and will adjust the voltage level best for charging the battery by varying gate voltage of irf 150. My question is if i narrrow the gate of irf 150 the voltage at battery terminal will drop but if the ampares will remain the same or they will fall or not
