When it comes to choose the best inverter solution, you have to consider some specifications- DC/AC side protection, efficiency, real time remote monitoring and control and other advanced functionality such as SVG function, PID control and so on. EP-3.125MW-HA-UD, a utility-scale applicable inverter solution of Lailite, comply with all aforementioned specifications and was showcased in REI-2019. Eco-friendly and robust design for a 25 years lifespan makes it suitable for extremely humid or hot areas like Gujarat, Tamil Nadu, Maharashtra and Andhra Pradesh of India. It comes with anti-corrosion protection and IP65 for key components such as IGBT module, DC bus capacitor, SMPS for various drive and DSP control board etc.


Compact design and smart control algorithm of 3.125MW inverter give an ease of installation, controlling and monitoring. In means of 3-level topology and smart 2 phase redundant cooling method, the efficiency can be achieved up to 99%, and it can work without derating till 50-degree Celsius. It also features 1500V DC inputs, maximum DC/AC ratio of 1.5, flexible 6.25MW or 12.5MW block design and overload capacity of 115%. All of these characteristics allow this inverter to offer customers with high yields and easy O&M which, in returns, profit the customers with a large amount by optimum LCOE. One of indisputable features is night static var generator (SVG) functionality what helps plant owners utilize inverter efficiently before and even after sunset by injecting controllable reactive power to the grid. Additionally, Inverter also owns negative grounding technology for recovering module PID effect and an auxiliary power supply. Input and output side of the inverter is designed following IEC, EN and other standards so as to secure the highest level of safety for inverters and users.  It is a front maintenance and modular designed device which saves time and is convenient for inspecting and repairing while any fault occurs. To connect to the grid as per IEC and CEA requirements, respectively, it is also featured with anti-islanding, over/under voltage protection and LVRT capability for smooth operation.  It is obvious that this machine is equipped with everything what a plant owner would wish for.
