Key Features of Growatt MID 25-40KTL3-X

1. High Efficiency & Yield
Maximum Efficiency: Up to 98.8%, ensuring minimal energy loss.
Multi-MPPT Design: Equipped with 3 or 4 MPPTs (depending on the model) to reduce string mismatch losses and handle complex roof orientations.
1.5 DC/AC Ratio: Supports oversizing of the DC array to maximize AC output during low-light conditions.

2. Safety & Reliability
AFCI Protection: Integrated Type II DC and AC Surge Protection Devices (SPD) and optional Arc Fault Circuit Interrupter (AFCI) to prevent fire hazards.
IP65 Protection: Robust casing suitable for harsh outdoor environments, protecting against dust and high-pressure water jets.

Natural Cooling: Optimized thermal design ensures stable operation without the noise or maintenance issues of external fans.

3. Intelligent Management
Smart O&M: Supports online smart service and remote firmware upgrades, reducing on-site maintenance costs.
24/7 Monitoring: Compatible with WiFi, GPRS, and 4G communication for real-time data tracking via the Growatt ShineServer and ShinePhone app.
Export Limitation: Built-in functionality to manage power export to the grid, complying with local utility requirements.

4. User-Friendly Design
Compact & Lightweight: Approximately 40% lighter than traditional inverters in the same power class, making installation faster and easier.
OLED Display & Touch Button: Modern interface for easy on-site configuration and data checking.
