3.2.4 Regular Operational Frequency Range
The inverter can operate within its frequency range for at least the specified observation
time. The setting of conditions depends on whether the connection is due to a normal
operational start-up or an automatic reconnection after tripping of the interface
protection.
When the frequency level is outside the operational levels, the inverter will disconnect
from the grid. If a disturbance lasts less than the required protection time, the inverter
can reconnect to the grid once the frequency level goes back to normal levels after the
disturbance.
3.2.5 Reactive Power Regulation
The inverter is capable of operating in reactive power regulation modes for the purpose
of providing support to the grid. The reactive power regulation mode can be set via the
iSolarCloud App.
3.2.6 Load Control
The inverter has an integrated multiple-function dry-contact (DO relay), which can be
used for load control via a contactor.
User may set the control mode according to individual demand.
