Modelo: STP25-50- Sku: SMAINVE036
- Vendor: SMA
Specifications
Product Description
The SMA Sunny Tripower X 25kW STP25-50 Three-Phase Solar Inverter is the top option in the Tripower X family for grid-connected plants that require power, efficiency, and centralized control. Its power electronics with OptiCool cooling and a robust IP65 enclosure design ensure reliability in demanding outdoor environments. The integrated system manager allows coordination of up to five inverters (135 kVA), optimization of injection, and compliance with grid requirements through SMA Dynamic Power Control and advanced reactive power functions, all with native monitoring in Sunny Portal (ennexOS).
Main Features
- Nominal power 25 kW at 230/400 V three-phase, ideal for industrial rooftops and energy communities.
- 3 independent MPPTs with 2 strings per MPPT, current per tracker of 24 A (max Isc 35 A) prepared for high-current modules.
- Maximum input voltage 1000 V; nominal Vdc 580 V; wide MPPT window (≈ 257–800 V) for flexible designs and long strings.
- Maximum efficiency ≈ 98.2 % (EU ≈ 98 %), sound level < 65 dB(A), and high power density.
- Active protection with SMA ArcFix (AFCI), RCMU, optional type II DC protection, reverse polarity detection, and PID recovery function.
- Comprehensive communications: 2×Ethernet, WLAN, Modbus/SunSpec over Speedwire, RS485 (module), 6 digital inputs, and multifunction relay.
Advantages or Benefits
- Optimized production with ShadeFix, which mitigates losses due to shading and mismatches, and I-V diagnosis for predictive maintenance.
- Management and scalability: the integrated manager allows growth by clusters, simplifying control of feed-in and reactive power.
- Industrial reliability: IP65 enclosure, operation from −25 °C to +60 °C and 100 % RH; prepared for harsh environments.
- Low total cost of ownership thanks to SMA Smart Connected, with automatic alarms and proactive installer support.
- Integration in the SMA ecosystem (EV Charger, meters, gateways) for smart energy and e-mobility solutions.
Purpose or Applications
Designed for high-power three-phase self-consumption in industrial buildings, hotels, agri-food sector, photovoltaic carports, and energy communities. It is not a hybrid; for systems with battery or back-up, integrate specific SMA controllers and inverters in AC coupling.
