System voltage selection for solar system design

The voltage of conventional solar system is 12V \ 24 \ 48V

This is as follows:

12V system

System voltage 12V

Working voltage 17.5V

Solar plate: 12V solar plate in parallel

Battery: 12V battery in parallel

24V system

System voltage 24V

Working voltage 35.5v

Solar panel: 12V solar panel in series or 24V solar panel in parallel

Battery: 12V battery in series or 2V battery in series

48V system

System voltage 48V

Working voltage 71v

Solar panel: 24V solar panel in series

Battery: 12V battery in series or 2V battery in series

The above three specifications are common system voltage, and there are directly matched controllers, inverters and other equipment on the market.

In case of special voltage level requirements, such as 96V, 220V, etc., relevant supporting products need to be customized separately, with high cost and long after-sales service cycle.
