Among the protection measures offered by this variable speed drive are protection against PV overvoltage, PV reverse polarity, and automatic power reduction in case of excess temperature. These features help ensure safe operation and extend the device's lifespan.
It uses an MPPT algorithm with 99% efficiency to reduce solar installation costs. Models with a capacity equal to or less than 2.2kW can be configured with a boost control to operate at a lower voltage in the solar field (fewer panels). It can also switch between power sources from solar panels, the electrical grid, or a generator as needed.
For models with a capacity equal to or less than 2.2kW, there is the option to configure a boost control. This allows the variable speed drive to operate at a lower voltage in the solar field, resulting in a reduction in the number of required panels.
The soft start function helps protect motors from overload damage during startup. Additionally, this controller features protection against lightning, overvoltage, overcurrent, overload, etc., enhancing its safety during use.
