HF2 series solar controller is more exquisite. The newly designed display interface can present comprehensive data to the user. It also provides user-friendly installation and operation prompts while meeting functional requirements. The series offers dual USB output with maximum 5V 1.2A, and people can charge mobile phones, DC fans and other DC electronic devices. Various load control modes make the controller widely applicable to solar home systems, signal lights, solar street lights, garden lights and so on.
