Feature: 1. The grid tie inverter adopts IP65 waterproof streamline designs, which can effectively prevent the erosion of the surface by rainwater. 2. Full digital control, reverse power transmission, intelligent monitoring and management, low cost of operation and maintenance. 3. In cloudy days, the output current of the solar cell is extremely small, and the inverter automatically turns on the 6‑level power search function to achieve continuous, stable and efficient power output at low power, which greatly improves the generation capacity of the generation system all day. 4. The precise dynamic differential pressure MPPT function and APL function are adopted to automatically adjust the power of solar panels to the maximum output. 5. The solar panels need to be directly connected to the grid‑connected inverter, and there is no need to connect batteries Specification: Condition: Brand New Item Type: Micro Inverter Material: Aluminum Alloy Color: Blue Frequency: 50/60Hz Maximum DC Input Voltage: 54VDC Maximum power tracking voltage: 22‑45V Operating Voltage Range: 17‑50V Maximum DC Short Circuit Current: 40A Maximum Input Operating Current: 27.2A Heat Dissipation: Self‑cooling Communication Mode: Power line carrier Power Transmission Mode: Reverse transmission, load first use. Package List: 1 x Micro Inverter1 x Manual 1 x Mounting Bag (2pcs Screw, 2pcs Nut, 2pcs Gasket)1 x AC Connection Cable1 x Connector Cable Note: Please note that the new type and old type of this product will be sent randomly, and make sure you will not mind before ordering.1. The product can not work for a long time in a high power state, the higher the power, the faster the heat.2. The shell temperature reaches 65 degrees will enter the high temperature protection state, you can open the case, with a fan against the machine on the circuit board heat sink (aluminum block) and transformer blowing, pay attention to safety, do not touch. You can solve the problem of over‑temperature protection.3. Pay attention to the smooth airflow, need to be away from objects susceptible to high temperatures.4. Inverter input and output conversion efficiency of 80%, the greater the input power, the greater the output power, the highest output power is 600W.
