xCurrent Monitoring of Solar Panels - Multiple Strings
Solar PV String Level Monitoring. Up to 24 strings of panels are individually measured and supply energy and performance data.
In the drop-down menu, the number of hall-effect sensors is available in group of 4 , that means each group can measure 4 independent photovoltaic strings. The system is scalable to up to 24 solar panel groups.
In medium to large scale solar photovoltaic installation, the measurement of power generation down to string level is paramount.
Knowing how each string performs, it will help the solar park investors to optimise the performance and eliminate downtime. If a series of solar panels is not working as it is expected, the data of the digital monitoring system will be analysed before taking action to solve the problem.
The PV-Watch is made of a PLC controller and high accuracy current sensors. The Hall Sensors are available in a module with 4 entries and expand to up to 24 PV-Strings.
The maximum number of hall sensors is 24pcs which means 6 modules of 4 entries.
COMPATIBLE VOLTAGE AND CURRENT
The controller is compatible with PV string voltages up to 1500VDC. There are 3 options for current sensors at 20A, 30A and 40A.
The combination of multiple strings into one hall sensor is possible by selecting a high-current transformer.
Example.
PV String 1 : 10A, PV String 2: 10A, combined in parallel giving 20A. The output is fed through one current sensor measuring the power of two strings.
For better optimisation, individual strings should pass current through each sensor.
