LightCharge – Solar Auxiliary Battery Power System

The ICT LightCharge is a self-contained power system designed to extend runtime and assist powering of ICT instruments where bad weather and low light conditions known. The LightCharge is capable of powering a group of instruments, specifically up to maximum of 3x total of either SFM1 or PSY1 Loggers.

The ICT LightCharge is pre-programmed to a “Dusk to Dawn” configuration, when the Solar Panels are supplying enough voltage to the Solar Charge controller this will charge both of the external 12volt batteries up to 28.8volts. While the sun is shining the external power connection to the ICT logger is disconnected. As soon as the Sun sets and the panels cease to provide charging voltage, the 2x 12volt batteries are connected to the ICT logger allowing it to charge the internal battery. As soon as the sun rises in the morning the logger is again disconnected from the system. This configuration allows proper cycling of the internal SFM1 battery and lowers operation temperatures by charging the SFM1 in the cool of the night.

NOTE: DO NOT change the mode from “Dusk to Dawn”; this has been configured such that the ICT logger can discharge, as ICT SFM1 (2019) are not designed for 24/7 permanent external power. Please consult the warning supplied in each SFM1’s packaging.
