Solar Controller
There are two types of solar charge controllers(Also known as solar regulator): MPPT automatic maximum power point tracking and PWM pulse width control.

There are two main types of solar charge controllers: PWM (Pulse Width Modulation) and MPPT (Maximum Power Point Tracking). Understanding the characteristics of these two solar controller types can better meet the needs of different solar systems and ensure that the system can operate effectively under various conditions.

 

MPPT Charge Controller
1. Working principle: The MPPT charge controller continuously adjusts the voltage and current between the battery and the solar panel to achieve maximum power point tracking. This means it optimizes energy conversion, ensuring maximum power point electrical energy output under different cue conditions.
2. Advantages: High efficiency, especially when conditions change greatly. Maximum power point tracking improves overall system performance. Ideal for large solar systems and applications requiring harvested energy harvesting.
3. Disadvantages: relatively complex and higher cost. In some small solar systems, this may exceed actual requirements.

 

PWM Charge Controller
1. Working principle: PWM charge controller controls the charging process by switching current between the solar panel and the battery. It delivers electrical energy to the battery in pulses to maintain the proper voltage of the battery.
2. Advantages: relatively simple and low cost. Suitable for small-scale solar systems. Can prevent overcharge and over-discharge.
3. Disadvantages: The efficiency is relatively low, especially when the lighting conditions change greatly. It does not have the maximum power point tracking function, which may lead to a decrease in system efficiency.

 

MPPT Solar Controller or PWM Solar Controller?
1. System size: For small solar systems, PWM solar controllers may be more cost-effective. For large solar systems, the performance of MPPT solar controllers is more advantageous.
2. Cost budget: PWM solar controllers are usually cheaper and suitable for projects with limited budgets. MPPT solar controller provides more efficient energy conversion, but the price is relatively high.
3. Environmental conditions: In areas where sunshine conditions are unstable or change greatly, the advantages of MPPT solar controllers are more obvious.
