12v 24v 48V Aluminum Alloy MPPT Solar Power Charging Photovoltaic Controller Regulator(MPPTAL50A )

Feature: 1. Adopting advanced polyphase synchronous rectification technology, has high conversion efficiency under low power charging environment. 2. The system adopts general negative circuit, which makes the system work more stable and reliable. 3. Advanced MPPT maximum power point tracking technology, tracking efficiency is not less than 99.5percent . 4. Support data storage function, storage time up to 10 years, long service life, can be used in a variety of harsh conditions. 5. With imported components and advanced power conversion circuit, maximum conversion efficiency can up to more than 98percent , full load efficiency can up to 97percent . 6. In 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 charging.
