Maximum Power Point Tracking (MPPT) is a key technology in photovoltaic systems that is used to regulate the working state of the electrical module to ensure that the solar panels can output the most energy and efficiently store it in the battery.
How it works:
MPPT optimizes charging efficiency and overall system performance by monitoring the generation voltage of the solar panel in real time and tracking its maximum power output point, allowing the system to operate at that point. The application of this technology in photovoltaic power generation system is to solve the problem of fluctuations in the output power of solar panels caused by changes in the external environment such as light intensity and temperature, MPPT can ensure that solar panels always work at the best working point, there by improving the entire power generation efficiency of the system.
The difference between MPPT and PWM:
Maximum power point tracking (MPPT) and pulse width modulation (PWM) are two controller technologies used in solar systems that differ in terms of technical maturity, system efficiency, and cost.
- Mature technology: MPPT technology is more advanced, can ensure that the solar panels always work at the maximum power point, improve the efficiency of the system. Suitable for high-power application scenarios, such as solar power stations and motorhomes; PWM technology is more mature, the circuit is simple and reliable, easy to implement. Suitable for small off-grid systems, such as home and small business use.
2. System efficiency :MPPT can track the maximum power output of solar cells, so the module utilization rate is high, the whole machine efficiency is high, can make full use of the energy of solar modules; PWM is less efficient than MPPT because it does not guarantee that the solar module is always output at maximum power.
3. Input voltage range :MPPT allows a wide input voltage range, and the component voltage can be 1.2 to 3.5 times that of the battery voltage, providing greater flexibility; The PWM input voltage range is narrow, the component voltage is usually 1.2 to 2.0 times of the battery voltage, and each string can only be equipped with one or two components, which is subject to greater restrictions.
The MPPT has a wide input voltage range and can achieve the highest output power without significantly affecting battery life. In addition, MPPT also has an intelligent management system, which can be detected and adjusted through the intelligent management system.
To bring us the next is the Eternal Energy Tech products E – HYBRID Solar Charge Controller (30A/ 40A/ 60A/80A / 100A / 120 A), can satisfy the demand of power shortage areas. MPPT has a wide range of input voltages to achieve maximum output power without compromising battery life. In addition, MPPT also has an intelligent management system, which can be detected and adjusted through the intelligent management system.
