Hibridno napajanje telekomunikacione i merne opreme daljinskih mernih stanica u sistemima zaštite od poplava

The paper will present the implementation of a hybrid power supply for telecommunication and corresponding measuring equipment of remote measuring stations, which are an integral part of the flood protection system. Solar power is the primary energy source during the day, while in night conditions it is actually used as a distribution network (which also supplies street lighting). The power system is implemented with two controlled MPPT chargers (mains and solar), 12V / 110Ah battery bank and associated monitoring system. The paper will present key experimental results obtained during the release of a concrete realized measuring station and associated telecommunication equipment, on the Ub River, Ub Municipality.
