DEWA DRRG Inverter and Equipment Eligibility Standards Guide

Key Takeaways

• DEWA requires inverters to be certified to IEC 62109-1 and IEC 62109-2 (or UL 1741) for safety (August 2026).
• Inverters must demonstrate an electrical conversion efficiency greater than 95% (August 2026).
• A minimum 10-year manufacturer warranty is mandatory for all eligible inverters (August 2026).
• Only equipment registered and listed on the DEWA DRRG Equipment Portal is permitted for installation (August 2026).

What are the DEWA DRRG inverter and equipment eligibility standards?

The Dubai Electricity and Water Authority (DEWA) Distributed Renewable Resources Generation (DRRG) scheme sets technical and safety standards for solar PV inverters and balance-of-system equipment. These standards ensure the safe and reliable integration of solar energy systems into Dubai's grid. All inverters must be fully certified to IEC 62109-1 and IEC 62109-2 or an equivalent UL 1741 safety standard (August 2026).

The table below details the primary eligibility provisions for equipment under the DEWA DRRG scheme.

How do we verify DEWA's equipment standards?

We verified these requirements by directly consulting the official DEWA Shams Dubai equipment standards documentation available on the DEWA website. Our review was conducted on 23 August 2026. The information presented reflects the "Technical guidelines governing equipment certification, inverters, and PV modules under the Shams Dubai initiative" and the section titled "Inverter Safety, Efficiency, and EMC Standards."

Why is equipment registration on the DRRG Portal critical?

DEWA mandates that "Only hardware approved and listed on DEWA's active online DRRG List of Eligible Equipment is permitted for installation" (August 2026). This means that even if an inverter meets all technical specifications, it cannot be used in a DEWA DRRG project unless it is registered. Manufacturers or their authorized local agents must register equipment through the online DRRG Equipment Portal. If equipment is not listed on the active DEWA DRRG Equipment Portal, it cannot be selected in Getting Solar Permits applications. Inverters that fail to provide certified test reports for IEC 62109 and IEC 61000 EMC are rejected during technical review. You must ensure any equipment you consider for your solar installation is on this official list.

What are the key technical requirements for DEWA-approved inverters?

DEWA specifies several technical requirements for inverters to ensure grid stability and safety. Inverters must achieve an electrical conversion efficiency greater than 95% across their normal operating range (August 2026). They must also comply with Electromagnetic Compatibility (EMC) standards, specifically IEC 61000-3-2 or IEC 61000-3-12, and IEC 61000-6-1 / IEC 61000-6-3 (August 2026). Crucially, inverters must incorporate certified anti-islanding protection, automatic disconnect upon grid failure, and power quality control to protect both the solar system and the wider grid (August 2026).

What warranty and certification documents are required?

A minimum manufacturer warranty guarantee of 10 years is mandatory for all inverters (August 2026). Beyond the warranty, proof of certification to IEC 62109-1 and IEC 62109-2 (or equivalent UL 1741) for safety, and IEC 61000 series for EMC, is essential. Without these certified test reports, inverters will be rejected during the technical review process.

How do these standards impact your solar project planning?

Understanding DEWA's equipment eligibility standards is fundamental for any solar PV project in Dubai. Selecting non-compliant or unregistered equipment will lead to project delays or outright rejection. Before purchasing any components, verify their compliance with the stated safety (IEC 62109-1 and IEC 62109-2 or UL 1741), efficiency (greater than 95%), EMC (IEC 61000 series), and warranty (10 years) requirements (August 2026). Always confirm that the equipment is listed on the official DEWA DRRG Equipment Portal.
