Product Description

The SMA Sunny Tripower 8kW STP8.0-3AV-40 Three-Phase Solar Inverter is designed for homes and small businesses with a 3×400 V grid to achieve maximum performance from their panels. With a maximum efficiency of 98.3%, IP65 enclosure, and “plug & play” commissioning via integrated web interface (WLAN/Ethernet), this string inverter offers an outstanding combination of power, reliability, and ease of use. Its 2 MPPT (input A with up to 2 strings and input B with 1 string) allow optimization of rooftops with different orientations or inclinations. The OptiTrac Global Peak shading management and compatibility with TS4-R module optimizers help maintain production under real conditions.

Main Features

Nominal AC power: 8 kW (8 kVA) at 3/N/PE 230/400 V; I_AC,max 3×12.1 A.
2 independent MPPT; strings per MPPT: A:2 / B:1.
PV input: V_MPP 260–800 V; V_min/V_start 125/150 V; V_oc,max 1000 V.
I_max per input A/B: 20 A / 12 A; I_SC,max A/B: 30 A / 18 A.
Recommended PV generator: up to 15 kWp.
Connectivity: WLAN, Ethernet (Speedwire), RS-485, Modbus SMA/SunSpec, Webconnect.

Advantages or Benefits

Superior performance with 98.3% efficiency and advanced MPP tracking for more annual kWh.
Design flexibility: two MPPT (A:2/B:1) to combine east/west, different slopes, or strings of different lengths.
Quick installation: 20.5 kg, SUNCLIX connectors, and commissioning assistant from mobile or tablet.
Long-term reliability: IP65, −25…+60 °C, convection cooling (no fans), and typical noise of 30 dB(A).
Intelligent management: dynamic feed-in limitation 0–100%, monitoring in Sunny Portal/Places, and proactive alerts with Smart Connected.

Purpose or Applications

Ideal for three-phase self-consumption in large homes or small businesses with photovoltaic fields of up to ~15 kWp. Its wide MPP window (260–800 V) facilitates the use of high-power modules and complex roof designs, as well as future expansion with storage and load management.
