Product details
Commercial Inverters WIT 50-100kW H/HU
WIT 50-100kW H/HU Commercial Inverters represent the state-of-the-art in energy management for commercial and industrial applications, offering a unique combination of superior performance, flexibility and reliability. Designed to meet the most demanding requirements, these inverters are the ideal solution for any business looking to maximise energy efficiency, ensure operational continuity and minimise long-term costs.
Why choose WIT 50-100kW H/HU inverters?
Integrated UPS Functionality and Operational Resilience
These inverters are equipped with an integrated UPS, guaranteeing continuity of power supply even in the event of grid outages. The black start function enables a rapid resumption of post-incident activities, minimising downtime and protecting your critical business operations. This saves you money by avoiding lost production downtime, and you don't miss a minute of business workflow.
Compatibility with Uneven Tasks
Comprehensive support for non-uniform loads ensures efficient management of connected equipment, even in phase load imbalance situations. This capability enables stable operation of all devices, preventing overload and optimising power distribution efficiently.
Overload Capability and Increased Reliability
With 110% continuous overload capacity, WIT inverters can cope with temporary increases in power demand while maintaining system stability and functionality. This feature is essential to respond to fluctuations in power demand in a dynamic operating environment, ensuring that production does not stop even at peak times.
Advanced Surge Protection
The integration of SPD II protection on both DC and AC sides provides robust surge protection, ensuring system integrity and extending the life of connected equipment. This level of protection is crucial to prevent damage caused by surge events in the network, helping to save resources and avoid unexpected costs.
Conversion Efficiency and Energy Optimisation
WIT inverters achieve a maximum efficiency of up to 98%, minimising energy losses in the conversion process and maximising the use of available resources. The multiple MPPT inputs allow optimised solar energy capture, giving you more energy available for consumption and reducing operational costs. This means direct savings on your energy bills and a positive impact on your business profitability.
Scalability and Systemic Adaptability
Designed to grow with your business, these inverters allow you to expand capacity up to 300 kW, seamlessly adapting to changing energy requirements. Compatibility with lithium and lead-acid batteries offers flexibility in energy storage solutions, allowing you to choose the option best suited to the specifics of your operations.
Remote Control and Monitoring
The Generator Remote Control (DG) feature allows you to monitor and manage your power system from anywhere, ensuring you have complete control over operational performance and stability. This functionality is essential for performance optimisation and efficient management of your energy infrastructure, saving you time and resources.

Technical Benefits and Advantages
Choosing WIT 50-100kW H/HU commercial inverters is a strategic decision for any installation requiring high performance energy solutions. With exceptional efficiency, high overload management capability and advanced surge protection, these inverters offer the reliability and flexibility needed to support the growth and operational efficiency of your business. In addition, these solutions help save financial resources and maintain a continuous, uninterrupted production flow.
