Description
The SolarEdge U650 is a high-efficiency residential power optimizer designed for North American PV systems, supporting solar modules up to 650W DC STC rating (8V-60V, 15A). Featuring MC4 compatibility and a 90" PV output wire, this UL-certified add-on maximizes energy throughput by tracking each module’s Maximum Power Point and monitoring performance data via the SolarEdge monitoring portal.
Manufactured in the USA, the U650 qualifies for domestic content tax credits with compatible SolarEdge inverters. It delivers 99.5% efficiency, reducing power loss from shading or module mismatch. Simplified installation with a single-bolt design and advanced safety features—such as Sense Connect technology and SafeDC™—ensure reliability and compliance with NEC safety standards.
Compatible with various PV modules, including high-powered and bifacial options, the U650 supports flexible designs and operates in extreme conditions (-40°C to +85°C) with an IP68-rated enclosure. Backed by a 25-year warranty, it is a durable, efficient solution for solar energy systems.
