S650A Power Optimizer
Designed for short string residential rooftops
- Specifically designed to work with compatible SolarEdge residential inverters
- Small and multifaceted rooftops segment solution:
Reduced number of modules per inverter
Extended voltage, reducing yield factor losses - Improved design flexibility of multifaceted, complex roofs by reducing yield factor losses on the entire system
- Superior efficiency (99.5%)
Mitigates diverse types of module mismatch loss, from manufacturing tolerance to partial shading
Faster installations with simplified cable management and easy assembly using a single bolt - Flexible system design for maximum space utilization
- Compatible with a wide range of modules, including high-powered and bifacial PV modules Advanced safety:
- Patented Sense Connect technology- designed to automatically detect and prevent potential electric arcs at the connector level before an arc is created*
- Patented SafeDC™ – module-level voltage shutdown, for installer and firefighter safety

PV System Design Using a SolarEdge Inverter(4) SolarEdge Home Wave / Home Hub Inverters – Three Phase for 230/400V Grid(5) Units Minimum String Length (Power Optimizers) 10 Maximum String Length (Power Optimizers) 50 Maximum Continuous Power per String 11,250 W Maximum Allowed Connected Power per String
(In multiple string designs, the maximum is permitted only when the difference in connected power between strings is 2,000W or less)13,500(6) W Parallel Strings of Different Lengths or Orientations Yes - It is not allowed to mix S650A Power Optimizers with any other Power Optimizers on the same inverter.
- S650A is only compatible with:
• SolarEdge Home Wave Inverter – Three Phase (SExxK-RW0TEBxN4) from firmware version 4.22.XX and above, for inverters produced after WW42/2020. You can find the production date in the serial number on the inverter label (S/N: SJWWYY-xxxxxxxxx-xx).
• SolarEdge Home Hub Inverter – Three Phase (SExxK-RWB48BFN4) from firmware version 4.22.XX and above. - If the inverter’s rated AC power ≤ maximum nominal power per string, then the maximum power per string will be able to reach up to the inverter’s maximum input DC power. Refer to the Single String Design Guidelines application note.
