SolarEdge S440 Power Optimizer – Module-Level MPPT

Get a faster return on your solar investment with the SolarEdge S440 power optimizer. A sleek, efficient, and safety-focused device, the power optimizer is designed to elevate the performance of your solar power system, simplify the installation process, and deliver long-term reliability.

The SolarEdge S440 is a high-precision DC-to-DC converter that bolsters energy production through Maximum Power Point Tracking, or MPPT, on each individual solar module. This intelligent method of optimization ensures that each panel consistently operates at its peak efficiency—even under partial shading, module mismatch, or dirty solar cells. This gives you a higher energy yield throughout the system and an improved ROI. This power optimizer can even achieve a peak efficiency of 99.5% under the right conditions.

Safety and peace of mind are also paramount with this device. The SolarEdge S440 features the company’s advanced SafeDC rapid shutdown capability, which automatically reduces module output voltage to a single volt when the inverter or grid goes offline. This significantly enhances safety during installation, maintenance, and in emergencies. The new Sense Connect technology in this power optimizer improves safety even further, detecting any sign of overheating or unusual behavior and triggering an immediate shutdown when needed. It will then alert you to pinpoint the issue location via the monitoring app.

The SolarEge S440 power optimizer’s design includes streamlined cable layouts (including short output cables and a longer positive lead), keeping connectors close to the module, reducing snag risks, and simplifying assembly with single-bolt mounting and standard MC4 connections.

In addition to being efficient, the SolarEdge S440 is also durable, and built to endure a variety of harsh environments. It operates across a broad voltage range, from 8 to 60 volts, and handles up to 15 amps of output current. It can maintain functionality in temperatures from –40 °F to 185 °F, and has an IP68 and NEMA 6P-rated enclosure. With UV and fire resistance built in, this power optimizer is sure to live a long and productive life in your solar power system.

For those users that prioritize monitoring and maintenance, the power optimizer offers you module-level visibility via the SolarEdge monitoring platform. This allows installers and homeowners alike to detect and resolve issues quickly, minimizing downtime and protecting your system’s performance. All of this efficiency, convenience, and durability is backed by a 25-year warranty, proving SolarEdge’s confidence in this product throughout the years.

With advanced energy optimization, rigorous safety features, streamlined installation, and durable engineering, the SolarEdge S440 power optimizer is ideal for homeowners who demand maximum performance, longevity, and peace of mind from their sol
