How should we calculate the total power of the load? And how should we to choose an inverter?

＃***Experiments show that power equals the product of voltage U and current I, i.e., P = (____). When applying this formula, all quantities must be in SI units: U is in V, I is in A, and P is in W.***＃

1.Picture 2 is a refrigerator : the total power is about 215.6W(P=220V*0.98A)，and the Max power is 431.2W(.

2. Picture 3 is a AC: the cooling capacity is approximately 955W, and his heating capacity is approximately 1100W, and the Maximum power is 2200W. (You can also calculate the total power of the appliance by multiplying the current by the voltage!。

So the operating power of these household appliances is approximately 1315.6 W. The maximum starting power is 2,631.2W.

******Please note that the maximum power is the starting power of all electronic appliances when they are turned on. This starting power usually lasts for 20 seconds, after which the electronic appliance will return to its normal operating power!******

*****The starting power of our pure sine wave inverter is also 2 or 3 times the normal operating power!******

Therefore, our company's 3.5KW or 4.2KW pure sine inverters can drive these appliances!

I am sharing the relationship between inverters and loads today.
1. the higher the power of a pure sine inverter, the greater the total power that the inverter can drive for the load.
2.The voltage of household appliances is usually 110V or 220V, And more is use single-phase；for the industry voltage is usually 380V, 410V. or +-800V，more is use three-phase.
3.Our pure sine wave inverter can automatically adjust the voltage and filter out unstable voltage before transmitting it to all appliances. Cheap and low-quality modified wave inverters cannot automatically adjust the voltage. The most obvious example is when you find that the brightness of your home's lights is fluctuating for a long time, it means that you are using a modified wave inverter.
4.Please remember that if you are using a high-power inverter and the total power of the load you are driving is high, your battery will be drained very quickly. Don't assume there's something wrong with your battery;If you are using a high-power inverter but the total power of the load you are driving is low, then the battery will consume power slowly. Don't assume that because you bought a high-quality inverter,so the battery will consume power slowly.

I am sharing what the relationship with inverter and solar panel.

1. Solar panel voltage is DC, but all loads are 220V, 110V. 380V or industry voltage is more than 400V,so the inverter needs to convert DC voltage to AC voltage, and then these AC voltages can enable the load to operate normally.

2. Our high-quality pure sine wave inverters feature automatic power-off protection to prevent short circuits, overcharging, overvoltage, overload, and over-discharge. Therefore, when the operating voltage of the solar panels enters the power station system and the voltage is unstable, our inverter will automatically adjust the voltage to a range that the load can stably handle, or the inverter will sound an alarm indicating that the solar panel voltage is too high. Then, the inverter will stop working, effectively isolating the faulty voltage from entering the power generation system and preventing it from contacting the load.（This is what I've always said about an inverter being like a faucet, but the key is that this faucet also has a filter function.)

I am sharing the relationship between batteries and inverters today.
1. Voltage Relationship：
1). From the solar panel to battery is DC voltage, but all load is 220V. 110V or 380V or industry voltage is 400V more than。
so the inverter needs to help the battery convert the voltage, converting DC voltage to AC voltage, and then allowing the load to operate normally!
2).The government's voltage is 220V. When there is insufficient sunlight, and the government can supply electricity, the inverter needs to convert the government's voltage to DC voltage, and then the battery can store the government's electricity.
3).If your country has a subsidy policy for private power generation systems, you can sell any unused electricity from your battery to your country's government power generation system every day. Your country's government power system uses 220V AC, while the battery uses DC. Therefore, the inverter needs to convert the DC voltage from the battery back to AC voltage before selling the electricity to the government power system.
2.Our inverters have automatic power-off protection against short circuits, overcharging, excessive high voltage, excessive load, and over-discharging. These protection measures ensure that the battery is not damaged when a circuit fault occurs.
3.When both the inverter's output power and the load are excessively high at same time, the battery will discharge quickly; conversely, it will discharge slowly. Therefore, remember that it's not a large inverter that consumes power quickly, but rather a large load that consumes power quickly. However, the load's power requires the inverter to authorize its operation; therefore, the larger the inverter's power rating, the wider and load higher the range of loads it can authorize.

Let me elaborate on the working principle of solar panel and what's the different of the original solar energy and solar panel energy.
1.The working principle of solar panel is that the heat generated when sunlight shines on solar panels is converted into electricity. However, the amount of heat generated varies with the weather and the intensity of sunlight each day. For example, on cloudy or rainy days, the solar energy is weaker in the morning and evening, resulting in lower heat generation and therefore less electricity production. In short, solar panel is a process of converting light into electricity.
2. Traditional solar water heaters, on the other hand, convert light into heat.
******That's why we can store the electricity from solar panel in batteries, but we can't store the electricity generated by solar water heaters in batteries.******

How is the solar panel at work?
and their relationship with batteries!
***1.Does a higher total power of solar panels mean a faster way to fully charge a battery?***
……Answer: No!!!
1. Strong, direct sunlight is required, with surrounding obstructions, making desert solar power generation the preferred option.
2. The conversion of sunlight into electricity necessitates the use of an MPPT (Multi-Level Photovoltaic Tracking) controller, which automatically tracks sunlight to maximize conversion efficiency.
3. High-efficiency monocrystalline silicon solar panels are essential, boasting conversion rates exceeding 25%.
4. While the solar panels are charging the battery, is the load also working? The greater this load, the less charge the battery can store. (This is analogous to filling a water tank with water while others are using it; the more people using it, the longer it takes to fill the tank).

Spend a minute to understand the relationship and working principle of solar panels, batteries, inverters and electrical appliances.
1. The Solar panels are like a fixed water source, and the size of the water source is affected by the weather.
2.The battery is like a reservoir, but the amount of water flowing in determines how long it takes to fill the reservoir.
3. The inverter is like a faucet, and the power of the inverter is like adjusting the faucet.
4.The load is all the electrical appliances, which is like multiple people drinking water. The power of the appliances is different, just like the amount of water a child and an adult drink each day is different.
