The SMA Sunny Tripower CORE2, also known by its model name STP 110-60, is a three-phase string inverter designed specifically for commercial and industrial solar projects. With an impressive output of 110 kW AC, this device is the big brother of the smaller residential variants, such as the Sunny Tripower Smart Energy, and is especially suitable for installations on commercial rooftops or large ground-mounted setups heading toward the megawatt level.
What makes the CORE2 special is its flexibility. Thanks to twelve MPPT trackers and twenty-four connectable strings, it can handle different module orientations and shading conditions effortlessly. This makes it ideal for more complex installations where panels do not all have the same location or inclination. In the process, the system can control a PV array of up to 165,000 Wp, offering tremendous scalability.
In terms of efficiency, the CORE2 is also strong. The maximum efficiency is 98.6 percent, with a European efficiency of 98.4 percent. In addition, the inverter features SMA ShadeFix, software that optimizes yield when there is partial shade. To increase reliability, SMA Smart Connected is built in, a smart monitoring service that identifies faults early and notifies installers or owners immediately.
In terms of safety, the CORE2 also leaves nothing to be desired. The inverter has an arc-fault circuit interrupter ( AFCI) function as standard, which prevents arcing and minimizes fire risks. In addition, integrated Type I and II surge protectors are provided to keep the system protected against lightning strikes or grid disturbances.
The CORE2 is not only powerful and safe, but also future-proof. It is part of the SMA Energy System Business and can be fully integrated with platforms such as ennexOS and Sunny Portal. This makes it possible to organize energy management, monitoring and maintenance centrally. For installers, this means that they can easily plan and simulate a customized system using Sunny Design.
