Inverter – FoxESS – T17-G3-GD470
Product details
T(G3)
T(G3) is a series of three-phase inverters rated from 3–25 kW, designed for residential and small commercial installations. Low start-up voltage, a wide voltage range and a maximum efficiency of 98.6% support efficient system operation. The series enables remote monitoring and expansion with FoxESS storage systems using an additional FoxESS device.
Key benefits of T(G3)
- Power 3–25 kW depending on the model, during three-phase operation.
- Maximum efficiency 98.6% and low start-up voltage and a wide voltage range.
- IP65 protection rating and the option of outdoor installation.
- Real-time monitoring via a smartphone app or web portal.
- Expandable with FoxESS energy storage — requires an additional FoxESS device.
Who is this a good choice for?
T(G3) is a choice for households with three-phase systems and businesses using small commercial installations. The power range allows a model to be matched to the installation, while remote monitoring provides an ongoing view of its performance. The option to expand with a FoxESS storage system meets the needs of users planning to add energy storage later, taking into account the additional FoxESS device required.
