🧠 Intelligent Design Features
🔋 Smart MPPT Management for Complex Roofs
Each inverter offers multiple MPPTs, enabling precise optimization across diverse roof pitches or shading conditions—common in Kenyan school buildings or factories with obstructions.
🧠 AI-Based Arc Fault Detection (AFCI)
Huawei’s built-in AI-enhanced AFCI proactively detects and mitigates DC arcs, a leading cause of rooftop fire hazards in C&I installations.
📲 FusionSolar Smart Monitoring
Each inverter supports the FusionSolar Portal and App, offering real-time monitoring of every string, performance alerts, remote updates, and energy dashboards.
⚙️ Integrated PID Recovery
Protect PV module lifespan with built-in PID (Potential Induced Degradation) recovery, restoring module voltage overnight for enhanced durability.
💨 Intelligent Cooling
With active fan-assisted thermal management, these inverters maintain consistent performance even under high Kenyan ambient temperatures like in Kisumu or Mombasa.
