Product Description

The SMA Sunny Tripower 5kW STP5.0-3AV-40 Three-Phase Solar Inverter is a high-performance string inverter designed for homes and small businesses with a three-phase grid seeking to maximize photovoltaic production and system control. With 5 kW (5 kVA) nominal power, a maximum efficiency of 98.2%, and an IP65 enclosure, this model from the Sunny Tripower 3.0–6.0 range combines “made in Germany” electronics with full connectivity (WLAN/Ethernet, Webconnect, and Modbus SunSpec) and proactive monitoring service SMA Smart Connected. Its 2 MPPTs allow operation with two independent orientations and make use of complex rooftops, while the wide operating range facilitates the use of next-generation modules.

Main Features

Continuous output power: 5 kW (5 kVA) at 3/N/PE 230/400 V; max current 3×7.6 A.
2 MPPT (A/B) with 1 string per tracker; MPP range 215–800 V; max Voc 850 V.
Current per input: I_max 12 A, I_SC 18 A (each MPPT).
Efficiency: 98.2% max / 97.4% EU; power factor 1 (adjustable 0.8 ind…0.8 cap).
Protection IP65, transformerless design, convection cooling, ≈17 kg.
Communications: WLAN/Ethernet (Speedwire), Webconnect, Modbus SMA/SunSpec, RS-485.
Shade management ShadeFix/OptiTrac and compatibility with TS4-R optimizers.

Advantages or Benefits

Superior performance thanks to 98.2% efficiency and advanced MPP tracking even with partial shading.
Design flexibility: the 2 MPPTs allow east/west or different tilt combinations without production loss.
Total connectivity and control via Sunny Portal/Places, Modbus integration, and automatic notifications with SMA Smart Connected.
Reliability and low maintenance: IP65, silent convection operation, and robust outdoor electronics.
Quick installation: 17 kg, SUNCLIX terminals, and web assistant for commissioning in minutes.

Purpose or Applications

Perfect for three-phase self-consumption projects in homes and small businesses with PV fields up to ~10 kWp, grid feed-in control, and the need for online monitoring. Its MPP window of 215–800 V adapts to strings with high-power modules and compact designs on residential rooftops.
