Power quality & injection testing

Winki: Your Partner for Safe and Compliant Commercial Solar Systems

Your commercial solar plays a critical role in your business's sustainability and financial goals. To ensure these systems operate optimally and meet safety regulations, injection testing is a vital step.

‍

Injection tresting is mandatory for systems larger than 30kVA

It is mandatory that all new solar installations above 30kVA have secondary protection devices installed. Popular devices are the Mainspro or Intelipro offerings. Electricity Distributors (DNSPs) require that these relays are tested for a range of electrical parameters to ensure the generation is compliant with their network.

‍

Winki's trained and qualified technicians can assist with not only injection testing, but the whole solar system commissioning process on site. We will liaise with the DNSP to ensure compliance and approval for the solar system to become live and connected to the grid.

What is injection testing for solar systems?

Think of it as a proactive safety check. During injection testing, we simulate potential grid anomalies, like voltage and frequency fluctuations, by injecting specific electrical signals. This evaluates the response of your system's protective relays, guaranteeing they effectively isolate your solar system from the grid in case of real-world faults.

‍

Why is injection testing crucial for your business?

Without proper injection testing, your solar system could face several risks:

‍

• Non-compliance: Failure to meet grid connection regulations could lead to system shutdown, impacting your investment.
• ‍
• Equipment damage: Malfunctioning protective relays during faults could damage your own equipment or even the broader grid infrastructure.
• ‍
• Disruptions: In the worst-case scenario, the grid operator might be forced to disconnect your system, causing operational and financial losses.
