SKU: T20-G3-GD470
Product details
T(G3)
T(G3) is a series of three-phase inverters designed for residential and small commercial installations, covering power ratings of 3–25 kW. Low startup voltage, a wide voltage range, and a maximum efficiency of 98.6% are its key features. A remote monitoring platform enables real-time tracking of system performance.
Key benefits of T(G3)
- Power range 3–25 kW depending on the model, for three-phase installations.
- Maximum efficiency 98.6% and low start-up voltage and a wide voltage range.
- IP65 protection rating and the option of outdoor installation.
- Remote real-time monitoring via a smartphone app or web portal.
- Expandable with FoxESS storage systems — requires an additional FoxESS device.
Who is this a good choice for?
The T(G3) series is designed for households with three-phase systems and businesses using small commercial installations. The 3–25 kW power range allows users to select a model suited to their installation, while remote monitoring makes it easier for owners to track its performance. The option to add FoxESS energy storage, using an additional FoxESS device, meets the needs of users planning to expand their system.
