- Vendor: SMA
Specifications
Product Description
The SMA Sunny Tripower X 12kW STP12-50 Three-Phase Solar Inverter is the new generation of grid-tied inverters for advanced commercial and residential self-consumption. It integrates a system manager with direct access to Sunny Portal (ennexOS), allowing you to configure, monitor, and optimize the entire plant from a single device. Its high efficiency of up to 98.2% and dynamic power control make this inverter the ideal option for three-phase installations that require reliability, safety, and total control.
Main Features
- 3 independent MPPTs with 2 strings per MPPT, 24 A per MPPT (Isc max. 35 A), ready for high-current modules.
- MPPT range 206–800 V (maximum input voltage 1000 V, nominal Vdc 580 V) for flexible designs in different configurations.
- Admissible PV power 18 kWp STC and nominal AC power of 12 kW at 230/400 V three-phase (50/60 Hz).
- Maximum efficiency 98.2% (EU 97.6%) with OptiCool cooling and sound level < 65 dB(A).
- Advanced safety: SMA ArcFix (AFCI), optional type II DC protection, residual current monitoring, and reverse polarity.
- Complete connectivity: 2×Ethernet, WLAN, Modbus (SMA/SunSpec), Speedwire, 6 digital inputs, and multifunction relay.
Advantages or Benefits
- Centralized management: the integrated system manager coordinates up to 5 inverters (135 kVA) and 1 energy meter for precise feed-in control (SMA Dynamic Power Control).
- More real energy: the ShadeFix software optimizes production with partial shading, and the I-V diagnosis speeds up maintenance.
- Availability and support: SMA Smart Connected with proactive monitoring and automatic notifications to the installer.
- Robust and industrial: IP65 enclosure, -25 °C to +60 °C, 100% RH without condensation; perfect for demanding outdoor environments.
- Scalable: ready for future energy management functions via expansion slot.
Purpose or Applications
Ideal for three-phase self-consumption in SMEs, businesses, logistics warehouses, agribusiness, and energy communities. Also suitable for upgrading industrial rooftops with high-current modules. This is not a hybrid inverter: storage and back-up are managed through specific SMA controllers/solutions.
