What happens if a solar breaker exceeds a busbar's current limit?

When the load becomes greater than the current provided by solar, the grid must supplement to cover the load. If the current load exceeds the sum of the main break and the solar breaker, the busbar's published current limit could be exceeded.

What is the 120% rule on a solar panel?

If I The 120% rule is applied to the bus rating of the panel to find the maximum overcurrent protection that be added. IE it is 120% of the bus rating minus the main breaker rating to provide the amount of additional loading the solar can add.

How much breaker rating should a solar system have?

The rule specifies that the sum of the main breaker rating and the solar system's breaker rating must not exceed 120% of the busbar's rating. This ensures that even when the solar system is producing maximum power, there is a sufficient safety margin within the panel's capacity. For example:

What happens if a load is less than solar?

As long as the current consumed by the load is less than the current supplied by solar, the current feeds back to the grid. When the load becomes greater than the current provided by solar, the grid must supplement to cover the load.
