Generally includes demand communication, solution design, production and manufacturing, testing and inspection, delivery and other links. The specific process may vary from manufacturer to manufacturer.

The operating voltage range of different models and customized controllers may be different. The common ones are 12V, 24V, 48V, etc., which can be determined according to the customized requirements.

When installing, pay attention to choosing a suitable installation location to avoid direct sunlight, rain and high temperature environment; ensure that the connection line is correct and firm to avoid short circuit and poor contact; strictly follow the product manual for installation operations.
