SMA Sunny Boy 1.5 – Solar inverter

Product code
EUR 6990
Sample Flyer Ask for info

With a nominal power of 1.5KWAC, the transformer-less inverter, which provides one MPPT and a peak efficiency of 97.2%, offers a suitable solution for small size photovoltaic system owners. It enables grid-injection as well as self-consumption, following the new trend in solar inverters. Integrated Ethernet and WLAN interfaces offer multiple possibilities for communication and data monitoring. Delivered without display, the integrated user interface makes possible to monitor system data on any smartphone, tablet or PC.

The system uses a specific power module from Vincotech and electrolytic capacitors from Epcos.

The WLAN board integrates a SMD WiFi Module, a chip Antenna but also a 3-axis MEMS Accelerometer.

Based on a complete teardown analysis, the reverse costing report of the SMA Sunny Boy SB1.5-1VL40 Inverter provides the bill-of-material of the product and an estimation of the production cost of the solar inverter.
