DIY SolarFirst we will see how to set up your solar power system to start and run a refrigerator or freezer on solar power using batteries. Next we will run appliances by connecting the solar panel directly to the inverter to run a few appliances. And finally we will see what is needed to start the refrigerator whithout using batteries. Batteries in a solar power setup provide many advantages. They provide both short term and long term energy storage. But for very high instentaneous power you need either a large battery or you can combine supercapacitors with a small battery to get the same results. Supercapacitors have the advantage of providing a burst of power for a very short duration which is needed when starting an induction load such as a refrigerator or freezer.
