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.
