Hanut India : Solar PV string monitoring system
 

       Hanut India solar PV junction box with string monitoring


Having invested huge amount of capital in their solar PV plants, the plant operators want to get the maximum output from their photovoltaic power plants. 

The solar photovoltaic plant operators want to know the reason behind any / every fall in the PV plants output - whether the fall is due to some known cause [cloudy weather, planned maintenance,... etc.] or the fall is due to a fault in the plant that needs to be rectified.

And, in case of fault, they want to know the exact location of the fault.

A solar PV plant typically has hundreds / thousands of PV modules spread over a large area. Using conventional means finding answers to both these questions is very difficult and/or time consuming.

The string monitoring and diagnostics system offered by Hanut India is a smart solution to above mentioned problems.

The  string monitoring and diagnostics system provides clear and up to the minute information about the entire generating section of the solar plant. Alarms are displayed locally and on the central monitoring server showing the exact PV module string / array junction box with fault for immediate action by the plant operators.

The  string monitoring and diagnostics system offered by Hanut India is affordable and simple to install.

Please see the block diagram below to have an understanding of the string monitoring system.

Key Features of Hanut India's PV string monitoring system:

provides detailed information about the power generated by each string of PV modules.

provides information about out-of-order or disturbed strings.

Upon occurrence of a fault in the power plant the system gives clear and visible reference points of the place, where the fault is registered and the nature of the fault. Such information is accompanied by a visual alarm in the concerned field array junction box and the central monitoring server.

monitors the status of the fuses of each string

each measuring module does a self-check up on power ON.

the system installation is easy and quick as the measuring module comes pre installed in the array junction box provided by Hanut India. Hanut India can customize the array junction box as per plant operator's requirements.

The string monitoring module needs NO additional cabling for power supply and data transmission as it takes power from the PV module strings and transmits data to the central server wirelessly. Absence of power and data transmission wires is a very BIG advantage.

User friendly software is provided for monitoring the performance of all the strings from a central location.
