Description
The Growatt MID 20K TL3-X is an advanced 20kW three-phase on-grid solar inverter designed to convert direct current (DC) generated by photovoltaic panels into reliable, grid-synchronized three-phase alternating current (AC).
Engineered for commercial rooftop owners, medium-scale industrial plants, corporate offices, and institutional installations across Bangladesh, this transformerless inverter features dual MPPT tracking to maximize energy output across multi-oriented array setups. With rising grid electricity tariffs in Bangladesh, deploying the Growatt MID 20K TL3-X enables enterprises to lower operational costs through Net Metering while maximizing self-consumption of clean solar energy.
Key Features
- Dual MPPT Architecture: Includes 2 independent Maximum Power Point Tracking (MPPT) channels with 2 string inputs per tracker (4 total strings) for optimized array performance.
- Touch-Enabled OLED Display: Equipped with a durable QLED/OLED display interface with a touch key for easy, touch-free local parameter monitoring.
- Integrated Type II AC & DC Surge Protection: Built-in Type II Surge Protection Devices (SPD) safeguard system electronics against atmospheric lightning strikes and utility grid surges.
- Smart I-V Curve Scan & Diagnostics: Built-in diagnostic tools enable intelligent string-level troubleshooting to quickly locate module faults and shading issues.
- IP65 Rated Enclosure: Built with a high-strength, fireproof polycarbonate cover designed for outdoor deployment against heavy rain, dust, and humidity.
Technical Advantages
- High Conversion Efficiency: Achieves a maximum efficiency of 98.75% (European efficiency of 98.6%) to minimize internal power losses during conversion.
- Compact & Lightweight Engineering: Weighs only 23 kg, making installation significantly easier and faster for site technicians compared to bulky traditional commercial inverters.
- Comprehensive Electrical Protection: Features DC reverse polarity protection, AC short-circuit protection, ground-fault monitoring, insulation resistance tracking, and optional Arc Fault Circuit Interrupter (AFCI).
- Grid Support & Stabilization: Offers an adjustable power factor (0.8 leading to 0.8 lagging) and low total harmonic distortion (THDi < 3%) to preserve factory power quality.
- Easy Maintenance & Remote Tracking: Supports plug-and-play monitoring accessories (Wi-Fi-X, LAN-X, or 4G) for real-time fleet management via Growatt’s ShinePhone app.
Applications
- Residential: Large multi-story residential estates and luxury private villas requiring 3-phase power.
- Commercial: Retail shopping centers, commercial office buildings, hospitals, and educational campuses.
- Industrial: Garment factories, light manufacturing units, agro-processing plants, and cold storage facilities.
- Factory: Rooftop PV system retrofits aimed at lowering daytime peak load expenses.
- Office: Enterprise corporate offices and administrative centers utilizing net metering.
- Project Installation: Mid-tier commercial grid-tied IPP and rooftop solar projects across urban and rural zones in Bangladesh.
