When installing a grid connect solar power system you must have the approval of your local lines company. On several occasions in New Zealand, people wanting to install a grid connect solar power system on their homes have been denied by their local lines company. This is mainly due to the lines companies being concerned about being unable to manage the additional load on their network.
A solution is to connect a Zero Export Device to your solar power system, which will either stop or limit solar power being exported out to the grid.
Some devices can communicate with the local grid to understand their load requirements and can adjust the exported solar power to suit.
Your solar installer company will have the best solution available in New Zealand if this issue happens to occur. Below is a short list of zero export devices available worldwide;
