With the increasing use of solar panel systems, we are gradually increasing the attention to the physical quantity knowledge of solar systems. When working with solar systems, it is crucial to understand the conversion of mAh to Watts and the relationship between them.
This article will detail the concept of these electrical units, calculation methods, and their significance in practical applications to help you better choose, purchase, and optimize solar panel systems.

What is milliampere hour (毫安时)?
The milliampere hour (毫安时) is a measure of the capacity of a battery, and the symbol is mAh. It represents how long a battery can sustain power under a given current. 具体来说, 1mAh means that the battery can last for 1 hour at a current of 1 milliampere (毫安).
Its definition formula is:
1 mAh=1 mA x 1 小时
Mah is an important attribute of the battery, especially when choosing a large energy storage battery pack or a recycling battery pack, knowing the capacity of the battery can help us evaluate its endurance and application scenarios.
What is the 安培小时 (啊)?
安培, like the milliampere-hour, is also a unit of energy, with the symbol Ah. 1 amp hour is equal to 1000 mah hour, and its conversion relationship is:
1 Ah= 1000mah
The ampere-hour is often used to describe larger capacity batteries, such as batteries for electric vehicles or home energy storage systems.
The relation between milliampere and ampere-hour
Since milliampere-hours and ampere-hours belong to different units of the same physical quantity, the conversion between them is very simple. Just remember: 1 = 0.001 Ah mAh
什么是瓦特 (瓦)?
瓦 (瓦) is a unit of power, symbolized W. It is commonly used to measure the energy required by an appliance to complete a job. 例如, a 100-watt light bulb indicates that it consumes 100 joules of energy per second.
In solar energy systems, watt is a key parameter. The power of solar panels is usually labeled in watts, 例如 “300W solar panels.” This value determines the amount of electricity the solar panel can generate per unit time, and is an important reference indicator when choosing a solar system.
What is watt-hour (瓦时)?
A watt-hour (瓦时) is a unit of energy with the symbol Wh. It represents the total amount of energy consumed or produced by an appliance per unit of time. 1 watt-hour represents the energy consumed by 1 watt of power running continuously for 1 小时. 公式是:
乙(瓦时)=P(瓦)×T(小时)
他们之中: E said energy (tile), P said power (瓦特), T time (小时).
Watt-hours are a widely used unit in the power industry, often used to measure battery capacity or the power consumption of appliances. 例如, a 5000mAh mobile phone battery is usually labeled as 18.5Wh, indicating the total energy it stores.
Why is convert mah to watts useful?
Using the mAh to Watts calculator goes hand in hand with knowing how many watts your home uses, so you can invest in a solar system at the right scale.
The conversion can also be used to measure the power consumed by appliances, so by knowing how many watts you can use, you can know the number of appliances that can be connected to the 逆变器.
This knowledge also helps prevent the inverter from becoming overloaded due to long-term use and degrading the battery. You should not allow the inverter to operate at less than 50% 容量.
还, 取决于你住在哪里, the power output of the system will vary. You can use NREL’s PV Watt calculator to estimate exactly how much power you can expect to generate.
Convert mAh to watts
MAh and watts are different physical quantities, milliampere-hours are used to measure battery capacity, and watts are used to measure power. 在两个之间转换, we need to introduce a new unit: 瓦时 (瓦时).
Mah converted to watts
To convert milliampere-hours (毫安时) 至瓦时 (瓦时), we need to know the voltage (V) 电池的. Conversion formula is:
乙 (瓦时) =E (毫安时) * V (V) / 1000
他们之中: E energy (瓦时) said (tile), 乙 (毫安时) said the battery capacity (毫安时), V (V) said the battery voltage (V).
例如, 一个 5000 mah, 3.7 V battery, its energy is: 乙 (瓦时) = 5000 X 3.7/1000 = 18.5 瓦时
Convert convert wh to watts
To convert watt-hours (瓦时) 至瓦特 (瓦) requires knowing the time (小时). Formula is:
磷 (瓦) =E (瓦时)/时间 (小时)
例如, 18.5Wh of energy consumes 18.5W of power in 1 小时.
Combining the above two steps, we can directly to the mAh (毫安时) converted to watt (瓦) :
磷 (瓦) =E (毫安时) * V (V) / 1000 * 时间 (小时)
Practical application: Energy calculation in solar energy systems
In solar systems, understanding the conversion of milliampere-hours, 瓦特, and watt-hours is critical. 例如, let’s say you have a 10,000mah, 12V energy storage battery and you want to know how long it will be able to power a 50W device.
首先, converts from mah battery capacity watt hour:
乙 (瓦时) = 12/1000 = 10000 X 120 瓦时
然后, according to the equipment the power calculation of the power supply time:
时间 (小时) =E (瓦时)/磷 (瓦) = 120/50 = 2.4 小时
This means that the battery can power a 50W device for about 2.4 小时.
结论
Milliampere-hours (毫安时), 瓦特 (瓦), and watt-hours (瓦时) are integral electrical units in solar systems. By understanding the relationship between them and the conversion methods, we can better design, optimize and use solar panel systems.
