Solar Limiting System

How does solar export limiting work?

Excess solar power is first directed to charge the battery rather than exported to the grid. Only after the battery reaches full capacity (100% State-of-Charge) does the export limiting kick in. Why Implement Solar Export Limiting? From Western Power perspective, the primary reason for imposing export limits is to maintain grid stability.

What is a solar export limit?

However, with an export limit set, your system’s output adjusts in real-time to prevent too much excess solar power fed to the grid. Normally, on a sunny day, a solar PV system will generate solar power in proportion to irradiance. The result; a nice smooth bell curve. For example

How do I know if my solar system is export limited?

For example However, if your system is Export Limited, you’ll notice that the solar PV graph fluctuates up & down in parallel with the home Load. For example, below is a system dynamically adjusting solar power production to achieve a 1.5kW Export Limit.

How does law 13-19 affect solar energy production?

Law 13-19 prohibits the self-producer from feeding back the energy produced to the grid, imposing conditions on PV systems, such as implementing a Zero Feed-in system when connected to the grid. In concrete terms, Zero export implies: No part of the solar energy produced by the system is allowed to enter the grid.
