Description
SolarEdge S440 Power Optimizer 440W 60V - S440The SolarEdge S440 Power Optimizer is a module level DC power optimizer designed specifically for residential solar systems using SolarEdge inverters. It mitigates all types of module mismatch loss from manufacturing tolerances to partial shading while delivering 99. 5% efficiency. With module level voltage shutdown for installer and firefighter safety, it is ideal for maximizing energy harvest in off grid or grid interactive residential PV systems.
The SolarEdge S440 Power Optimizer is a module-level DC power optimizer designed specifically for residential solar systems using SolarEdge inverters. It mitigates all types of module mismatch loss – from manufacturing tolerances to partial shading – while delivering 99.5% efficiency. With module-level voltage shutdown for installer and firefighter safety, it is ideal for maximizing energy harvest in off-grid or grid-interactive residential PV systems.
Key Features & Benefits
99.5% Superior Efficiency: Maximizes energy harvest by mitigating mismatch losses from shading, soiling, and manufacturing tolerances.
Module-Level Voltage Shutdown: Provides installer and firefighter safety by reducing output voltage to 1V per optimizer when disconnected from the inverter or during rapid shutdown.
Detects Abnormal PV Connector Behavior: Identifies potential safety issues to prevent arcing and connector failures (functionality subject to inverter model and firmware).
Flexible System Design: Allows parallel strings of different lengths and orientations for maximum space utilization.
Simplified Installation: Faster cable management and easy assembly using a single bolt.
Compatible with Bifacial PV Modules: Works with standard and bifacial modules for design flexibility.
IP68 Rated: Fully sealed against water and dust for long-term outdoor reliability.
25-Year Warranty: Backed by a 25-year warranty for long-term peace of mind.
