Preface
Purpose
This document applies to the SmartLogger3000 data collector series (SmartLogger
for short). Read this document before you use the SmartLogger. As a dedicated
platform for photovoltaic (PV) power system monitoring and management, the
SmartLogger implements the interface convergence, protocol conversion, data
collection, data storage, centralized monitoring, intelligent maintenance, and
remote networking functions for devices in a PV power system.
This manual describes the operation and maintenance instructions of the export
limitation function.
Intended Audience
This document is intended for :
● Technical support engineers.
● Maintenance engineers.

1 System Network Diagrams
The Export Limitation feature is mainly used in the self-use scenario. The
SmartLogger detects the active power of the grid-tied point electric meter,
controls the active output of the inverter in a closed-loop manner, prevents the
inverter output power from being transmitted to the power grid, and maximizes
the inverter power generation for local load consumption.
Without the DO control circuit breaker

Pay attention to the power supply position of the SmartLogger. Avoid powering o
the SmartLogger after the DO control circuit breaker is switched o.

● If the connected power meter model is UMG604, PD510, PZ96L, UPM209, or COUNTIS
E43, select the corresponding model in the Intelligent Power Meter Type drop-down
list box.
● When the UPM209 or COUNTIS E43 power meter is connected to the SmartLogger, a
120-ohm resistor needs to be connected to the RS485 bus of the meter. For details, see
the user manual of the power meter.
● COUNTIS E43:Not applicable to Load Imbalance.
● The meter which used for Export Limitation, set the "Meter usage" to "Export +
import meter". Each array allows only one export+import meter to be connected.
