Product Overview:
HES7120-PV Hybrid Energy Controller can be used for solar energy control system with inverter. It can control the closing and opening of circuit breaker and the starting and stopping of the inverter, as well as the output power. According to the system application, it can be set to a variety of modes, including fixed power, busbar control power and inverter control power, etc., which can display all data and status of solar PV power generation. The controller integrates digitization, intelligentialize and networked technology, and adopts LCD, which can display Chinese, English and other languages, with simple and reliable operation.

HES7120-PV Hybrid Energy Controller adopts 32-bit microprocessor technology, realizing the functions of precise measurement, fixed value adjustment, timing and threshold setting of various parameters. Most parameters can be adjusted from the front panel of the controller, and all parameters can be adjusted by PC via USB or network interface. Its compact structure, simple connection and high reliability can be widely used in hybrid energy control system.
