С растущим использованием систем солнечных батарей, 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 (мАч)?
The milliampere hour (мАч) 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. Конкретно, 1mAh means that the battery can last for 1 hour at a current of 1 milliampere (магистр).
Its definition formula is:
1 mAh=1 mA x 1 час
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 ампер-час (Ах)?
Ампер, 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
What is Watt (Вт)?
Ватт (Вт) is a unit of power, symbolized W. It is commonly used to measure the energy required by an appliance to complete a job. Например, 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, такой как “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 (Чт)?
A watt-hour (Чт) 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 час. Формула:
Э(Чт)=P(Вт)×Т(час)
Среди них: E said energy (tile), P said power (ватты), T time (час).
Watt-hours are a widely used unit in the power industry, often used to measure battery capacity or the power consumption of appliances. Например, 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 инвертор.
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% capacity.
Также, в зависимости от того, где вы живете, 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. To convert between the two, we need to introduce a new unit: the watt-hour (Чт).
Mah converted to watts
To convert milliampere-hours (мАч) to watt-hours (Чт), we need to know the voltage (В) батареи. Conversion formula is:
Э (Чт) = E (мАч) * В (В) / 1000
Среди них: E energy (Чт) said (tile), Э (мАч) said the battery capacity (мАч), В (В) said the battery voltage (В).
Например, а 5000 mah, 3.7 V battery, its energy is: Э (Чт) = 5000 Икс 3.7/1000 = 18.5 Чт
Convert convert wh to watts
To convert watt-hours (Чт) to watts (Вт) requires knowing the time (часы). Formula is:
п (Вт) = E (Чт)/Т (час)
Например, 18.5Wh of energy consumes 18.5W of power in 1 час.
Combining the above two steps, we can directly to the mAh (мАч) converted to watt (Вт) :
п (Вт) = E (мАч) * В (В) / 1000 * Т (час)
Practical application: Energy calculation in solar energy systems
In solar systems, understanding the conversion of milliampere-hours, ватты, and watt-hours is critical. Например, 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.
Прежде всего, converts from mah battery capacity watt hour:
Э (Чт) = 12/1000 = 10000 Икс 120 Чт
Затем, according to the equipment the power calculation of the power supply time:
Т (час) = E (Чт)/п (Вт) = 120/50 = 2.4 часы
This means that the battery can power a 50W device for about 2.4 часы.
Заключение
Milliampere-hours (мАч), ватты (Вт), and watt-hours (Чт) 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.
