Solar System Export

What is solar export control?

In essence, solar export control refers to the amount of solar power you can send to the grid from a grid-connected solar installation. These limits can apply to any size of solar installation, from utility-scale projects to solar panels on private residences. Suppose a solar plant produces more electricity than can be supplied to the grid.

How do solar export limiters work?

Solar export limiters work through a smart meter installed into the system. This smart meter monitors the amount of electricity being produced as it passes through the system. Once the set threshold is reached, the smart meter sends signals to the inverter to switch off and stop any more power from being exported to the grid.

What is solar-log ® grid export control?

Solar-Log’s grid export control functionality means you can still collect RECs and at the same time adhere to the local utility’s required solar feed-in limitation. Solar-Log ® models are flexible to meet the different regulatory and operating requirements from individual countries and grid operators.

What if a PV system exports too much power?

This is the maximum amount of power the system is allowed to export onto the grid. If the balance between PV generation and self-consumption reaches a point where the system might export more than this value, then the Cluster Controller or Sunny Home Manager can tell the inverters to limit their production.
