SolarEdge Technology Overview

A short comparison of the three inverter topologies - string inverters, microinverters and SolarEdge DC optimized inverters. Learn how the SolarEdge solution combines the best of both worlds

More Energy Output

Module-level MPPT eliminates losses to maximize power independently from each individual module regardless of module brand and lifetime. Underperforming modules do not affect the production of the whole string offering more energy production from the PV system.

Constrained flexible design to maximize space utilization with minimum design time:

Typical String Inverter SolarEdge
Limited string length 26-60 modules per string (up to 12.75kW)
Must match string lengths per MPP tracker Uneven strings can work in parallel
Shaded modules affect the entire string Only shaded modules are effected
Cannot mix different types of modules Any module size or type can be used
Locked in to same orientation/tilt per MPP tracker Any orientation/tilt

Reduced O&M cost

Free module-level performance monitoring & remote maintenance for system lifetime lead to more effective and efficient O&M by decreasing trips to sites, reducing the amount of time spent on site, and increasing system uptime.

SolarEdge’s PV Asset management features:

  • Full visibility of your system's technical and financial performance, including interactive charts and site layout 
  • Visualization of PV production, building consumption, and self-consumption
  • Data presentation at the module-level, string-level and system level 
  • Comprehensive site-level and fleet-level reporting and analysis tools with an option to schedule automatic reports and export reports
  • Easy access from a computer, smartphone, or tablet
  • Effective fleet management and improved O&M capabilities:
    1. Automatic alerts on system issues
    2. Remote troubleshooting and access to real-time system data and guided root-cause fault analysis
    3. High resolution data, including historical and aggregated views with comparative analysis diagnostics

Lower BoS Cost

With Up to 34% overall BoS cost-saving (less string, wiring, combiner boxes, fuses, etc), SolarEdge enables longer strings generating more modules each strings with up to 40 panels each string which amount is two times higher than traditional inverter).

Table comparison between Traditional Inverter & SolarEdge in regards to BoS cost

  Traditional Inverter SolarEdge
DC cable 1*6mm (m) 9,469 3,754
MC4 connectors (pairs) 160 90
SolarEdge 3 strings DC box - 15
Traditional Inverter 10 strings DC box 8 -
Communicztion gateway 1 -
Cost 100% 66%
Savings of ~0.75c/w

Future Compatibility & Warranty

SolarEdge offers distinctive satisfactory features to eventually decrease any future costs, such as:

  • Longer inverter warranty with up to 40% lower-cost inverter replacement than traditional inverter
  • Free lifetime monitoring cloud system
  • Greater energy expansion for individual module even in the same string
  • Resistant to ammonia corrosion in agricultural areas

Enhanced Safety Solution - SafeDCTM

Superior Safety

SolarEdge provides superior safety which is able to minimize electrocution risk compare to traditional string and central inverters. Traditional inverter only terminates the electric current flow, while electrocution risk still remains as long as the sun is shining.

SolarEdge SafeDC™

SolarEdge SafeDC™ offers a safety features to automatically switch into safety mode to 1VDC output on each module. It can ensure the installers, maintenance personnel and firefighters during the maintenance, installation and high temperature of module (above 85℃).

ARC Fault Detection and Interruption

Passing UL1699B standard, SolarEdge inverters are designed to mitigate effect of some arcing faults that may lead to risk of fire.

Quick Payback Time

More modules installation, more generated energy, lower O&M cost, lower BoS and superior safety will ultimately deliver shorter payback period with the best energy harvest at all time.
