6 FAQs about [PV inverter arrival acceptance process]
How to validate PV plant performance at provisional acceptance phase?
To validate the PV plant performance at Provisional Acceptance phase, the PR test is conducted over a limited period and compared to the guaranteed PR, set based on simulations. The usual duration of PR tests is 7 to 15 days, depending on the contract.
What happens if a PV inverter fails?
An insulation failure in a PV system circuit presents dual hazards of fire and lethal electric shock. Insulation failures can also impact the energy production of the system by tripping the GFDI (ground fault detection and interruption) device and taking the inverter offline.
What is penetration testing in PV inverter?
Penetration testing provides a detailed overview of PV inverter security issues. The analysis is conducted by simulating a real hacker attack during the prototype development phase.
What should be done before energising a photovoltaic system?
Before the plant is energised, a series of functional tests and measurements should be undertaken as per the reference norm IEC 62446: Grid connected photovoltaic systems. Minimum requirements for system documentation, commissioning tests and inspection for all electrical commissioning.
Why should you prevent quality issues in your inverters & power conversion systems?
Proactively catching and preventing quality issues in your inverters and power conversion systems optimizes the performance and extends the lifetime of your products. Preventing issues begins at the factory and production line.
What does efficiency mean in a PV inverter?
Efficiency is the core index of the performance of a PV inverter; it is closely related to the power generation capability of the overall PV system. We provide customers with the most comprehensive efficiency testing services according to standards such as CEC, IEC 61683, IEC 62891, EN 50530, CGC/GF 035, etc.
