GPRS DTU for distributed off-grid solar power station monitoring system
System survey:

             The distributed off-grid solar power station monitoring system is aim at solar street lamp or distributed off-grid power station long-distance real time on-line monitoring of R&D.Ii will through solar cell array voltage and electricity、load working current and ambient temperature and  humidity,will real time warning、alarm、generating statistics,and it have controllable function for hardwired on-off,accuracy and effective control segment hardwired on-off,will protect solar power supply system.The system can on-line monitoring solar system accumulator capacity and socking out time,provide reliable basis for site user grasp effective solar power supply system running status and fault protection, to avoid failure of a solar power supply system,cause the damage by load,maintenance work effective is improve,reduce the maintenance cost and staff cost. The application network diagram of distributed off-grid solar power station monitoring system as follow.

Customer design 《The distributed off-grid solar power station monitoring system》simulation demonstration

             Customer evaluation: As the Internet of things application in the field of new energy,through use four-faith communication GPRS terminal product can realize the remote transmission of date,can be realized multiple distributed site monitoring network management.At present use four-faith F2103 terminal product can realized long-distance upper computer software data interaction,use four-faith wireless communication terminal F1103 ( SMS MODEM ) can realized SMS warning function,use F2003 IP MODEM can realized data forwarding functions of mobile phone, since 2011, the test feedback is good."
