Huawei Three-phase Inverter 50kW SUN2000L-50KTL-M3
Modelo: SUN2000L-50KTL-M3- Sku: HUAWINV044
- Vendor: Huawei
Specifications
Product description
The Huawei SUN2000L-50KTL-M3 is a 50 kW three-phase solar inverter designed for commercial and industrial photovoltaic plants requiring maximum output, safety, and operational control. It incorporates 4 MPPT with 8 inputs to optimize performance on rooftops with different orientations or partial shading, achieving a maximum efficiency of 98.5%. Its IP66 enclosure, active arc protection (AFCI), and PID recovery function ensure long-term reliability even in demanding environments.
Main features
- Nominal AC power: 50 kW; maximum apparent power: 55 kVA.
- PV architecture with 4 MPPT and 8 strings for maximum design flexibility.
- PV voltage: max. Voc 1,100 V; MPPT range 200–1,000 V; nominal 600 V.
- Current per MPPT: max. 30 A with two strings / 20 A with one string; Isc max. per MPPT 40 A.
- Max. efficiency 98.5% and European efficiency 98.0% for higher annual yield.
- Advanced safety: AFCI, anti-islanding, type II SPD on DC and AC, DC disconnector, insulation fault detection, and RCMU.
- Integrated communications: LED, Bluetooth + App, RS485; expandable with Smart Dongle WLAN/Ethernet or 4G.
- “Smart air” cooling and night-time consumption ≤ 5.5 W to reduce OPEX.
Advantages or benefits
- More kWh per area: 4 independent MPPT trackers reduce losses due to mismatches and shading, and allow for long strings with high-power modules.
- Professional safety: AI-based arc detection, integrated surge arresters, and DC disconnection protect the installation and minimize risks.
- Optimized maintenance: string-level monitoring and remote diagnostics with FusionSolar make it easier to locate issues and reduce downtime.
- Project flexibility: 400/480 Vac output and wide thermal range for outdoor use without additional panels.
- Long-term reliability: integrated PID recovery to maintain module performance and increase energy generated throughout the entire service life.
Purpose or applications
The SUN2000L-50KTL-M3 is ideal for three-phase self-consumption and grid-tied plants in logistics warehouses, agro-industry, shopping centers, hotels, energy communities, and small ground-mounted parks. Its transformerless topology and ability to operate with high currents per MPPT simplify electrical design, reduce cabling, and improve CAPEX.
