Feature: 1. Solar Inverter: The input voltage is DC200‑400V, and the output voltage is AC 3PH 0‑ 0‑650Hz, very efficient. 2. Easy Operation: Highlight red digital tube display enables clear view for easy manual operation with small error. 3. Safe for Works: Double layer board design along with simple structure ensures low failure rate for safer working. 4. Good Materials: ABS shell is very sturdy with fire, and the fully surrounded terminals can avoid electric shock. 5. Quick Cooling: Designed to have DC 24V cooling fan and external aluminium cooling base for quick heat dissipation. Specification: Item Type: Variable Frequency Drive Material: ABS + Aluminium Model: 9600D-1T-00150D Rated Power: 1.5KW Rated Current: 7A Dimension: Approx. 82 x 145 x 155mm / 3.23 x 5.71 x 6.1in. Package List: 1 x Variable Frequency Drive1 x User Manual Note: 1. Please try to meet the recommended voltage for the DC input voltage, otherwise the solar energy conversion rate will be reduced. 2. The AC input and DC input switches cannot be closed at the same time, otherwise the inverter or solar panel will be damaged. 3. 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, otherwise the inverter will frequently skip the overload protection fault, and even blow the machine, the motor may be overheated and burn out. 4. Special inverter for solar energy, suitable for solar photovoltaic panel power generation to drive motor loads such as fans and pumps. Select 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. 5. Regarding how to connect the solar panels, such as a motor, the total voltage of the solar panels connected in series must meet 200V‑400V. 380V motor, the total voltage in series should meet 400V‑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.
