Net Metering Approved Models (Educational)

Approval can vary by DISCO and time; always check current lists. Each Distribution Company (DISCO) in Pakistan maintains its own list of approved inverters for net metering. An inverter approved by one DISCO may not necessarily be approved by another. Additionally, these lists can change periodically as new models are tested and approved or as standards are updated.

Before purchasing an inverter, always verify its approval status with your specific DISCO's current approved list.

For net metering approval in Pakistan, you typically need the following documents:

• Inverter Datasheet: Technical specifications of the inverter model
• Compliance Certificates: Including but not limited to:
  • IEC 62109 certification (safety standard for power converters)
  • IEC 61727 certification (utility interface requirements)
  • ISO certification of the manufacturer
• Installer Accreditation: Proof that your installer is certified by the relevant authorities
• Application Form: Completed net metering application form from your DISCO
• Ownership Proof: Documentation proving ownership of the property
• Electricity Bill: Recent electricity bill for the connection where the system will be installed

Requirements may vary slightly between different DISCOs, so it's advisable to check with your specific electricity provider for their exact documentation requirements.

DISCOs in Pakistan typically update their approved inverter lists periodically, though the exact frequency can vary. Updates may occur:

• Quarterly or bi-annually as part of regular review processes
• When new inverter models are submitted for approval
• When standards or regulations change
• When performance issues are identified with previously approved models

It's recommended to check the official website of your DISCO or contact their customer service directly for the most current approved list before making any purchase decisions.

Installing an inverter that is not on your DISCO's approved list can have several consequences:

• Your net metering application may be rejected
• You may not be able to connect your system to the grid legally
• You could face penalties or fines for non-compliance
• You may need to replace the inverter with an approved model at additional cost

To avoid these issues, always verify that your chosen inverter model is on the current approved list for your specific DISCO before installation.

In some cases, it may be possible to get a new inverter model approved by your DISCO, but the process can be complex and time-consuming. The general steps include:

• Submit a formal request to the DISCO with complete technical documentation
• Provide all necessary compliance certificates and test reports
• Potentially pay a fee for the evaluation process
• Wait for the technical evaluation, which can take several months

For most residential and small commercial installations, it's generally more practical to choose from the existing list of approved inverters rather than attempting to get a new model approved.

No, imported inverters are not automatically approved for net metering in Pakistan. All inverters, regardless of their country of origin, must undergo the same approval process and appear on the DISCO's official approved list. Factors considered during approval include:

• Compliance with international standards (IEC, etc.)
• Safety certifications
• Performance and reliability in local conditions
• Compatibility with Pakistan's grid infrastructure

Always verify the approval status of any inverter, whether imported or locally available, with your DISCO before purchase.
