This SP 002 USB Solar Panel allows indefinite operation of the Noise Sentry RT and Noise Sentry RT-W instruments, even in prolonged overcast conditions. Its output voltage is always safe for these instruments.
NOTE: In order to work properly with USB output solar panels, including the SP 002, the Noise Sentry RT needs at least firmware revision 1.5. The Noise Sentry RT-W needs at least firmware revision 1.4. If unsure, install the latest version of the Noise Sentry RT Manager, or Noise Sentry RTW Manager application, depending on the instrument.
For customers who wish to use untested USB output solar panels with our instruments, we strongly recommend the use of our USB Charge Conditioner.
