Feature: 1. INPUT AND OUTPUT: Solar photovoltaic inverter, input voltage is DC200‑400V, output voltage is AC 3PH 0‑, efficient and durable. 2. GOOD COOLING: Using 24V DC cooling fan, external aluminum cooling base, efficient heat dissipation, to ensure long term work. 3. STABLE STRUCTURE: The inverter is double layer board design, and the PCB board is treated with 3 proof paint, so the failure rate is low. 4. HUMANIZED DESIGN: Adopts humanized operation, with bright red digital tube display, which is convenient for reading and avoids misoperation. 5. DURABLE MATERIAL: ABS plastic shell is fire and heat resistant, and the terminal is fully enclosed to avoid the danger of electric shock. Specification: Item Type: Solar Photovoltaic Inverter Material: ABS, Aluminum Model: 9600D-1T-00400D Rated Power: 4.0KW Rated Current: 16A Size: Approx. 126 x 160 x 170mm / 5 x 6.3 x 6.7in (manual measurement, the parameters have certain errors) . Package List: 1 x Inverter1 x User Manual Note: 1. The default upper limit frequency of this solar photovoltaic inverter is 50HZ, and the reverse function is turned off by default. If you need to change it, please operate it correctly according to the user manual.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. Otherwise, the inverter will frequently skip the overload protection fault, and even the motor may be damaged. It may burn out due to overheating.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 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.6. 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.
