NEW: MpicoSys revolutionizes solar power charge management – enabling low power year round 24/7 operation. Meet MpicoSys Low power Solar Charge Controller, optimized for winter.

Why develop a low power solar charge controller?
One of the customers in the North of Europe experienced – despite using low power products from MpicoSys – a need for battery changes in winter. Research showed that next to little sunlight the battery was drained due to the power used by the charge controller. The controller appeared to use more power than generated by the PV – standard power consumption appeared to be 10mA – needed day and night, 24/7! Next to the fact that the charger used was optimized for summer. The efficiency of a standard charge controller is 80-90% in bright sunlight, 10-30% in low light conditions.
Hence the need for a low power solar charger, optimized for winter for digital (remote) bus stops, or any other passenger information..
