2.4 Power Supply Setup
Depending on the installation type, there are various ways to power the LeNETmobile.
•
For remote sites and long term monitoring, a PV kit (solar panel and battery) is recommended.
•
For cost-conscious installations, a replaceable industrial alkaline battery pack can be used.
•
For indoor or energy metering systems, a mains power supply is suitable.
Note:
The power supply positive wire connects to the LeNETmobile
PWR+
terminal, and the negative
wire connects to the
GND
terminal.
2.4.1 PV Kit Power Supply
The LeNETmobile can be powered from a 6V or 12V rechargeable battery and PV panel kit for reliable
long-term operation on remote sites.
•
The solar panel works best when it receives full sunlight, so mount it away from fences,
buildings, trees or other obstructions that may cast shadows on it.
•
The panel should be mounted facing south in the Northern Hemisphere, and facing north in the
Southern Hemisphere for maximum sun exposure. The vertical angle depends on latitude (usually
about 30º angle)
•
Mount the enclosure and panel on the mast, mount pole or wall with appropriate brackets.
•
Connect the PV kit output cable to the LeNETmobile power terminals: “+” (red or white wire) to
LeNETmobile “PWR +” and “–” (black wire) to LeNETmobile GND.
2.4.2 Mains Power Supply
The LeNETmobile can be powered from any mains power supply that can provide up to 2 Amps at
typically 9 Volts. This is typically a plug-pack or DIN-rail switching supply. Connect the supply output
directly to the LeNETmobile power terminals, and avoid use of excessively long cables.
2.4.3 Battery Power Supply
The LeNETmobile can be powered from an alkaline battery pack consisting of 6 D-cells. Only use good
quality industrial cells for maximum life. These will typically last around 3 months. Always use
LeSENSE to monitor the battery voltage, and/or set up a LeSENSE alert to warn of low battery. The alert
trigger point should be set at 7.5V. See the LeSENSE user guide for details of how to configure alerts.
