SB 6.0

The SMA Sunny Boy SB 6.0 (SB6.0-1AV-41) is the 6 kW single-phase inverter — the most powerful in the Sunny Boy 3.0–6.0 series — designed by SMA Solar Technology for high-power residential photovoltaic systems. With a maximum PV array power of 9,000 Wp and a European efficiency of 96.6%, it is the optimal choice for homes with high energy consumption, large available roof surfaces, or systems combined with heat pumps and electric vehicle charging, where you want to maximize single-phase production before considering a three-phase inverter.

2 Independent MPPTs — Optimal Management of Complex Roofs

The SB 6.0 features 2 independent MPP trackers (input A and input B), each capable of connecting 2 strings. This architecture allows you to manage separately roof sections with different orientations or inclinations, maximizing overall production. The MPP range goes from 210 V to 500 V, with a maximum DC voltage of 600 V and a maximum AC output current of 26.1 A — the highest in the series.

SMA OptiTrac Global Peak and TS4-R — Shading Under Control

Shading management operates on two levels:

• SMA OptiTrac Global Peak (integrated) — an algorithm that identifies the global maximum power point on the I-V curve even in the presence of multiple local maxima due to partial shading
• Integrated TS4-R Communication — native compatibility with SMA TS4-R module optimizers, which can be installed selectively only where needed without replacing the inverter

SMA Smart Connected — Proactive Monitoring and Replacement

By registering the system on Sunny Portal, SMA Smart Connected is automatically activated: SMA monitors the inverter 24/7 and, in case of an anomaly, proactively notifies the installer and owner via email. If replacement is necessary, SMA ships a replacement inverter within 1–3 business days from diagnosis — with guaranteed compensation in case of delay. Available in Italy at no additional cost.

Installation and Communication

Commissioning is done via an integrated web interface accessible from a smartphone, tablet, or notebook, with no dedicated software required. Communication interfaces include:

• WLAN — direct connection to the home router for online monitoring
• Ethernet (SMA Speedwire) — for wired networks and connection to SMA Home Manager / Data Manager
• RS485 — for integration with BMS or building automation systems
• Protocols: Modbus SMA/SunSpec, Webconnect, SMA Data, TS4-R

Free online monitoring via Sunny Portal and Sunny Places.

Expandability — Storage and Energy Management

The SB 6.0 integrates natively with the SMA residential ecosystem:

• SMA Sunny Home Manager 2.0 — intelligent energy management with AI to maximize self-consumption
• Compatible SMA Storage Systems — expandable with batteries at any time after installation
• SMA EV Charger — integrated electric vehicle charging within the home energy system
• Dynamic Active Power Limitation — reduces grid withdrawals during periods of excess production
