PV Solar String Monitoring System (PV Solar SMS) SOLAR SMS SLAVE 12IN25A

The PV Solar String Monitoring System is a new device developed to monitor currents and voltage at the string level inside a combiner box. This new device is able to monitor up to 32 strings and to measure up to 50A per string. It can be directly powered by the solar array while providing reliable information and data. In order to have a flexible design that can fit any customer's requirements, the Solar String Monitoring System (Solar SMS) has been developed as a modular system. It consists of: • The Master Module, which includes the power supply and communication infrastructure (RS-485) to coordinate data gathering from sensors. • The Slave Modules, which collect current data with the usage of hall effect sensors. These modules can mount 8 or 12 sensors each with 25A and 50A sensors respectively. Solar SMS Number of monitored channels: 12 inputs Max current/channel: 50 A
