The factory makes platinum catalytic converters, and its heavy machinery draws large, sudden loads. A standard installation risked tripping and voltage instability on the production line.
The client set two conditions. The solar plant had to synchronise with the grid and the diesel back-up, and the installation could not stop production for a single minute.

Eight inverters share the array, so if one goes down, there are seven backups.
