Technical FAQs 4

What happens if a solar system is approved by a utility?

The utility will evaluate the system design, its impact on grid reliability, and the safety of its operation. Approval typically results in an Interconnection Agreement, a formal document granting permission to operate (PTO). Without this agreement, a solar system cannot legally go live. Utility interconnection isn’t just paperwork. It affects:

How many inverters can be connected to a MV station?

The Inverter Manager and the I/O Box can be installed in the MV Station as an option and can control the output of the inverters. Up to 42 inverters can be connected to one Inverter Manager. This means that PV systems can be designed with several MV stations, whereby not every MV station has to be fitted with an Inverter Manager.

What happens if a solar system is not approved?

Approval typically results in an Interconnection Agreement, a formal document granting permission to operate (PTO). Without this agreement, a solar system cannot legally go live. Utility interconnection isn’t just paperwork. It affects: Project Timelines: Delays in approval can push back commissioning dates by weeks or months.

Are PV systems interconnected to the grid?

While the number of PV systems interconnected to the grid has increased significantly over the last decade, only recently have PV systems been installed in major metropolitan areas and tied to electric distribution secondary network systems (networks).
