With a rated AC output of 20kW and maximum DC input of 30kW, this inverter delivers industry-leading efficiency and durability for commercial and utility-scale applications . Its robust design and smart grid capabilities make it a cornerstone for high-yield renewable projects aiming to meet strict European energy standards and maximize return on investment.
Achieving a maximum efficiency of 98% and European efficiency of 97.5%, the inverter ensures minimal energy loss even under high-load conditions . Equipped with dual MPPT trackers and a wide voltage range (200-800V DC), it optimizes power harvest from variable wind speeds and solar irradiance, adapting to dynamic environmental conditions for consistent energy output .
Certified to EN 62109 and EN 50549 standards, the inverter meets rigorous European safety and grid synchronization requirements . It incorporates comprehensive protection mechanisms: anti-islanding, overcurrent, overvoltage, and short-circuit protection, ensuring safe operation for both the system and utility workers. With THDi < 3%, it maintains grid power quality even during peak energy feed-in .
Housed in an IP65-rated enclosure, the inverter withstands extreme temperatures (-35℃ to +60℃) and high humidity (0-95%), suitable for harsh outdoor installations . Integrated RS485 and Wi-Fi connectivity enables remote monitoring, performance analytics, and firmware updates via cloud platforms, allowing operators to optimize energy production and troubleshoot issues remotely.
Power manufacturing facilities, warehouses, and industrial parks with 20kW wind turbines or solar arrays, significantly reducing grid electricity dependence and carbon emissions.
Integrates into wind farms or wind-diesel hybrid systems, converting turbine output for grid feed-in while supporting grid stability through precise power regulation.
Supports energy-intensive operations such as greenhouse clusters, grain processing plants, and large irrigation systems, offsetting high electricity costs.
It weighs 48kg with dimensions 660x520x220mm, requiring sturdy wall mounting or dedicated equipment rooms for installation .
The standard warranty is 5 years, with options to extend to 10 years by registering the product and maintaining regular service records .
The inverter continuously synchronizes with grid frequency (50/60Hz) and adjusts output accordingly, ensuring compliance with utility regulations during frequency fluctuations.
Yes, it supports parallel operation for scaling systems beyond 20kW, with master-slave control to maintain balanced load distribution across inverters.
