Growatt MID 50K-HU Inverter

The Growatt MID 50K-HU Inverter features advanced maximum power point tracking (MPPT) technology that maximizes the energy captured from the solar panels continuously. The system features extremely intelligent MPPT response time and adapts to the constantly changing environment to keep your energy generation at an optimal level throughout the day. The inverter's tracking does not delay in performance even during partial shading or cloud cover while handling the optimum operation at all times. You always receive maximum return from your energy investment.

The MID 50K-HU incorporates enhanced current handling capabilities to ensure the inverter integrates with today's highly efficient solar modules - including state-of-the-art bifacial solar panels that are designed to utilize reflected light from the surface below them. The design of the unit has been far superior to others and does away with power reduction even under cloudy conditions that some systems perform in, known as "bottlenecking."

The MID 50K-HU's comprehensive array of monitoring and management tools gives you exceptional oversight. The inverter offers integrated smart connectivity that provides real data regarding performance, energy delivery and operational status. User-friendly and remote access capabilities allow users to take stock of energy assets at any time from virtually any location.

The entire suite of monitoring and management tools includes proactive diagnostic capabilities that continuously monitor and evaluate the health and performance indicators of components. This smart monitoring provides alerts of potential issues ahead of time, allowing for preventive maintenance before the performance or energy output is impacted by an issue. The platform also provides data analytics which allows for the transformation of raw operational data into actionable intelligence that may be advantageous for maximizing the system performance during the intended lifespan.

Safety is at the center of the MID 50K-HU's design philosophy. The inverter features multiple layers of protection for electrical faults, environmental issues, and operational issues. Advanced safety features protect equipment and systems that are connected to the inverter from unexpected events while ensuring stable operation in a variety of operating conditions.
The unit has enhanced safety protections with a focus on electrical safety, including advanced arc fault detection that automatically detects potential hazards as well as corrective action. In addition, the inverter features comprehensive surge protection and isolation safeguards, creating a secure energy design against electrical disturbances.

Designed for seamless grid connection, the MID 50K-HU has advanced grid management capabilities for maintaining power quality while operating within international grid certification protocols. Advanced electronic components within the inverter provide a smooth transition to utility power with any grid requirements for voltage and frequency regulation.

The system offers smart grid support functions for a future-ready application, providing flexibility as the energy infrastructure evolves. These functions will allow the MID 50K-HU to be a more dynamic forward-thinking solution that can adapt to changing energy needs, standards, and grid requirements.

 Technical Implementation: The inverter is capable of operating with a DC/AC ratio of 2:1, which means it can control up to 100 kWp of solar modules while only providing 50 kW AC. The inverter possesses an MPPT range (usually in the vicinity of 160–1000V), as well as multiple MPPT trackers for the purposes of energy optimization.

 Application Benefits: Offers greater system flexibility under circumstances of partial shading, misaligned module orientation, or degradation of modules over time. Especially applicable at high latitudes or on commercial rooftops where modules may be differently orientated. The ideal DC/AC ratio should be designed in consideration of local irradiance, expected degradation, and grid limit.

 ​​Hardware Design​​: The inverter offers ​​either 3 or 4 independent MPPT (Maximum Power Point Tracking) inputs​​, with each MPPT capable of managing ​​multiple strings of PV modules​​.

 Operational Advantages​​: Enables ​​optimized energy production​​ when connecting ​​PV arrays with different orientations, tilts, or partial shading conditions​​. For example, it can efficiently manage ​​a primary south-facing array alongside secondary east/west-facing panels​​, reducing power loss due to module mismatch.

 ​​Functional Overview:​​ The inverter has built-in support for backup power applications.

 ​​Operational Mode:​​ In the event of a grid outage, the inverter will switch to off-grid mode (assuming it has batteries and is properly set-up) to provide power to critical loads. However, the ability to function off-grid depends on the battery storage and overall system design - the inverter itself does not provide stand-alone or off-grid service without storage functionality.
