The Smart Energy Council has been working hard to find a resolution to the short circuit design calculation issue that may affect some inverter and panel combinations.
Inverter manufacturers will need to make a declaration to their customers around the safe short circuit current operating parameters of their product. The manufacturer should confirm that the equipment has been tested and shown capable of withstanding the maximum short circuit current. The manufacturer should then reflect that new tested rating in its data sheet. Manufacturers should note that designers/installers will rely on this statement to justify their design decisions.
Remain Engaged with the Issue
While there is no mechanism to allow an official ruling to be made on this issue, we have liaised with relevant stakeholders, who are supportive of the resolution outlined above. The Smart Energy Council will continue to monitor this issue and keep you updated if there are any changes in the future.
We Need to Fix This Hot Mess
The regulation of distributed energy resources, like solar panels and inverters, and the Standards process for them is broken. It must be fixed!
The Smart Energy Council is absolutely committed to reform in this area. We need your help to make this happen.
