Solar range control system

The solar range control system uses a four channel dynamic boost algorithm to maximise the power generated from each individual solar panel. During the day the light tracks across the unit, illuminating and shading the panels. To capture energy efficiently from direct and indirect sunlight, the optimum power point of the panels is calculated in real time and the charge taken from the panels is adjusted, harvesting the maximum power from each panel.

The batteries are charged throughout the day from the energy harvested from the solar panels.  The solar range control system has battery management technology which mitigates full discharge by reducing the LED brightness till there is sufficient ambient light to charge. To maintain battery levels during transportation the battery can be disabled by briefly placing a magnet against the Solarpost, once installed the magnet is used again to activate ready for use. The advanced battery technology offers an exceptional temperature range & improved solar charging tolerance.

The Solarpost control system monitors the ambient light levels, anticipating the transition from day to night. The automatic transition allows for seasonal changes in light levels for any environment. As night falls, a 180 lumens- per-watt white LED illuminates. The brightness of the LED is regulated by a pulse-width-modulation driver circuit, the LED remains at a low light level until activated by the passive infrared (PIR) sensors. The PIR sensors have a detection range of up to 5m, on approach the LED brightens for 10 seconds, gently dimming to the low level.

The Solarpost control unit is fully sealed and uses IPX7 connectors.
