Description
【Overview】
MPPT, which stands for Maximum Power Point Tracking, continuously monitors the power generation voltage of photovoltaic (PV) modules and tracks the maximum voltage and current values (VI) to ensure that the PV modules always operate at their maximum power output. Under varying light intensities and temperature conditions, MPPT efficiently converts the direct current (DC) generated by solar panels into adjustable DC voltage. Compared to traditional controllers, the system tracking efficiency is improved by 50%, significantly enhancing energy utilization.
This MPPT module utilizes SiC devices, achieving a conversion efficiency of up to 99%. It supports RS485/CAN/Ethernet/dry contact communication, facilitating communication and control with third-party devices.
This module is widely applied in DC-coupled scenarios, such as DC microgrids, PV-storage direct, PV-storage-diesel, and many other fields, making it the preferred product for industrial and commercial energy storage.
【Product Advantages】
Adaptable to Diverse Scenarios
- Supports three MPPT channels, resulting in higher power generation. It perfectly matches mainstream 500~720Wp PV modules on the market. Each MPPT channel can operate independently for MPPT tracking, leading to higher power generation and efficiency.
- PV modules can be directly connected to the MPPT module, eliminating the need for a PV combiner box.
- Employs interleaved parallel technology to reduce DC ripple current and enhance battery lifespan.
Higher Efficiency
- Utilizes third-generation power semiconductor SiC devices, achieving a maximum efficiency of 99.2%. Compared to traditional IGBT devices, it offers higher efficiency, resulting in shorter payback periods and higher returns for industrial and commercial energy storage projects.
Smarter and User-Friendly
- The module has a height of only 2U, facilitating a more compact overall size for integrators.
- High power density and small product size make it easy for customers to install within cabinets.
- Supports multiple interfaces including CAN, RS485, Ethernet, and dry contacts.
