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.

Favorite Socks Ever
Size: Medium, Color: Black/Assorted, Size: Medium, Color: Black/Assorted
I absolutely love these socks, they compress in the middle which is my favorite thing about them! Keeps them from slipping off my feet and also adds support, love love love how they feel and how long they last! This is my second pack that I’ve purchased, I had the multi colored ones before and they’ve lasted me two years before finally starting to wear out and fade and get holes. Definitely going to be routinely buying these every year. Good to wear with my work out shoes...winter boots, Nike sandals, and my everyday adidas sneakers. These are so worth it!

Great ankle socks that stay put at a great price!!
Size: 6-9, Color: Assorted
These are great! I have been looking for a low profile ankle sock that is thinner but doesn’t ride down. (Picky, right?) I try to walk 5-7 miles on my days off. So it’s very important for me to not have to stop every couple of hundred yards, bend down, fix socks, then continue on my way while grumbling about NOT GREAT socks. These are not those socks. They really do stay put!!! And enough cushion to be comfortable also. So definitely a repeat!!

Great quality, no holes or fading!
Size: Medium, Color: Black/Assorted
I purchased these socks a couple years ago and love them so much that I just recently purchased them again! They fit perfectly, don't make my feet sweaty, and hit the ankle at the right spot. The material is so good that over years they have not faded and even though I wear the same few pairs every day, they have no signs of thinning or holes! These are the ONLY socks that I buy. I have the black ones as well as the multi-colored ones. I will never buy another brand or style again!
