Description
The FoxESS R Series (G2) range is specifically aimed at 3-phase commercial and industrial installations, offering “unrivalled performance and versatility for increased yield potential and longer generation windows”. The R125-G2 model stands as a high-capacity powerhouse within this series.
High Yield & Industrial Performance
The R125-G2 is engineered to maximize energy harvest from dawn until dusk. With a low start-up voltage of 250V and a wide MPPT operating voltage range (200V – 1000V), this inverter captures energy efficiently even in low-light conditions. Its 10 independent MPP trackers provide exceptional flexibility for massive commercial designs, ensuring each string performs at its peak potential. The unit is also compatible with bifacial modules and features a 40A max input current per MPPT to support modern high-power PV panels.
Smart Maintenance & Monitoring
Stay in control of your energy fleet “anytime, anywhere.” The R125-G2 supports accurate PV string current monitoring for precise real-time diagnostics and string performance analysis. It also includes a PID Recovery function, which improves panel efficiency over the lifetime of the system by preventing and reversing degradation with auto-detection. System performance can be monitored via the LED display or through Wi-Fi+APP connectivity.
Uncompromising Safety & Reliability
Safety is a standard priority for FoxESS. The R125-G2 includes an integrated Arc Fault Circuit Interrupter (AFCI) to provide safe and reliable protection against arcs with an accurate and fast response. It also features Type II Surge Protective Devices (SPD) on both the DC and AC sides, alongside insulation and residual current monitoring. Encased in an IP66-rated housing with C5 anti-corrosion protection, it is “refined, powerful, and flexible,” engineered to last in extreme environments with temperatures ranging from -30°C to 60°C.
