The solar generator is more than a battery and therefore cannot be referred to as a simply a ‘battery’ because in a way, it generates energy. When solar power comes in from the solar panels, it is stored in the battery contained within the generator in the form of DC current. To make this energy usable, the built-in inverter converts it into AC and passes it out through the generator’s output system and into the devices that need to be powered. The solar generator as a unit is made up of the battery, battery charger, and inverter, and when you connect the solar panel, it becomes a constituent component too and, therefore, isn’t just a battery. So yes, the solar generator, through the inverter, generates the AC current needed to power devices.
