Product description

The SMA Sunny Boy 2.5kW Single-Phase Solar Inverter SB2.5-1VL-40 is the top option in the SB-1VL-40 family for small and medium rooftops seeking performance, reliability, and full connectivity for on-grid self-consumption. With 2.5 kW of nominal power, maximum efficiency of 97.2%, and IP65 enclosure, this transformerless string inverter operates by natural convection and offers quick start-up via web interface, integrating seamlessly into the SMA digital ecosystem (Sunny Portal and Sunny Places) thanks to WLAN/Ethernet, Webconnect, and Modbus (SMA/SunSpec).

Main features

Output power: 2.5 kW (2.5 kVA) at 230 V single-phase; nominal current approx. 10.9–11 A.
PV input: 1 MPPT / 1 string; MPP window 260–500 V; max. input voltage 600 Vdc.
Input currents: I_max 10 A per string; I_SC max. 18 A.
Efficiency: 97.2 % max. (European efficiency ~96.5 %); power factor 1, adjustable 0.8 ind…0.8 cap.
Protection and construction: IP65, transformerless, natural convection cooling, sound level < 25 dB.
Integrated connectivity: WLAN and Ethernet (Speedwire), Webconnect, and Modbus SMA/SunSpec; SMA Smart Connected service with proactive monitoring.

Advantages or benefits

More energy on small roofs: its MPP range from 260 V enables short strings with high-power modules and varied orientations.
Silent and durable: fanless design, IP65 sealing, and professional-grade components for long outdoor service life.
Express start-up: commissioning assistant via browser; SUNCLIX connectors speed up wiring.
Total control: free cloud monitoring (Sunny Portal/Sunny Places), automatic reports, and notifications with Smart Connected.
Home automation/energy integration: compatibility with Modbus/SunSpec meters and feed-in control with SMA Energy Meter/Home Manager 2.0.

Purpose or applications

Ideal for single-family homes, apartments with roofs or terraces, small businesses, and expansions of existing systems. A balanced on-grid inverter for arrays of 6–9 modules depending on power and orientation, designed to maximize self-consumption, reduce purchase peaks, and provide clear data to the end user.
