Using Solar Panels Without a Battery. While using a solar panel controller without a battery is not the typical setup, there are some alternative options for utilizing solar power without a battery: 1. DC-to-DC Converter. One way to use a solar panel without a battery is to connect a DC-to-DC converter directly to the panel.
If the controller VOC is 100 volts, and 3 solar panels with a VOC of 22 volts each are connected in a series, the controller can handle it because the total is 66 volts. In these examples we will be using an MPPT charge controller because it provides better performance with high powered solar panels compared to PWM.
