Feature:1. Efficient Heat Dissipation: The variable frequency inverter adopts 24V DC cooling fan and external aluminum heat dissipation base, can efficient heat dissipation2. Digital Tube Display: The photovoltaic inverter screen is clearly displayed by a bright red digital tube for easy viewing3. Double Layer Board Design: The VFD converter adopts double layer board design, the PCB board is treated with three proof paint, with simple structure, has low failure rate4. Anti Electric Shock: The terminal is fully surrounded by design to avoid the danger of electric shock, which is safe to use5. Heat Resistant Material: The outer casing of the inverter is made of ABS fire resistant and heat resistant plastic material, has long last durabilitySpecification:Item Type: Variable Frequency InverterMaterial: ABS and AluminumModel: 9600D-3T-00400DRated Power: 4.0KWRated Current: 8.5ASize: Approx.126x160x170mm/5x6.3x6.7in.Package List:1 xVariable Frequency Inverter1 x ManualNote:1. There is a slight error in the size due to manual measurement.2. The default upper limit frequency of this solar photovoltaic inverter is 50HZ, and the reverse function is disabled by default. If you want to change it, please operate correctly according to the instructions.3. Please try to meet the recommended voltage for the DC input voltage, otherwise the solar energy conversion rate will be reduced.4. The AC input and DC input switches cannot be closed at the same time, otherwise the inverter or solar panel will be damaged.5. 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, in these situation, the inverter will frequently skip the overload protection fault, and even fry the machine, the motor may be overheated and burn out.6. Special inverter for solar energy, suitable for solar photovoltaic panel power generation to drive motor loads such as fans and pumps. The type 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 two 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.7. Regarding how to connect the solar panels, such as a motor, the total voltage of the solar panels connected in series must meet 200V400V. For 380V motor, the total voltage in series should meet 400V700V. 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.
