Title
Powering a Senquip Device with Solar
POWERING A SENQUIP DEVICE WITH SOLAR
1. Introduction
Senquip ORB and QUAD devices can be powered with DC from 10V to 75V, using AA batteries (Senquip ORB only), or
using solar. In most solar systems an external regulator and battery are not needed, with the internal LiPo backup
battery powering the Senquip device and attached sensors during the night. External sensors, and device settings
impact solar system performance and will be discussed along with the choice of solar panel.
This application note focusses on solar; for further information on general low power applications, see application
note APN0004.

2. Impact of Device Operation on Power
Senquip devices can be configured to take periodic measurements, process, transmit, and then to return to sleep. A
simplified flowchart of Senquip device operation is shown in Figure 2. The aim of any low power application is to
minimise the time that the device spends taking measurements, processing, and especially transmitting, and to
maximise the time the device remains in sleep.
