Maximise Solar Performance on Any Roof
The SolarEdge Home Short String Inverter is the ideal solution for small-scale residential solar installations with challenging roof designs. It supports significantly shorter strings, allowing for maximum energy harvest even on multi-faceted or shaded roofs.
Combined with SolarEdge Power Optimizers, each module performs at its peak, reducing mismatch losses and enabling advanced module-level monitoring for greater system visibility and reliability.
Unmatched Efficiency and Reliability
With a maximum efficiency of up to 97.8% and European weighted efficiency up to 96.3%, this inverter converts more solar energy into usable electricity. Homeowners benefit from lower energy bills and reduced grid reliance.
Future-Ready Integration and Smart Control
As the heart of the SolarEdge Home ecosystem, this inverter seamlessly integrates with:
- SolarEdge Home Battery (400V) in selected regions for energy storage
- Smart energy devices for home load control, export limitation, and enhanced energy management
- SolarEdge EV chargers for future-proof electric vehicle readiness
Advanced Safety You Can Trust
The inverter’s built-in touch-safe DC voltage feature reduces electrical risks during maintenance or emergencies. Additional protections include ground-fault detection, reverse-polarity protection, and compliance with strict international safety standards (IEC 62109, EN 50549).
Simple Installation and Flexible Design
Installers benefit from a lightweight 24.5 kg design, integrated mounting brackets, and simple plug-and-play connections. The SetApp mobile app ensures fast commissioning via local Wi-Fi, and the IP65 rating supports indoor and outdoor installations.
Ideal for Homes and Small Businesses
Perfect for homeowners with 3–5 kW systems on complex roofs, or small businesses seeking reliable, quiet, three-phase inverter solutions. It’s also ideal for users planning future battery or EV charger additions.
