SolarEdge S650A Power Optimiser

The SolarEdge S650A is a residential power optimiser for short-string rooftop PV installations. It is used with compatible SolarEdge residential inverters to manage module-level output and support system design on rooftops with shading or layout complexity.

Key Features
Residential short-string application

Designed for short-string residential rooftop PV systems.

High conversion efficiency

Maximum efficiency is 99.5% with weighted efficiency of 98.6%.

Module mismatch mitigation

Helps reduce losses caused by manufacturing tolerance and partial shading.

Outdoor-rated enclosure

IP68 protection and -40 to +85 °C operating temperature range support exposed rooftop environments.

Simplified module-level installation

MC4 input and output connectors, with single-bolt assembly for quicker fitting.

Benefits
  • Supports module-level power optimisation in residential PV strings.
  • Helps reduce mismatch losses across modules in uneven roof conditions.
  • IP68 protection supports outdoor installation on rooftops.
  • High efficiency limits conversion losses at module level.
  • Compact form factor supports space-constrained roof layouts.
Technical Summary

Rated input DC power 650 W. Absolute maximum input voltage 80 Vdc. MPPT operating range 12.5–80 Vdc. Maximum module short-circuit current is 16.5 Adc with SolarEdge Home Hub or SolarEdge Nexis three-phase inverters, and 15 Adc with SolarEdge Home Wave inverters. Maximum output current 15 Adc and maximum output voltage 110 Vdc. Safety output voltage in standby 1 ± 0.1 Vdc. Maximum system voltage 1000 Vdc. Dimensions 129 x 165 x 45 mm, weight 790 g. Input and output connectors are MC4. Operating temperature range -40 to +85 °C, protection rating IP68.

Installation Notes

Use with compatible SolarEdge residential inverters only. Compatibility depends on inverter model, firmware version, and for some inverter families, production date. When connected to a SolarEdge Home Wave or Home Hub three-phase inverter, S650A Power Optimisers cannot be mixed with other power optimiser models on the same inverter. Maximum allowed system voltage is 1000 Vdc. Power derating applies above +70 °C. Input and output connectors are MC4. Input wire length is 0.1 m; output wire length is listed in the source as (+) 2.3 m and (-) 0.10 m, and should be verified before use.

Efficiency

Maximum efficiency is 99.5% and weighted efficiency is 98.6%. RoHS compliant.
