The Busbyr photovoltaic water pump inverter series products adopt a combination of dynamic VI maximum power point tracking (MPPT) and motor control
Key Features
● Supports single-phase motor direct drive (without removing the starting capacitor), as well as three-phase 220V motor.
● Equipped with one drag and multiple functions, supporting vector control IP65 protection level, fanless design, all use quick connect terminals, easy and fast installation and use; Adapt to various harsh outdoor application environments.
● Equipped with bypass function, it can support AC 220V input for mains power and diesel engine input; Optional water level detection module and diesel engine start stop module.
● Low voltage startup and wide input voltage range, suitable for a wider range of solar panel types and string configuration schemes.
● Digital intelligent control, with the ability to freely set the speed range of the water pump
● ACS indicates that AC input is provided and a DC switch is configured.
