The solar modules convert solar energy into electrical energy. This electrical direct current is then converted in the inverter into the 230V usual in the household.
Furthermore, this inverter provides the electrical power for self-consumption. The electrical energy that is produced more than is currently used is used to charge the batteries.
The advantages of this type of system are that even where I could not use normal household appliances with 230V before, they can now be used. This type of system is absolutely self-sufficient.
The example system is intended for a mobile home or a garden with small consumption. Of course, the size can vary depending on your needs.
