🔹 Key features STP4.0-3AV-40
- Power: 4 kW rated AC output power.
- MPP trackers: 2 independent MPP trackers, which is ideal when you have solar panels in two different orientations/strings.
- Efficiency: Up to about 98% efficiency, so little energy loss.
- Three-phase connection: Distributes the generated power nicely among all phases, which is good for grid balance and larger powers.
- ShadeFix technology: Optimizes yield under (partial) shade without the need for additional optimizers.
- SMA Smart Connected: Online monitoring and automatic fault detection via the Sunny Portal.
