Grid Tie Inverter | 15KW | 380V/400V | Max. PV Power: 22500W | IP65
GRANKIA TP15KTL best 3 phase photovoltaic 15kw on grid tie inverter is ideal for commercial and industrial applications.
The 3 phase 15kw on grid tie inverter boasts a remarkable efficiency rating of up to 98.4%, ensuring maximum energy conversion from solar panels to usable electricity. This high efficiency translates to increased energy savings and a quicker return on investment.
This on grid tie inverter supports a wide input voltage range, allowing it to work efficiently with various solar panel configurations. This flexibility ensures optimal performance regardless of the specific solar array setup.

Three-Phase Output
With a three-phase output configuration, the 15KW on grid tie inverter effectively balances load distribution and enhances system stability. This feature is particularly beneficial for larger commercial systems requiring robust performance.
Grid Compatibility
The inverter meets global safety and grid connection standards, ensuring seamless integration with utility networks. It supports multiple protection functions such as anti-islanding, surge protection, and fault detection for enhanced safety.
Dual MPPT Channels
With dual Maximum Power Point Tracking (MPPT) channels, the TP15KTL can independently optimize the performance of two separate solar panel strings. This feature is particularly beneficial for installations with panels facing different directions or experiencing varying shading conditions.
Low Noise Operation
The inverter operates quietly, making it suitable for residential and commercial environments where noise levels are a concern. Its fanless design minimizes operational noise while maintaining effective cooling.
Integrated Anti-Islanding Protection
The grid tie solar inverter includes built-in anti-islanding protection, which ensures that the inverter automatically disconnects from the grid during power outages. This feature enhances safety for both the inverter and utility workers.
