Grid Inverter SMA Single-Phase 1.5 kVA – SB1.5-1VL-40
The SMA SB1.5-1VL-40 (Sunny Boy 1.5) grid-connected inverter is designed for small single-phase photovoltaic installations, with a compact format and an extended input range to easily adapt to residential configurations. Its OptiTrac Global Peak technology improves MPPT tracking in the event of partial shading in order to stabilise production.
- Technical specifications: AC power 1500 VA (1500 W), 1 MPPT, max PV voltage 600 V, max efficiency 97.2% (European 96.1%), convection cooling, IP65 rating.
- Compatibility: single-phase 230 Vac grid, MPPT range 160 to 500 V, SUNCLIX DC connectors, integrated protection (DC disconnection, grid monitoring and earth fault).
- Benefits: It optimises production on small roofs, even in partially shaded conditions, while simplifying installation thanks to its quick DC connection.
SMA Sunny Boy 1.5 solar inverter: Small, powerful and easy to install

Description

Optitrac technology
OptiTrac Global Peak is an additional function of the proven "OptiTrac" MPP tracker and is activated on this inverter.
It is used for partially shaded photovoltaic systems. Even in this configuration, this special operating mode guarantees continuous operation of the panels at the point of maximum power, with no noticeable influence on yield (losses < 0.2%). In other words: even in the event of shading, the panels operate correctly.
