The Hoymiles Smart Power Export Management can intelligently control the output power of the photovoltaic system, and maximize the user’s power generation profits 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 S-Miles Cloud.
In Hoymiles Export Management solution, Hoymiles gateway DTU-Pro (or DTU-Pro-S) 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.
