Connecting Power Directly via CH24 Power SupplyNote: The PSY1 is non-polarisedNote: Continuous connection of an external battery or constant powersupply (for days to months at a time) is not recommended as this can shortenthe life of the internal battery. ICT International recommend using a solarpanel directly connected (with no external battery backup in parallel)wherever possible; or a timer switch to turn off external power for 8-12hours daily to simulate a solar panel during the day and night.
