🔍 Key Technical Features
1️⃣ High Conversion Efficiency – Up to 99.03%
Huawei’s 185KTL-H1 and 330KTL-H1 achieve world-class efficiency levels, reducing losses across the power conversion chain. This directly contributes to a lower LCOE for utility developers.
2️⃣ Multiple MPPTs with Advanced String-Level Management
The SUN2000-185KTL-H1 offers 9 MPPTs while the 330KTL-H1 offers 6 MPPTs, enabling flexible string configurations and superior yield even in installations with uneven irradiation or terrain.
3️⃣ AI-Powered Arc Fault Detection (AFCI)
Integrated AI-based AFCI detects arc faults within milliseconds, drastically reducing fire risk across megawatt-scale DC arrays.
4️⃣ 1500V Architecture
Both inverters are designed for 1500V DC input, which:
-
Reduces wiring costs
-
Lowers system losses
-
Improves BOS (Balance of System) cost-efficiency
5️⃣ Intelligent Cooling for Harsh Climates
Their smart air-cooling system, with internal thermal sensors and self-adjusting fan speeds, ensures peak performance even in hot Kenyan regions like Turkana, Isiolo, or Taita Taveta.
6️⃣ Grid Code Compliance & Support for Kenyan Utilities
Huawei’s utility-scale inverters are certified to meet international and local grid codes (e.g., KPLC and EPRA standards), with features like:
-
Reactive power support (Q-V and F-W control)
-
Zero-export mode
-
Nighttime SVG functionality
