Sunny Boy 4.0

The new Sunny Boy 4.0 succeeds the world‘s most installed residential string inverter, the Sunny Boy 3000 – 5000TL. It is more than just a PV inverter.

For the first time the new Sunny Boy 3.0 – 5.0 solution comes with SMA Smart Connected that offers PV system owners and installers true comfort and ease. The automatic inverter monitoring by SMA analyzes operation, reports irregularities and minimizes downtime.
