Given that power consumption requirements of a met station, depends on the sensor configuration, communication mode and setup of the met station, a single power supply solution for all met stations is not possible. We do however recommend using a flotation (back-up) sealed lead-acid battery (12VDC). This type of battery has no maintenance and can be transported in any orientation.
If you are using an internet / GSM connection to your data logger, we recommend using a 40Ah battery.
The EOL Zenith data logger does not have an internal battery. External power supply is therefore essential for proper operation.
The Orbit 360 data logger does have an internal backup battery, however this is only meant for emergency backup and an external power supply is therefore also necessary for proper operation.
