4, The portable solar panel can only convert out DC power, no AC output. And the portable solar panel can be only used under direct sunlight, no working in rainy and cloudy condition. So that a battery can be used together with the portable solar panel to store power. A solar controller can be there to protect the charging for the battery. Then an inverter can convert the power in the battery to AC output.
