Ramp Rate Settings

The feature allows the inverter to establish ramp-up rates for solar systems. It helps smooth transitions from
one output level to another output level.
Although a single system might not impact the electric grid through a single sharp transition, aggregated
systems responding to a specific event could cause significant rapid jumps in overall output if they do not
ramp to the new power level.
The image below shows the default setting of Ramp Rate functions. The default setting for normal ramp rate is
100% of rated current per second and 2% of rated current per second for inverter soft-start ramp rate.
Example:
If the cutomer wants to implement a much slower ramp rate (1% of rated current per second) during normal
operation, and the customer also wants to have a really fast recover during soft-start (100% of rated current
per second). The procedure via web-based GUI is shown below.
Write “ 1.0 ” to ramp rate
Write “ 100.0 ” to soft start rate
Click Save button to apply the settings to local inverter
The alternative method is to use software which supports Modbus TCP/IP. The register address is shown
below.
