Huawei FusionSolar Inverter 12kW 3-Phase 2-MPPT with DC Disconnector, RS485, WLAN, SPD AC/DC Type II, Battery Interface, Asymmetrical AC Output, 3-Phase Backup Ready

The Huawei FusionSolar inverter is a high-performance 3-phase hybrid inverter designed for residential and commercial solar installations. With 12kW rated AC output power (13.2 kVA) and dual MPPT trackers, it maximizes energy harvest from photovoltaic arrays. The inverter features integrated communication interfaces (RS485 and WLAN), a built-in DC disconnector, and surge protection for both AC and DC sides (Type II). It supports battery charging with Huawei LUNA2000 series batteries and offers asymmetrical AC output. The 3-phase backup function is available with the optional Smart Guard device, ensuring uninterrupted power supply during grid outages.

Advantages

High efficiency (max 98.6%) and European efficiency (97.9%) ensure optimal energy conversion. The natural convection cooling system operates silently and requires no maintenance. With IP65 protection rating, the inverter is suitable for outdoor installation. The integrated DC disconnector enhances safety during maintenance. The inverter is compatible with Huawei's smart energy management ecosystem, allowing remote monitoring and control via the FusionSolar app.
