Energy Live PV genset controller can be configured as a zero export device to prevent excess power generated by the solar panels from being exported back to the grid. This is typically done to comply with regulations or to avoid penalties for exporting power to the grid without permission. To work as a zero export device, the PV genset controller monitors the power output from the solar panels and the power consumption by the load. If the solar power generation exceeds the load demand, the controller limits the power output to prevent any excess power from being exported to the grid. The controller accomplishes this by dynamically adjusting the generator set's power output to match the load demand. When solar power production is high, the controller reduces the generator set's power output to avoid exporting power. Conversely, when solar power production is low, the controller increases the generator set's power output to meet the load demand. Overall, a PV genset controller can work as a zero export device by closely monitoring the power output and load demand, and dynamically adjusting the generator set's power output to prevent excess power from being exported to the grid. This helps to ensure compliance with regulations and avoid penalties while still allowing for efficient and reliable use of solar and generator power.
