The Middle East and North Africa are entering a new stage of renewable energy development. For many years, the region’s power systems were mainly built around centralized gas-fired generation. Today, large-scale solar PV, battery energy storage systems, grid modernization and digital energy management are becoming more important across Saudi Arabia, the UAE, Egypt, Morocco, Oman and other MENA markets.

The pace of investment is accelerating. The MESIA Solar Outlook Report 2026 summary notes that more than USD 19 billion in solar contracts were awarded across the GCC in 2025, reshaping power flow patterns and increasing operational complexity. Dii Desert Energy’s MENA Energy Outlook 2026 also reports that the region added nearly 15 GW of renewable capacity in 2025, with the identified project pipeline reaching 202 GW. In Egypt, the government plans to add 3 GW of solar capacity in 2026 and 600 MW of battery energy storage before summer, amid expected grid demand growth.

These developments show that MENA solar projects are moving beyond pure capacity expansion. The next challenge is how to monitor, control and integrate solar PV and BESS assets reliably.

For EPC contractors, solar-storage system integrators, project developers and energy management companies, reliable power monitoring is becoming part of project design — not just a later-stage equipment decision.

Why MENA Solar Projects Are Moving Beyond Capacity Expansion

In the early stage of solar development, project success was often measured by installed capacity, energy generation and grid connection. In the new stage, the key question is more operational:

Can the project measure energy flow accurately enough to support EMS, SCADA, grid interaction and long-term operation?

This matters because solar PV + BESS projects do not only generate electricity. They also store, discharge, export, import and balance energy according to load demand, grid conditions and project control strategies.

A PV project without reliable metering may still produce electricity, but the project team may not clearly understand whether the energy is being used, stored, exported or curtailed in the most effective way.

For EPC contractors and system integrators, field-level metering data is no longer optional. It is part of the foundation for commissioning, monitoring, troubleshooting and long-term performance management.

Why Solar PV + BESS Projects Need Better Electrical Visibility

MENA projects often operate in demanding environments, including high solar irradiation, large project sites, long cable runs, outdoor electrical cabinets and utility-scale power infrastructure. These conditions increase the importance of stable metering, reliable communication and complete technical documentation.

Reliable power monitoring helps project teams understand:

• PV generation output
• Battery charge and discharge behavior
• Grid import/export direction
• Site load consumption
• Auxiliary power use
• Distribution cabinet status
• EMS or SCADA control data

For asset owners, this visibility supports performance reporting and operational decisions. For EPCs, it supports commissioning and troubleshooting. For system integrators, it supports data integration and platform reliability.

In solar PV + BESS projects, metering data should not be treated as isolated electrical readings. It should be viewed as the data layer that connects field equipment, control systems and long-term energy management.

Why Metering Decisions Affect EPC Project Delivery

Metering decisions can directly influence EPC project delivery.

If the metering point is designed incorrectly, the project may require rewiring, additional devices or cabinet redesign during commissioning. If the Modbus register map is unclear, EMS or SCADA integration may take longer than expected. If bidirectional energy values are not clearly defined, grid import/export data may be misunderstood. If voltage and current ranges are selected incorrectly, the meter may be unsuitable for the actual installation point.

For EPCs, these problems can create hidden costs:

• Longer commissioning time
• Repeated communication debugging
• Delayed EMS/SCADA integration
• Unclear grid import/export reporting
• Difficulty verifying battery charge/discharge behavior
• Future batch inconsistency during project expansion

This is why power meter selection should begin with the application scenario and metering architecture, not only with product model or unit price.

Key Metering Points in PV and BESS Systems

Solar PV and BESS projects should define metering points according to energy flow, not only according to meter model.

This structure helps EPCs design a metering system that supports operation, not just energy reading.

A well-planned metering architecture can help answer practical questions:

• How much solar power is generated?
• How much energy is stored in the battery?
• How much energy is imported from or exported to the grid?
• Which loads consume the most power?
• Is the battery charging and discharging as expected?
• Can the EMS or SCADA platform read the required data clearly?

These questions should be clarified before meter selection.

AC Metering vs DC Metering in Solar-Storage Projects

AC meters are commonly used at grid connection points, PV inverter outputs, load-side circuits and distribution cabinets. They help measure grid import/export, site consumption and AC-side power flow.

DC meters may be needed when a project requires visibility into battery-side energy flow or DC cabinet monitoring. For BESS applications, DC data can support charge/discharge analysis, system diagnostics and storage performance tracking.

In some high-current or space-constrained BESS cabinets, additional current sensing may be required as part of the metering architecture. For example, Rogowski coils can be considered in applications where flexible installation, wide current range and fast response to dynamic current changes are required. They are not a replacement for every meter, but they can support current measurement in scenarios where traditional CT installation is difficult or where battery charge/discharge behavior needs closer visibility.

However, the need for AC metering, DC metering or additional current sensing depends on system architecture, inverter design, voltage and current range, installation location and EMS requirements. EPCs and system integrators should confirm the metering point before selecting a meter.

Communication with EMS, SCADA and Energy Management Platforms

Power monitoring data becomes valuable when it can be read reliably by EMS, SCADA or energy management platforms.

In many solar and storage projects, RS485 and Modbus RTU/TCP are practical communication options because they are widely used by system integrators. However, simply saying “Modbus supported” is not enough.

EPCs should check:

• Is the register map clear?
• Can the EMS or SCADA system read the required values?
• Are voltage, current, power, power factor and energy values available?
• Is bidirectional energy clearly defined?
• Is the data refresh rate suitable for the project?
• Are wiring diagrams and communication documents available?
• Can future batches maintain the same communication behavior?

These details can directly affect commissioning time and long-term system stability.

For system integrators, unclear data mapping can create repeated debugging work. A meter may measure correctly, but if the EMS cannot interpret the values clearly, the project may still face delays.

Meter Selection Checklist for EPCs and System Integrators

Before selecting meters for solar PV and BESS projects, EPCs should ask:

1. Is the meter used for PV, BESS, grid, load or auxiliary power monitoring?
2. Does the project require AC measurement, DC measurement or both?
3. Is bidirectional grid import/export metering required?
4. Is additional current sensing needed for high-current or space-constrained cabinets?
5. What voltage and current range must the meter or sensor support?
6. Is DIN rail, panel or cabinet installation required?
7. Which communication protocol is needed: RS485, Modbus RTU/TCP or Ethernet?
8. Does the project require fast data refresh?
9. Are register maps and wiring documents available?
10. What temperature range and installation environment must be considered?
11. Are certification requirements defined for the selected model and target market?
12. Can the supplier support sample testing and project configuration?
13. Will future batches maintain consistent parameters and communication settings?

These questions help avoid a common problem: selecting a meter that works as a standalone product but creates integration issues during project deployment.

In MENA solar PV and BESS projects, selection should begin with the application scenario, not only the product category. The same project may need AC meters, DC meters, bidirectional metering, cabinet-level monitoring and communication-enabled devices depending on system design.

How YTL Supports Application-Based Power Monitoring

For EPCs and system integrators working on solar PV, BESS and C&I energy projects, Zhejiang Yongtailong Electronic Co., Ltd. can support application-based meter selection across AC metering, DC metering, bidirectional energy measurement, DIN rail installation, panel-mounted meters and selected models with communication interfaces.

Instead of starting from a product model, YTL recommends confirming the metering point, voltage/current range, installation environment, communication protocol and certification requirements first.

For projects involving high-current cabinets, dynamic load monitoring or space-constrained installation, current sensing requirements should also be discussed according to the specific system architecture. The suitable solution depends on project voltage, current range, communication method, installation location, accuracy needs and operating environment.

Model selection should always be confirmed according to project voltage, current, communication, installation environment and target market requirements.

Conclusion

MENA solar PV and BESS projects are entering a more complex phase. As solar capacity grows and battery storage becomes more important, project success increasingly depends on reliable power monitoring and clear energy data.

For EPC contractors, system integrators and project owners, meters and current sensing devices are not just hardware components. They are part of the data infrastructure that supports EMS integration, SCADA visibility, grid import/export monitoring, battery operation, load analysis and long-term performance management.

A well-designed metering architecture can help solar PV and BESS projects move from capacity expansion to smarter operation.

Reliable energy data does not replace EMS, SCADA or control systems. But without reliable field-level data, these systems cannot make accurate decisions.
