1、The built-in WIFI monitoring module can set the WIFI Internet of Things monitoring mode, which can effectively improve the efficiency. 2、Built-in MPPT tracking function, the accuracy is as high as 99.9%, control different output power, effectively track and collect sunlight. 3、With over‑voltage and under‑voltage, over‑frequency and under‑frequency, over‑temperature protection functions, grid fault detection and protection functions. 4、Support one‑key operation, the power, power, efficiency, and income can be seen at a glance. 5、The micro inverter can be installed directly behind the module or on the bracket, which is easy to maintain. 1 x Micro Inverter1 x AC Connection Line1 x Installation Package1 x User Manual Item Type: Micro InverterModel: GTB-1200Circuit Topology: Push-pullMaximum Input Power: 1200WPeak Power Tracking Voltage: 22-50VStarting Voltage: 22-55VMaximum DC Short-circuit Current: 60AMaximum Input Working Current: 54.5APeak Output Power: 1200WRated Output Power: 1200WRated Output Current: 120V: 10A; 230V: 5.2ARated Voltage Range: 120V: 90-130VAC; 230V: 180-240VACRated Frequency Range: 48-51Hz/58-61HzPower Factor: 99%Circuit Connection Number Per String: 120V: 3 units (single-phase); 230V: 5 units (single-phase)Static MPPT Efficiency: 99.5%Maximum Output Efficiency: 97%Power Loss at Night: 1WTotal Harmonic Distortion: 5%Inverter Efficiency: 90%Voltage Regulation Rate: 90%How to Use: 1. Download "smart home" or direct scan code to the right qr code and install the monitoring system app(the multi-language for ios system); 2. Click and create the new user to register the account 3. Please enter the password and confirm the password when you enter the password in the family 4. After entering the wi-fi password, the inverter will remain in the normal working green light state, and the system will make a paired connection (as shown in fiqure 5 and 6).
