Description
The FoxESS U Series is designed to meet the rigorous demands of 3-phase commercial installations, offering “unrivalled performance and versatility for increased yield potential and longer generation windows”. The U36 model is a cornerstone of this range, providing powerful energy management for high-capacity sites.
Advanced Yield & Smart Management
The U36 is engineered to capture every possible watt of energy. Featuring 4 independent MPPT trackers with a wide operating voltage range of 160V to 1000V, it handles varied roof orientations with ease. It includes a Smart I/V Curve Function for precise diagnostics and PID Recovery to prevent performance degradation over time, ensuring your investment remains profitable for years.
Commercial-Grade Durability & Cooling
Built to last in extreme conditions, the U36 features an IP66-rated housing and C5 anti-corrosion protection. Unlike smaller residential units, the U36 utilizes an efficient active Fan cooling system to maintain stable thermal performance even at its full 36kW output. It is also fully compatible with high-power bifacial PV modules.
Uncompromising Safety & Monitoring
Safety is a core priority for FoxESS. The U36 comes standard with integrated Type II Surge Protective Devices (SPD) on both the DC and AC sides. It also features PV String Current Monitoring and a built-in AFCI (Arc Fault Circuit Interrupter) to significantly reduce fire risks. For monitoring, the system uses LED and Bluetooth+App connectivity, with optional WLAN/Ethernet or 4G modules for remote tracking via the web portal.
Core Advantages:
- High Current Input: 16A input current makes it compatible with modern, high-power bifacial modules.
- Flexible Communication: Supports RS485, Ripple control, E-stop, and DRM0 for full grid and site integration.
- Global Compliance: Fully meets international standards including EN 62109-1/2 and EN 61000-6-1/2/3/4.
