SMA Sunny Boy 5.0kW Solar Inverter - Single Phase with Smart Connect

The SMA Sunny Boy 5.0kW Solar Inverter - Single Phase with Smart Connect (MPN: SB5.0-1AV-41) is a transformerless grid-tied inverter for residential PV systems, combining dual MPPTs, integrated web connectivity and SMA Smart Connected proactive monitoring.

Product Description

Designed for single-phase self-consumption systems up to 5kW, the Sunny Boy 5.0 converts DC from the PV array into grid-compliant AC with up to 97% efficiency. The compact, lightweight design supports one-person installation, while built-in WLAN/Ethernet and web server enable fast commissioning via smartphone, tablet or laptop and ongoing monitoring through Sunny Portal and SMA Energy App.

Key Features

• SMA Smart Connected: Free automated inverter monitoring with proactive fault notification and fast replacement service.
• Dual MPPT: 2 independent MPP trackers for flexible string design and partial shading management (SMA ShadeFix compatible).
• Integrated web server: Direct access via browser over WLAN or Ethernet for setup and diagnostics.
• Battery-ready: AC-coupled storage (e.g. Sunny Boy Storage) can be added later without replacing the inverter.
• Optimizer compatibility: Fully compatible with Tigo TS4-R optimisers for module-level optimisation and monitoring.
• Quiet, fanless design: Natural convection cooling with low operating noise.
