The Inverter is a Critical Investment
Inverters account for only 10% of system costs but they influence:
30%of Project
Costs
20%of O&M

MPPT per module:̶ Each module produces maximum power independently of other
modules in the string̶ Underperforming modules do not affect the production of the
whole string

BoS Cost Savings
SolarEdge systemTraditional system
Up to 50% reduction in BoS costUp to 60
modules per string
Fewer strings
Less wiring, combiner boxes, fuses, etc.
Less onsite self-crimping at string end
Reduced risk of failure & fire

Fewer Strings = Less Wiring
Traditional string inverter: 10.4 m/kW DCSolarEdge system: 2.3 m/kW DCIn megawatt scale systems, the difference can amount to hundreds of thousands of dollars

Protecting System Owner Investment
When AC power shuts off or inverter disconnects:̶ With traditional inverter, PV wires remain energized with dangerously high
voltage̶ With SolarEdge, PV wires are automatically de-energized to safe 1 Vdc per
moduleThe SolarEdge Advantage̶ Provides superior safety for installers, electricians, and fire fighters̶ Best suited for future insurance requirements

Asset Management
Protect your asset with full visibility into system performance & remote troubleshooting for reduced O&M costs̶ Monitoring at the module level – free for lifetime̶ Fault detection pinpointed on a virtual site map̶ Automatic alerts on system issues
| 19©2015 SolarEdge
Increased Uptime: Real-time Alerts
Alerts for modules & invertersCustom settings available ̶ Time of day ̶ Offset from sunrise and sunset̶ % deviation from average

Increased Uptime: Remote PID Detection
Strong degradation of power in the modules closest to inverter’s negative poleIf PID is suspected, technicians must climb on roof, disconnect modules, and measure their output voltageUsing SolarEdge monitoring portal, PID problems are quickly detected
Analyze degradation of power in modules via portal
Module voltages measured remotely, no need to send technicians to the roof
