Warranty: 5 years
Fox ESS T4-G3 Three-Phase Inverter
The Fox ESS T4-G3 is a three-phase solar inverter with a rated power of 4 kW, designed primarily for residential and small commercial systems. Its two independent MPPT trackers allow for flexible system configuration, such as in the case of solar arrays with different orientations or tilt angles.
The inverter has a maximum efficiency of 98.6% and an MPPT efficiency of 99.8%. Thanks to its low starting voltage of 140 V and its wide MPPT voltage range of 140–1,000 V, it is capable of efficient energy production even under varying light conditions.
The fanless cooling system, which operates using natural airflow, ensures quiet operation at less than 30 dB. Thanks to its IP65 rating, the device can be installed outdoors under appropriate conditions. The system’s operation can be monitored remotely via the FoxCloud V2.0 interface, a mobile app, or a web browser; this requires an optional Wi-Fi or 4G communication module.
