Feature: 1. Come with high conversion efficiency, quick start, load adaptability and stability 2. Good safety performance, the product has five protection functions of short circuit, overload, over-under-voltage, and over-temperature 3. Possess good anti-friction performance, and can resist squeezing or a certain external force impact 4. Output voltage 110/ automatic recognition, output voltage range from 95-140v/185-265V 5. The function of limiter(reverse current prevention function) is to automatically track the power of the electric load and connect to the grid to generate electricity. Automatically track how much electricity is generated by the home appliances to ensure there will not be too much electricity Specification: Item Type: Solar Inverter Product Certification: CE Circuit Topology: Half-bridge Frequency: 50Hz/60Hz Output Power: 1000W Inverter Efficiency: 99 (%) Load Regulation Rate: 99 (%) . Package List: 1 x Inverter1 x Power Cord1 x Limiter1 x User Manual Note: 1. 2 kinds of input voltage 22?65V DC and 45?90V DC, output voltage automatic recognition.2. If the electricity from the inverter is not enough for the electrical appliances in the home, it will be automatically supplemented from the city power for the electrical appliances. There is no need to worry about the insufficient power generated by the inverter and affect the use of electrical appliances in the home.
