500 MWac PV Plant in Oman to get 1500V SG250HX inverter solutions by Sungrow


Sungrow, the global leading inverter solution supplier for renewables, announced it will supply 1500V SG250HX inverter solutions to the 500 MWac IBRI II project in Oman, which is the largest utility-scale PV plant in the Sultanate to date, demonstrating the Company’s robust efforts in supporting Oman’s ambition of lifting the renewable energy mix by 10%. The delivery of inverter solutions will commence in Q2 this year.


A Landmark Independent Power Plant


The IBRI II PV project is an Independent Power Project (IPP) to be developed on a BOO (build, own, operate) basis. The $400 million project was funded on a debt to equity ratio of 70:30 and a consortium consisting of ACWA Power, Gulf Investment Corporation (GIC) and the Alternative Energy Projects Company (AEPC) has achieved the financial closure of it recently.


The project is expected to come online in the summer of 2021, barring aside any potential COVID-19 related considerations. It will supply clean power to state-owned utility Oman Power and Water Procurement Company (OPWP) under a 15-year contract. The plant can generate roughly 1,300 GWh annually, which is enough to power an estimated 33,000 homes and offset 340,000 tonnes of carbon dioxide emissions per year.

The project is located in a desert around 300 km west of Muscat with ample sunshine and abundant flat land. The system poses strict requirements on a minimized LCOE with cutting-edge PV technologies and the resilience to harsh conditions like high temperature and sand corrosion.

Sungrow’s SG250HX, the world’s most powerful 1500V string inverter, to be installed onsite is an ideal match to the project. The solution features 12 MPPTs with maximum efficiency of 99% and enables flexible block design allowing for up to 6.75 MW blocks. Compatible with bi-facial modules and tracking systems, the solution can significantly maximize ROI for a PV project.

The improved Power Line Communication (PLC) will decrease installation cost without excessive communication wiring. Equipped with 24-hour Static Var Generator (SVG) function, the solution can provide an instantaneous and effective response to power quality problems, enabling improved power system stability, reduced energy losses and complying with most demanding local power quality standards and grid codes, saving approximately $1,143,000.

Particularly with IP66 and C5 protection together with the smart forced air-cooling technology, the 250 kW inverter can operate without derating even the ambient temperature is up to 50 degree Celsius, strongly resilient to scorching deserts of Oman.

Tap More Potential in MENA

Rajit Nanda, Chief Investment Officer from ACWA Power commented that, as a leading developer, owner, and operator of power generation and water desalination plants, they have considerable experience in deploying PV Independent Power Plants worldwide. The Oman IBRI II Solar PV is expected to play a strategic role in building Oman’s renewable production capacity and ACWA Power is delighted to partner with best-in-class entities such as Sungrow, that will support them in delivering long-term sustainable benefits for all the stakeholders through providing advanced, tailor-made solutions such as the SG250HX to our customers.

He also added that, Sungrow and the SG250HX compliment their ongoing mandate to provide low-cost power to communities through utilizing the latest, most cost-efficient technologies and they look forward to working on this venture with them.

The 1500V 250 kW string inverter has been attracting around 3 GW orders since it was first rolled out in Intersolar Europe 2019. Sungrow is glad to decarbonize the local economy by bringing in more flagship products, stated James Wu, Vice President of Sungrow. He added to his comments that, It was another fabulous milestone they did in Oman, even in Gulf Cooperation Council. It once again demonstrated that growing number of customers are impressed by Sungrow competitive products and services.

Wu also mentioned, Sungrow supplied a 105 MW project in Oman which will be put into commercial operation soon.

As one of the most energetic PV and BESS players in the Middle East and North Africa (MENA), Sungrow has the regional hub established in Dubai. In addition to remaining a remarkable market share in Omani PV market, Sungrow expands its footprints in other key markets in MENA as well. With the 500 MWac project added to its portfolio, the Company is expected to hit 1 GW in this region.
