Solar dependence on the environment affects the change in output values in hybrid plant systems, resulting in easy damage to both domestic and industrial appliances or in battery storage systems, so a mechanism is needed to stabilize the output voltage supplied to the battery or load.
Results from the testing of this device indicate that the buck-boost converter is able to stabilize output output from solar panels with a 14.4 volt set of points.
