Generally speaking, solar charge controllers are divided into MPPT solar charge controller and PWM solar charge controller. The size of solar charge controller mainly depends on two factors: the current flowing from the solar cell and the voltage connected to the system. Sizing a solar charge controller requires the following steps:

 

Step 1: Determine solar cell specifications First, you need to determine the wattage, voltage, and current of each solar panel.

 

Step 2: Match battery voltage Make sure the charge controller voltage matches the battery. If they do not match, it is easy to damage the battery and pose a safety hazard.

 

Step 3: Calculate maximum current output Calculate the maximum current output in parallel: With a parallel connection, the voltage remains constant as the current accumulates, adding current from each panel. When solar panels are connected in series, the current remains the same but the voltage increases. So if you have solar panels in series, you need to add voltage.

 

Step 4: Add security scope The safety margin is added to account for increased current due to strong sunlight conditions or other circumstances. A common practice is to add 25%.

 

Step 5: Consider future expansion We often choose a larger charger than the system we are currently using. This avoids the need to replace a larger charger when the system is expanded, adding a lot of convenience for future expansion.

Cost-Effective:

PWM (Pulse Width Modulation) solar charge controllers are generally less expensive compared to MPPT (Maximum Power Point Tracking) controllers. This makes them an attractive option for smaller or budget-conscious solar power systems .

 

Simplicity:

These controllers are straightforward in design and operation. Their simplicity makes them easier to install and use, requiring less technical expertise and fewer adjustments than MPPT controllers .

 

Reliability:

With fewer complex components, PWM controllers tend to have a longer lifespan and are less prone to failure. Their robust design ensures consistent performance over time with minimal maintenance .

 

Three-Stage Charging:

Many PWM controllers offer a three-stage charging process (bulk, absorption, and float), which optimizes the battery charging process and prolongs battery life by preventing overcharging .

 

Temperature Compensation:

PWM controllers often include temperature compensation, which adjusts the charging voltage based on battery temperature. This feature helps to optimize battery charging efficiency and extends battery life in various environmental conditions .

 

Cons

Lower Efficiency:

PWM controllers are less efficient than MPPT controllers, especially in systems where the solar panel voltage is significantly higher than the battery voltage. They do not convert excess voltage into additional current, which can lead to wasted energy ​.

 

Limited Application:

They are not ideal for larger solar systems or situations where the solar array voltage greatly exceeds the battery voltage. In such cases, MPPT controllers are more effective in harnessing the maximum power from the solar panels .

 

Performance in Cold Weather:

In cold weather conditions, solar panels typically produce higher voltages. PWM controllers cannot fully utilize these higher voltages, leading to lower overall system efficiency compared to MPPT controllers, which can adapt to these conditions more effectively .

 

Less Optimal for High Voltage Panels:

When using high voltage solar panels, PWM controllers are not as effective. They are better suited for low voltage solar panels and battery systems, which limits their flexibility in various solar power setups.

 

No Maximum Power Point Tracking:

Unlike MPPT controllers, PWM controllers do not track the maximum power point of the solar panels. This means they cannot always ensure the most efficient energy harvest, leading to potential energy losses, particularly in systems with varying sunlight conditions.

RFID (Radio Frequency Identification) electronic tag technology and NFCNear Field Communication) technologies are both wireless communication technologies, but they have some differences in working principles, communication ranges and application fields. Let’s find out next.

In terms of working principle, RFID technology uses radio frequencies to transmit data from electronic tags to RFID tag readers. The electronic tag contains a chip and an antenna, through which it receives and sends wireless signals and communicates with the reader. NFC technology is based on RFID technology, but has richer functions. It supports point-to-point communication and is compatible with existing RFID infrastructure. NFC devices can operate as RFID readers or tags, while also enabling direct communication between two NFC devices.

In terms of communication range, the communication range between RFID tags and readers is relatively large, usually up to several meters to tens of meters or even hundreds of meters, and can achieve long-distance identification and tracking. The communication range between NFC devices is usually short, generally within a few centimeters, and the devices need to be close to each other to communicate. This limitation of near-field communication makes NFC more advantageous in terms of security and is suitable for some payment and authentication scenarios.

In terms of application scope, RFID is widely used in supply chain management, inventory control, logistics tracking, asset management and other fields. It can identify and track a large number of items and improve logistics efficiency. NFC is mainly used in mobile payment, access control, smart tags, transportation cards on smartphones, ID cards and other fields. NFC technology allows smartphones to interact with NFC tags or readers, making it convenient for users to perform payment and authorization operations. It is worth mentioning that in many scenarios where NFC is used, RFID can also be used.
