Communication abnormality
output (%)
Communication is abnormal, and specified dispatch
output value is delivered.
Control method
Open loop control：At the start time, the locally
configured active instruction is sent to the power
output port of the inverter, thereby implementing
active power control.
Closed-loop control:
•
In case no Smart Energy Meter is selected, at the
beginning time, the active instruction configured
locally is used as target value, and active power
compensation ratio is calculated and sent to the
power output port of the inverter. Generally, this
strategy is used for fast and accurate active
power regulation.
•
In case a Smart Energy Meter is selected, at the
beginning time, active instruction configured
locally is used as target value, active power of the
meter needs to be collected and used as input
parameter, and active power compensation ratio
is calculated and sent to the power output port of
the inverter. Generally, this strategy is used for
anti-backflow or avoiding zero power feed-in.

regulation
Wiring mode*
Direct connection: One Logger1000 is connected to
all inverters, where all the inverters must be string
inverters or central inverters.
Cascade connection: Multiple Logger1000 are
cascaded, and this Logger1000 is used as the host.
Start after communication
recovery *
Enable: After the Smart Energy Meter recovers
normal communication, the Logger1000 will deliver
start instruction to the inverter.
Disable: After the Smart Energy Meter recovers
normal communication, the Logger1000 will not
deliver start instruction to the inverter.
