  The label in the picture is the power parameters of machine motor. I was task to size a solar power system that can run 10 of this machine simultaneously for 10 hours. To size these system, Let's recap the given parameters and calculate the unknown. From the label information provided on your clutch motor, here are the summarized points regarding its rated running power and other electrical characteristics: 1. Rated Running Power:    - The motor is rated at 1/3 horsepower (HP). To convert this into watts (since 1 HP equals approximately 746 watts):    Power (W) = 1/3 x 746= 249watts. 2. Rated Voltage and Current:    - The motor operates at a voltage of 220 volts    - The normal operating current is between 1.71 to 2.16 amperes. 3. Surge Multiplier Factor:    - The label does not specify the inrush (surge) current explicitly, only the typical running and potential starting currents. The inrush current for motors can typically be se...

 Parameters Recap from our previous sizing steps 1. Daily Energy Consumption: 20.75 kWh 2. Total Peak Power: 3430 W 3. Days of Autonomy: 2 days 4. Solar Hour: 4 hours 5. Calculated Solar Array Value: 6.48 kW 6. Number of Solar Modules: 22 pieces of 300W modules 7. Battery Bank Size: Approximately 960.65 Ah at 48V (with 90% DOD) "DOD" stands for (Depth of Discharge) 8. Inverter Sizing: 5KVA inverter is ideal for the system 9. Charge Controller Size: 170A (rounded up from 168.75A with a safety margin of 25%) Number of Charge Controllers Needed: 2 (assuming 100A controllers are used) 10. System Cable Sizing?
