Installation & Support
Rated for quick installation with remote setup options and a 5-year standard warranty, upgradable to 10 years with registration.
Designed for slightly higher solar demands, this model brings the same smart features with a boost in output capacity:
Enhanced Power & Oversizing
Provides 3,680 W of output, while still supporting 200% DC oversizing—perfect for slightly larger or future‑proof systems.
Robust MPPT Performance
Dual-track MPPT with 40–560 V range and 50 V start-up, maintaining high performance across shading or mismatch situations.
Consistent Build Quality
Shares the same IP66, fan‑less design and lightweight build (~11 kg) as the 3.0 kW model, ensuring silent and resilient operation.
Smart Functionality
Integration of WiFi, AFCI, SPD protection, and export control with data diagnostics keeps your system connected and secure.
For high-demand or larger-scale installations, this model combines power and intelligence in one sleek package:
High Output & Oversizing Capability
Delivers 6,000 W output — and supports up to 200% oversizing, so your system can scale up without early limitations.
Technical Excellence
Dual MPPTs cover 40–560 V with a low 50 V start-up. The inverter hits up to 97.8–98% efficiency, ensuring top-tier energy conversion.
Sturdy & Compact
ICer IP66‑rated housing, weighs 11–15 kg (depending on source), and the compact 341.5 × 430 × 143 mm or 404 × 274 × 146 mm form factor fits most installations.
Advanced Monitoring & Protection
Seamless WiFi V3 connectivity, SPD protection, AFCI support, and export limitation via meter provide exceptional safety and control.
Smart Integration & Warranty
Supports EV chargers, heat pumps, parallel operation, and cloud maintenance. Comes with 5 years warranty, extendable free to 10 years.
