SolarEdge S650A Power Optimiser

• Manufacturer SolarEdge Technologies

Designed for short-string residential roofs, the SolarEdge S650A Power Optimizers are ideal for small-scale systems on complex roofs with multiple orientations - enabling strings as short as ten modules without sacrificing efficiency or safety. 

With an efficiency of 99.5%, the S650A Power Optimizers maximise the energy yield from each solar panel by mitigating diverse types of module mismatch loss from manufacturing tolerances to shading; facilitate module-level monitoring and enable advanced safety features that surpass industry standards. 

These Power Optimizers are compatible with the SolarEdge Home Wave and Home Hub Three Phase inverters, specifically:  

SolarEdge Home Wave Inverter – Three Phase (SExxK-RW0TEBxN4) from firmware version 4.23.XX and above, for inverters produced after WW42/2020.  

SolarEdge Home Hub Inverter – Three Phase (SExxK-RWB48BFN4) from firmware version 4.23.XX and above.  

The Power Optimizers have a rated input DC power of 650W making them compatible with a wide range of modules including high-powered and bifacial modules (the rated power of the module at STC must not exceed the Power Optimizer rated input. Modules with up to +5% power tolerance are allowed). 

Note: The  S650A Power Optimizer cannot be mixed with any other type of Power Optimizer on the same inverter.  

Key performance advantages 

String length (Power Optimizers) - 10-38 

Support High-powered modules – 650Wp input power, 15A Isc. and an input voltage of 80V.  

Built-in safety technology 

SafeDC™ rapid shutdown – each SolarEdge S650A Power Optimizer reduces its output to around 1V when the inverter or AC supply is off, safeguarding installers and first-responders. 

S-Series Sense Connect arc prevention – patented technology that identifies abnormal thermal events in the Power Optimizer connector to prevent electric arcs from forming*. By stopping the power flow, the inverter switches the system to safe mode and reduces the voltage; the faulty connector location is visible in the system layout on the Monitoring Platform and an event notification is sent via SetApp and the SolarEdge Monitoring Platform. 

100% system visibility enabled with module-level monitoring  

Faster installation with simplified cable management, accessible connectors and straightforward assembly using a single bolt. 

Flexible PV system design for maximum utilisation of roof space. 

Full standards compliance – IEC 62109-1/-2, VDE-AR-E 2100-712 fire safety, FCC Class B EMC, and UL 1741 listing meet global code requirements. 

*Function requires compatible SolarEdge inverter firmware. 

Installer benefits 

Greater design flexibility – enable more complex project layouts by allowing solar panels to be placed at different orientations and tilts. 

Faster installs – simplified cable management and a single mounting bolt reduce rooftop time. 

Lower O&M costs – module-level monitoring and automatic system alerts with remote troubleshooting and diagnosis allow you to pinpoint issues, minimise system downtime and streamline operations.
