Luminous NXI 320 Solar Grid Tie that can feed power from solar panels directly to grid. They are designed to quickly disconnect from the grid if the utility grid goes down (anti-islanding). More than 97% efficiency: The transformer-less design makes Luminous GTI highly efficient to deliver maximum Solar Power. Dual MPPT/Quad MPPT: Inbuilt MPPT charge controller extracts upto 30% more power from the panels. Dual/Quad MPPTs provides you the flexibility of connecting multiple arrays, which helps minimize the impact of shading, increases efficiency, resulting in more solar generation. IP65 Protection: Luminous GTI is IP 65 certified product hence it is suitable for outdoor Installation also. It can work in extreme weather conditions such as dust, heavy rains, excessive heat or extreme cold. Anti-Islanding protection: This does not send electricity to grid if Grid has failed, thereby ensures complete safety of line workers. MNRE & IEC compliance: GTI complies with all the National & International standards for safety and efficiency and reliability, such as IEC – 61683, IEC – 60068, IEC – 61000, IEC – 61727, IEC – 62116
