Mô tả hoặc các tên gọi khác:eMPPT30 adopts DC/DC converting technology and MCU technology.
It can adjust the working point ofthe solar panels array intelligently to
make the solar panels array realize the maximum power output. When
the external condition changes, eMPPT controller bases on the MCU
theory to track the maximum working point of the solar panels, this
can improve the using efficiency of the solar panels and decrease the
solar generating cost. Compared with average solar charge controllers,
eMPPT can improve the output efficiency of the solar panels by 5% to
30%(the output increasing proportion affected by the factors such as
the attribute of the solar panels, environmental temperature and lighting
conditions). The product adopts in big screen lattice LCD, and uses the
vivid icons to indicate the parameters. It has concise and vivid interface.
The product is wall mounting installation. Please refer to chapter 2.1 for
the installing dimensions.
