SMA Sunny Tripower X 20 kW 3 Phase 3 MPPT (STP 20-50)

The SMA Sunny Tripower X 20 kW 3 Phase 3 MPPT (STP 20-50) is a high‑efficiency three‑phase string inverter engineered for commercial and industrial PV systems, delivering up to 20 kW of AC power with maximum efficiency around 98% and a wide DC input range up to 1000 V for flexible system design. With three independent MPP trackers and multistring capability, it optimizes energy yield from complex roofs, while advanced grid management features such as Integrated Plant Control and 24/7 reactive power support (Q on Demand) ensure grid‑compliant, future‑proof operation. Robust safety is built in through DC reverse‑polarity protection, ground fault and grid monitoring, optional Type II DC surge arresters, and transformerless OptiCool thermal management in an IP65 outdoor-rated enclosure operating from -25°C to +60°C. The Sunny Tripower X supports modern communication and monitoring via Speedwire/Webconnect, SMA and SunSpec Modbus interfaces, and optional RS485, integrating seamlessly with Sunny Portal for professional remote supervision. For long‑term peace of mind, SMA backs the Tripower X platform with a standard 5‑year factory warranty, extendable to 10, 15, or 20 years to match project requirements.
