Solar generators are useful.
Products called "solar generators" are generally boxes equipped with solar charge controllers, batteries, inverters, and mains chargers. The energy stored by the battery is usually 12 volts direct current, the inverter can convert the direct current stored in the battery into the household power voltage (frequency is 50/60 Hz, voltage is 120/220/230/240 volt alternating current), the solar charge controller controls the multi-channel solar cell array to charge the battery and the battery to supply power to the solar inverter load, and the mains charger (interface) can obtain electricity from the mains or diesel gasoline generator to charge the battery.
You can charge the battery from the grid first, and then bring the solar generator to the suburbs to supply power to the load; or use the solar generator to supply AC and DC loads when the power is out at home. And if you are in an area with a lack of power grid or go out for a long time, you need to use solar panels to absorb solar energy and convert it into electrical energy to store in the battery.
The above are some basic knowledge about solar generators. For more information, please contact Xindun.
