Feature: 1. [Heat Dissipation] The heat dissipation device of the inverter adopts a 24V DC cooling fan and an external aluminum heat dissipation base for efficient heat dissipation. 2. [High Brightness Digital Display] The operation of the inverter is user friendly, and its high bright red digital tube display can well avoid misoperation. 3. [Strong Safety] The inverter adopts ABS fire resistant and heat resistant plastic shell, and the terminals are fully enclosed to avoid the danger of electric shock. 4. [Exquisite Craftsmanship] The PCB board inside the inverter is treated with 3 proof paint, which has a simple structure and a low failure rate. 5. [Double Layer Board Design] The simplified double layer board design layout of the inverter greatly saves space and is easy to install. Specification: Item Type: Solar Photovoltaic Variable Frequency Drive Material: ABS, aluminum Model: 9600D 3T 00550D Input Voltage: DC400-700V Output Voltage: AC 3PH 0-380V 0-600Hz Rated Power: 5.5KW Rated Current: 13A Size: Approx. 126 x 160 x 170mm / 5 x 6.3 x 6.7in . Package List: 1 x Solar Photovoltaic Variable Frequency Drive1 x Instruction Note: 1. The default upper limit frequency of this solar photovoltaic inverter is 50HZ, and the reverse function is disabled by default. If you need to change it, please operate it correctly according to the instructions.2. Please try to meet the recommended voltage for the DC input voltage, otherwise the solar energy conversion rate will be reduced.3. The AC input and DC input switches cannot be closed at the same time, otherwise the inverter or solar panel will be damaged.4. Do not use the inverter with overload. For example, the power of the inverter is smaller than that of the motor, or the ordinary motor is running at more than 50HZ. The inverter on the other side will frequently skip the overload protection fault, and even if the machine is fried, the motor may overheat and burn out.5. Special inverter for solar energy, suitable for solar photovoltaic panel power generation to drive motor loads such as fans and pumps. The selection can be selected according to the motor voltage and power. If the water depth of the submersible pump exceeds 30 meters, it is recommended to enlarge one or 2 stages of optional inverter, and add a reactor between the inverter and the water pump. Otherwise, the service life of the inverter will be reduced.6. Regarding how to connect the solar panels, such as a 220V motor, the total voltage of the solar panels connected in series must meet 200V to 400V. 380V motor, the total voltage in series should meet 400V to 700V. The power is that the total power of several groups of solar panels connected in parallel is more than 1.2 times larger than the power of the inverter.
