Description
The SMA Sunny Highpower PEAK3 SHP 125-US-21 is a 1,500VDC utility-grade string inverter engineered for large-scale solar power plants, delivering best-in-class power density, modular scalability, and the lowest possible balance-of-system costs.
Key Features
- 1,500VDC Modular Architecture Scalable building block design with best-in-class performance maximizes land usage and reduces BOS costs for utility-scale solar deployments.
- High Power Density & Compact Design Optimized physical footprint maximizes transportation and logistical efficiency while delivering 125KW of nominal AC output power.
- SMA Smart Connected Technology Field-proven proactive O&M monitoring simplifies service, reduces lifetime maintenance costs, and is available at no cost for inverters under warranty.
- ennexOS Energy Management Platform Award-winning cross-sector energy management platform enables centralized commissioning, control, and comprehensive plant-level visibility.
- 25-Year Design Life Manufacturer-declared design life with optional warranty extensions to 25 years ensures long-term investment protection for utility and commercial power plant developers.
The SHP 125-US-21 delivers 125KW nominal AC power at 98.5% CEC efficiency, accepting up to 250kWp DC array power across a 684–1500V MPPT operating range with a maximum input current of 180A. Its OptiCool variable-speed forced convection cooling system ensures reliable thermal performance across a -25°C to +60°C operating range.
Certified to UL 62109, UL 1998, and CAN/CSA-C22.2 No.62109, and compliant with IEEE 1547:2018, UL 1741-SA, CA Rule 21, and HECO Rule 14H, the PEAK3 meets all major US utility grid interconnection requirements. Advanced grid support capabilities include L/HFRT, L/HVRT, Volt-VAr, Volt-Watt, Frequency-Watt, and Ramp Rate Control for full utility compliance.
Dual Ethernet ports with SMA Speedwire, SMA Modbus, and SunSpec Modbus protocols are included as standard, with SMA Sunny Portal monitoring provided at no cost for the lifetime of the system. Rack-mount installation with terminal lug DC connections up to 600 kcmil and screw terminal AC connections up to 300 kcmil CU/AL ensure professional-grade field integration.
