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.
- High Total Efficiency – High reliability and efficiency with low auxiliary consumption for rapid return on investment. MPP efficiency >99.9%; Maximum efficiency >97.5%
- PV compatibility – Su-Kam Grid Tie Inverter is designed to take advantage of solar modules configured as high voltage PV string arrays – with an input voltage Maximum Power Point Range of 150 to 550 Vdc.
- Maximum Power Point Tracking (MPPT) – Su-Kam Grid Tie Inverters use Maximum Power Point Technology (MPPT) to harvest the maximum amount of energy from the solar array. Provide single and double MPP trackers for different application demands.
- Expandable – Multiple grid tie inverters may be networked together for increased net metering capacity or future system growth. Parallel up to 50 units via RS485 port.
