Charging a 24V Battery with 20V Solar Panel & MPPT Charge Controller
In part one of our series, we demonstrated how to charge a 24V Battery with 20V Solar Panel & PWM Charge Controller. Today, we're going to be doing the same demo, but using an MPPT charge controller instead.
In our demo below, we're using the Midnight Kid MPPT charge controller. For solar panels, we've got a Canadian Solar 280 watt panel that's 24V and a SolarWorld 75 watt, 20V panel.
Let's see what happens when our Solar Queen attempts to charge a 24V battery with a 20V solar panel and MPPT charge controller on a hot, summer day. And see how that compares to doing the same, using a 24V solar panel.
