8.2.2 FlexPower with Integrated Battery
Some FlexPower devices operate using a battery integrated into the housing.
These devices powered by integrated batteries:
•
Operate only from the battery and cannot use an external power supply, and
•
Are limited in the available I/O because of the limited connectivity.

Solar Supply
Banner’s FlexPower Solar Supply Assembly can supply power to two radio devices, including a FlexPower Node, a
FlexPower Gateway, or a data radio.
When used with a FlexPower Node and sensors, the FlexPower Solar
Assembly supplies enough power to run most sensors at higher
sample and report rates than a single battery can reasonably
support.
The solar panel recharges the battery pack that powers the devices.
