eMPPT-30 30A MPPT solar controller adopts DC/DC converting technology and MCU technology. It can adjust the working point of the 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.
