Feature:1. High in Safety: The solar grid micro inverter can independently control each component in parallel, largely improving the safety.2. Reliable Using: Built in high accuracy instrument allows you to better check the working status of each component, very simple.3. Efficient Work: Maximum power point tracking can be achieved to maximize the overall output power.4. Better Control: Can be operated and monitored through WiFi or mobile APP, which greatly improves the overall working efficiency.5. Easy to Install: Can be installed directly behind the module or on a bracket for easy maintenance, very reliable and practical.Specification:Item Type: Solar Grid Micro InverterModel: GTB 300Maximum Input Power: 400WPeak Power Tracking Voltage: 22-48VMinimum and Maximum Startup Voltage: 20-50VMaximum DC Short Circuit: 20AMaximum Input Working Current: 12AAmbient Temperature Range: -40 To +60Waterproof Grade: IP65Communication Method: Wireless ModePower Transmission Mode: Reverse transmission, load priority.
