The TRIO 27.6 inverter for commercial applications offers greater flexibility and control options to installers who want to build large systems with variable orientation.


 

The dual input section with independent MPPT tracking enables optimal energy harvesting even when strings are oriented in different directions. The TRIO features a fast and accurate MPPT algorithm for real-time maximum power point tracking and improved energy harvesting.


 

High efficiency at all output voltage levels:

• Flat efficiency curves ensure high efficiency at all output levels by ensuring consistent and stable performance across the entire input voltage and output power range. The wide input voltage range makes the inverter suitable for systems with smaller string sizes.
