Photovoltaic panel automated Description and Specifications for Lab Tenders
Photovoltaic panel automated.
The suggested system includes two photovoltaic panels, an
inverter connected to a load controller and a solar storage
battery. It enables to evaluate the devices for transformation,
transport and storage of power. The telemeasurement and
telecontrol system present on the control and supervision panel,
connected to a PC facilitates monitoring the main electrical
operation parameters: voltage, current, power factor, frequency
and consumption. It enables to control two programmable
outputs and a unit for the PC conversion: RS485/RS232.
