1、Advanced MPPT maximum power point tracking technology, tracking efficiency is not less than 99.5%, compared with ordinary PWM algorithm, the efficiency is increased by 15% to 20%. 2、Using high‑quality components and advanced power conversion circuits, the maximum conversion efficiency reaches over 98%, and the full load efficiency reaches 97%. 3、The structure is made of aluminum and can be used under various harsh conditions. Support data storage, the storage time can be up to 10 years. 4、Advanced multi‑phase synchronous rectification technology also has higher conversion efficiency in low power charging environment. The system adopts universal negative circuit, which makes the system work more stable and reliable. 5、In the current limiting charging mode, when the input power of the photovoltaic panel is too large and the charging current exceeds the rated current of the controller, the controller will limit the charging current to the rated current for charging.
