Smart Power Export

Management System

The Solenso Smart Power Export Management can intelligently control the output power of the photovoltaic system, and maximize the user’s power generation pro its without violating grid export regulations. At the same time, this system can also accurately display the power and production of the photovoltaic system with the measuring meter, so that users can trade the PV production online according to data on Solenso Cloud.

In Solenso Export Management solution, Solenso gateway DTU-SLS and additional meter (CT optional) are necessary. In the case of export limitation, the meter can be installed at the load side or the grid side. As shown below, the gateway DTU will dynamically adjust the PV power production according to the export power or load consumption as measured by the meter, so that the export power does not exceed the preset limit. To display the PV production in an accurate way, the meter needs to be installed at the output of the PV system to enable the user to get the PV power production remotely

System Composition

—

DTU-SLS

As the control center of export management solution, DTU receives data from the meter and adjusts the output power of the microinverters.

Single-phase electric meter(Via Current Transformer)

Single- phase electric meter can be connected to the circuit and used to measure the PV power production, load consumption and export power. When the meter cannot be directly connected to the circuit or the system capacity is a little higher, a single-phase meter with the external current transformer is preferred.

Suitable for single-phase power grid

Three-phase electric meter (Via Current Transformer)
Three-phase electric meter can be connected to the circuit and used to measure the PV power production, load consumption and export power. When the meter cannot be directly connected to the circuit or the system capacity is a little higher, a three-phase meter with the external current transformer is preferred.

Suitable for three-phase and split-phase power grid
