SolarEdge S440 440Watt 60VDC Power Optimizer For Residential Installation

Features

The SolarEdge S440 Power Optimizer maximizes energy production and efficiency in residential solar systems while ensuring superior safety and simplified installation. It delivers 99.5% efficiency, mitigates module mismatch losses from shading or manufacturing variations, and enables faster installations with streamlined cable management and single-bolt assembly. Module-level voltage shutdown ensures safety for installers and first responders, while abnormal connector behavior detection enhances reliability. The optimizer supports bifacial PV modules and flexible system designs for optimal space utilization.

Technology and Overview

The SolarEdge S440 Power Optimizer is a module-level solution designed to optimize energy output and enable advanced monitoring. With a 99.5% maximum efficiency, it reduces power losses and enhances performance at the module level. It incorporates advanced safety features, including module-level voltage shutdown to a safe 1 Vdc when the inverter or grid power is off, ensuring safety for installers and emergency responders. The optimizer also detects abnormal connector behavior, improving system safety and reliability.

Installation and Compatibility

The S440 is designed for easy installation and works seamlessly with SolarEdge residential inverters. It supports parallel strings with different lengths or orientations, works with bifacial PV modules, and offers simplified mounting using compact MC4 connectors. The IP68-rated enclosure ensures durability in harsh environments, operating reliably between -40°C and +85°C with power de-rating at higher temperatures.

System Design

The S440 supports 8 to 25 optimizers per string and is compatible with single-phase and three-phase SolarEdge inverters for 230/400V or 277/480V grid systems. This flexibility allows for optimized performance in residential solar installations.
