Su-Kam Grid Tie Solar Inverter is designed to convert solar electric (photovoltaic) power into utility-grade electricity that can be utilized by the home or sold to the local power company. Advanced state of the art electronics embedded inside the inverter ensures that maximum PV power is converted to AC and delivered to the Utility grid. These inverters are configured to feed into the LT(low voltage) utility network and have inbuilt safety anti islanding feature to ensure that the inverter switches off when grid absent. In order to operate, the Solar Grid Tie Inverter must have grid power available and connected. A wide input voltage range gives the flexibility to the designer to use a large range of PV modules.
 
Working Principle
Installing the Grid Tie Solar Inverter consists mounting it to the wall and connecting the DC input to a PV array and the AC output to the utility.
 
Features
