The CloudRain Valve is designed to be powered solely by the solar panel. An internal battery provides enough reserve, even if no sun shines for a few weeks.

Should it be necessary under certain circumstances, the CloudRain Valve can also be charged via an external power supply. On the bottom of the valve is the charging port.

Please contact us if necessary, we can recommend you a suitable power supply.

Below is the technical information for the charging port.
