Isolation systems (independent) are autonomous systems typically used to provide power to users who are difficult to connect to (such as areas with inconvenient transportation) or users with extremely low energy consumption, thereby making the connection to the national power grid inconvenient.

The characteristic of an isolated system is that it needs to meet all the energy needs of users, which have the following basic elements:

1. Photovoltaic modules

2. Charging controller

3. Storage system (battery)

4. Inverter (converts direct current to alternating current)

In the absence of a power grid or difficulty in reaching it, these systems are cost-effective. In the event of a power failure, an independent system can also ensure the continuity of power supply, especially since its integrated storage system can be used when the photovoltaic panels are not working (such as at night).
