User Manual
DRM (“AU”/”NZ”) The DRM function is only applicable to a single inverter. The
inverter provides terminals for connecting to a Demand Response Enabling
Device (DRED). After the connection, the DRED asserts demand response modes
(DRMs). The inverter detects and initiates a response to all supported demand
response modes listed in the following table.
table 2-2 Demand Response Mode Explanation
Mode Explanation
DRM0 The inverter is in the state of shutdown.
Feed-in Limitation Set the feed-in limitation value via iSolarCloud App. When
the smart energy meter detects that the export power is greater than the limit
value, the inverter will reduce the output power within the specified range.
PID Recovery The inverter is equipped with PID phenomenon recovery function to
improve the PV power generation. During the power generation process, the
inverter could carry out a main AntiPID function without any influence to the
grid side thanks to a particular technology. The PID recovery function is
disabled by default. Enable the function via iSolarCloud App when there is PV
power in the daytime. During the inverter standby process with no irradiance,
an additional PID recovery function could apply inverse voltage to PV modules,
to restore the degraded modules.
figure 2-6 PID Recovery Scheme
Keep the DC switch “ON” in the PID recovery process. During the process, there
is voltage hazard between inverter / PV module live conductors and ground. Do
not touch any of them.
When the PID recovery function is enabled, there will be a power consumption
of less than 30 W in the PID recovery process.
