In theory this can be done.
It just requires more solar panels and batteries, and the power of the sine wave inverter also needs to be large enough.
If we consider refrigeration first, 1.5 horsepower is calculated based on a power consumption of 1,300 W. Three units running 24 hours a day consume 93.6 kilowatt hours of 'electricity. To make the calculation easier, use 100 degrees.
A single solar panel is 1.6 meters long and 1 meter wide, with a power of about 300 W. If there are only 8 hours of sunshine per day, it must generate an average power of 12.5 kW. the maximum power is 17.8 kW. According to this calculation, 60 of these solar panels are needed.
At the same time, battery storage is necessary. It must store 67 kilowatt hours of electricity every day. If it is a 12V100Ah battery, 56 batteries are needed.
This is only calculatede for the current day. If it can be used in cloudy weather (the next day is sunny), then it should be doubled (the battery should be increased more than once). If it can be used for 2 consecutive cloudy days (the third day). is sunny), then it should be doubled (the battery should be increased more than 1 time).
How many electrical appliances can four 535 solar panels drive?
Air conditioners are divided into fixed frequency and variable frequency. The power consumed by a 1.5 HP fixed frequency air conditioner during cooling is . about 1100W, and the 1.5HP variable frequency air conditioner is stable. The operating power is about 500-700W. Fixed frequency works intermittently, while the overall average power of variable frequency and fixed frequency is not much different. For convenience, 600w is used as the standard for calculation.
FirstBasically, the scenario assumes that you run the air conditioning 24 hours a day.
Set the power to 600 W and consume 14.4 kilowatt hours of electricity in 24 hours. The solar panel generates 5 kilowatt hours per day on sunny days. To use the air conditioner 24 hours a day, you need 3 kW solar panels and batteries capable of storing 10 kilowatt hours of electricity.
Considering that the efficiency of commercially available power frequency inverters is generally around 75%, it is rare to purchase a power frequency inverter with an efficiency of 90%, therefore batteries and solar energy. A margin of 25% must be left.
Also, it's not as simple as a 1.1 kW inverter can drive a 1.1 kW air conditioner. Since the compression motor is a typical inductive load, the instantaneous starting power is. essentially, the pRated power is about 5 times the power, so the inverter should be more than 5 times the rated power of the air conditioner to start the air conditioner smoothly. Therefore, the inverter must be greater than 6 kW. The inverter air conditioner is much smaller and the inverter can be smaller accordingly. However, considering inductive loads such as refrigerators and washing machines, it is recommended to choose a large inverter rather than a small one.
Solar panels should not be directly connected to the air conditioner. The power supply is unstable and the air conditioner is easily damaged. There must be a large capacity battery to store electricity. power, then reverse the voltage of the air conditioner.
The biggest problem is that there can't be clouds in the sky blocking the sun. If a white cloud is floating above your house, you should turn off your air conditionerur.machine! Anyone who has used a solar water heater knows that it produces boiling water in summer and hot water in winter.
Regardless of the size of the panel solar, it cannot be used. for air conditioning, because the electricity produced cannot be stored. On sunny days, electricity is only produced for 4 hours per day and there is no electricity the rest of the time.
Lights, air conditioners, etc. Four 535 solar panels can produce 5 kWh of electricity based on efficient lighting for 5 hours a day, or 5 kilowatt hours of electricity, which can power light bulbs, air conditioners, refrigerators and other appliances. Solar panels are devices that absorb sunlight and convert solar radiation energy directly or indirectly into electrical energy by photoelectric effect or photochemical effect. The main material of most solar panels is"silicon", but due to the high production cost, it cannot be widely used. and commonly.
