Description
The Sineng SN40PT 40kW Three Phase Grid-Tie Inverter is a top-tier power conversion solution for commercial and industrial (C&I) solar applications. By integrating “High Yield” technology with “High-Performance Management,” this inverter ensures your photovoltaic system delivers consistent and safe energy in the most demanding environments.
Unmatched Industrial Yield with 3 MPPTs
Designed for large-scale installations, the SN40PT features three independent MPPT trackers, allowing for optimized energy harvest on roofs with multiple orientations or varying shading conditions. It supports an incredible 60kWp of DC input, enabling significant array oversizing to maximize energy production during low-light hours. This model is also fully compatible with bifacial PV modules, which capture light from both sides to further increase total system ROI.
Advanced Safety & PID Recovery
Safety and long-term reliability are built into the core of the SN40PT. It features a built-in PID (Potential Induced Degradation) recovery function, which actively restores panel performance and extends the lifespan of your solar modules. For total system security, the inverter includes an arc-fault circuit-interrupter (AFCI) and Type II Surge Protective Devices (SPD) on both DC and AC sides to guard against electrical fires and lightning strikes.
Robust Engineering & Smart Management
Encased in an IP66-rated chassis with C5 anti-corrosion certification, the SN40PT is built to withstand extreme weather, dust, and salt-heavy environments. Its Smart Fan Cooling system ensures the unit stays at optimal temperatures even during its 1.1 times continuous output overload phase. Technicians can easily perform local and remote maintenance via the mobile APP, utilizing accurate string current detection and Smart I/V curve scanning to diagnose issues without site visits.
