SolarEdge S440 Power Optimizer – 440W, 60V, MC4 Compatible

Maximize energy harvest with module-level optimization.

The SolarEdge S440 Power Optimizer is a DC/DC converter designed to attach directly to your solar modules. By constantly tracking the Maximum Power Point (MPPT) of each individual module, the S440 mitigates power losses caused by shading, soiling, or module mismatch, ensuring your system produces the maximum energy possible.

The Smart Alternative to Microinverters

The S440 offers the best of both worlds: the granular monitoring and performance of a microinverter, combined with the durability and cost-efficiency of a central inverter system.

Unlike microinverters, which perform complex DC-to-AC inversion on the roof (exposing sensitive electronics to extreme heat), SolarEdge optimizers simply condition the DC power. This results in significantly higher reliability and a longer lifespan.

Key Features

• Superior Efficiency: Boasts a peak efficiency of 99.5% for minimal power loss.
• Module-Level Monitoring: View performance data for every single panel in your array via the SolarEdge monitoring platform.
• Design Flexibility: Allows for strings of uneven lengths and multiple orientations, making it perfect for complex roof lines.
• Peace of Mind: Backed by a 25-year manufacturer warranty, ensuring your investment is protected for the life of the system.
