Low Frequency Solar Inverter 1-8kw
Product Introduction
1. Pure sine wave output, suitable for various loads;
2. Dual CPU management, intelligent control, modular composition;
3. The solar energy priority and mains power priority modes can be set, and the application is flexible;
4. LED display can intuitively display all the operating parameters of the machine, and the operating status is clear at a glance;
5. High conversion efficiency, the conversion efficiency is between 87% and 98%; low idle consumption, the loss is between 1W and 6W in the sleep state; it is the best choice of solar inverter for solar/wind power generation systems;
6. Super load resistance, such as driving water pumps, air conditioners, refrigerators, etc.; rated power 1KW solar inverter can drive 1P air conditioners, rated power 2KW solar inverters can drive 2P air conditioners, 3KW solar inverters can drive 3P air conditioners, etc.; according to this feature This inverter can be defined as a power type low frequency solar inverter;
Perfect protection function: low voltage, high voltage, high temperature, short circuit, overload protection, etc..
Way of Working
1. Pure reverse type
The direct current generated by the solar panel passes through the external charge and discharge controller, which usually charges the battery. When power is needed, the solar inverter converts the direct current of the battery into a stable alternating current for the load to use;
2. Mains complementary type
City power main type:
The direct current generated by the solar power generation panel charges the battery through an external charge and discharge controller; when the mains power is cut off or abnormal, the solar battery converts the direct current of the battery into a stable alternating current through the solar inverter for use by the load; this The conversion is completely automatic; when the mains power returns to normal, it will immediately switch to the mains power supply;
Solar main supply type:
The direct current generated by the solar power generation panel is charged to the battery through an external charge and discharge controller. Switch to mains power supply.
