How Recreen Energy designed a reliable commercial solar and battery storage solution with integrated hybrid inverters, fast STS switching, modular redundancy and future EV charging expansion.<\/strong><\/p>

Project Overview<\/h2>

What happens to a commercial business when the utility grid suddenly fails?<\/p>

For retail stores and other commercial facilities, an unexpected power outage can interrupt daily operations, affect essential equipment and create unnecessary business losses.<\/p>

That is why a successful commercial energy storage project should deliver more than battery capacity. It should also consider power supply reliability, grid-to-off-grid switching speed, system redundancy and long-term energy management<\/strong>.<\/p>

In Jordan, Recreen Energy supplied a 150kW\/651kWh commercial and industrial battery energy storage system (C&I BESS)<\/strong> for a retail store, integrated with a 250kWp solar PV installation.<\/p>

The system consists of three 50kW\/217kWh hybrid ESS units. Each cabinet integrates a 50kW hybrid inverter with built-in MPPT functionality and a Static Transfer Switch (STS) supporting 10ms on-grid\/off-grid switching<\/strong>.<\/p>

The customer’s existing electrical load is approximately 90kW. Instead of selecting a system based solely on this load, Recreen recommended a 150kW modular configuration to provide additional power capacity and improve system redundancy.<\/p>

The operating strategy is equally important: solar PV and battery discharge support the store’s daytime electricity demand, while the batteries recharge from the utility grid at night when consumption is lower.<\/p>

The customer also operates several EV charging stations near the store and plans to expand battery storage capacity to support future charging demand.<\/p>

This project demonstrates how integrated hybrid energy storage can combine solar generation, fast backup power switching, flexible energy management and future scalability<\/strong> in one commercial solution.<\/p>

1. The Challenge: Reliable Power for a Commercial Store<\/h2>

The retail store operates with an electrical load of approximately 90kW, with higher energy consumption during business hours and lower demand at night.<\/p>

The customer planned to combine a 250kWp solar PV installation with battery storage to better manage daily electricity consumption.<\/p>

However, energy management was only part of the requirement.<\/p>

The customer also needed a solution capable of responding quickly to grid interruptions, providing additional system redundancy and supporting future business expansion.<\/p>

Fast Switching During Grid Outages<\/h3>

When the utility grid becomes unavailable, commercial operations can be affected by a sudden loss of electricity.<\/p>

A conventional grid-connected solar inverter generally stops supplying power during a grid outage unless it is part of a properly designed island-capable system.<\/p>

For this project, the customer required a hybrid solution capable of transitioning between grid-connected and off-grid operation.<\/p>

Recreen’s integrated hybrid inverter includes an STS function with a specified switching time of 10ms, allowing the system to transfer to off-grid operation rapidly when the grid supply is interrupted.<\/p>

This helps minimize the duration of power interruptions for supported loads, provided the battery has sufficient available energy and the system is operating within its design limits.<\/p>

Redundancy for a 90kW Commercial Load<\/h3>

The customer also wanted to avoid depending entirely on one energy storage unit.<\/p>

Recreen therefore proposed three 50kW hybrid ESS units, providing 150kW of combined rated power.<\/p>

If one unit becomes unavailable, the remaining two units retain 100kW of combined rated power.<\/p>

This creates additional power capacity relative to the store’s approximately 90kW operating load.<\/p>

Future EV Charging Expansion<\/h3>

Several EV charging stations are located near the store.<\/p>

The customer plans to add more battery storage capacity as EV charging demand increases.<\/p>

The initial system therefore needed to support both the store’s immediate electricity requirements and future energy infrastructure development.<\/p>

2. Recreen’s Solution: Three Integrated 50kW\/217kWh Hybrid ESS Units<\/h2>

Recreen recommended a modular hybrid energy storage solution consisting of three 50kW\/217kWh integrated ESS cabinets.<\/p>

Each unit combines:<\/p>

  • 50kW hybrid solar inverter<\/li>\n\n
  • 217kWh lithium battery storage<\/li>\n\n
  • Built-in MPPT solar inputs<\/li>\n\n
  • Integrated STS with 10ms on\/off-grid switching<\/li>\n\n
  • Grid-connected and off-grid operating capabilities<\/li>\n\n
  • Coordinated solar, battery and utility grid energy management<\/li><\/ul>

    The complete installation provides 150kW of rated power and 651kWh of nominal battery storage capacity<\/strong>.<\/p>

    Unlike systems requiring separately installed hybrid inverters and battery cabinets, each Recreen unit incorporates the inverter directly into the energy storage cabinet.<\/p>

    This integrated design simplifies equipment arrangement and provides a compact architecture for commercial solar-plus-storage applications.<\/p>

    3. 10ms STS Switching: Rapid Transition from On-Grid to Off-Grid Operation<\/h2>

    One of the most important features of this project is the hybrid inverter’s integrated Static Transfer Switch (STS).<\/p>

    What Happens When the Utility Grid Fails?<\/h3>

    Under normal conditions, the hybrid ESS operates in grid-connected mode, coordinating solar generation, battery storage and the utility grid.<\/p>

    If the grid supply is interrupted, the system is designed to detect the abnormal grid condition and transfer supported loads to off-grid operation through the integrated STS.<\/p>

    The specified switching time is 10 milliseconds (10ms)<\/strong>.<\/p>

    This rapid transition helps reduce the duration of supply interruption and allows the battery system to continue supplying designated loads within the available inverter power and battery capacity.<\/p>

    When the utility grid returns, the hybrid system can transition back to grid-connected operation according to its control and synchronization requirements.<\/p>

    Why Does 10ms Switching Matter for Commercial Customers?<\/h3>

    For commercial facilities, switching speed can be an important consideration when selecting a hybrid energy storage system.<\/p>

    A fast transfer function can help:<\/p>

    • Reduce interruption time during utility grid failures<\/li>\n\n
    • Support the continuity of designated commercial loads<\/li>\n\n
    • Improve operational resilience<\/li>\n\n
    • Reduce dependence on manual backup power switching<\/li>\n\n
    • Combine daily energy management and backup power functions in one system<\/li><\/ul>

      The actual response of connected equipment depends on its tolerance to transfer interruptions, electrical configuration and operating conditions.<\/p>

      For highly sensitive equipment requiring strictly uninterrupted power, a dedicated UPS or additional power-conditioning solution may still be necessary.<\/p>

      By integrating STS functionality directly into the hybrid inverter, Recreen provides both energy management and rapid grid-to-off-grid switching within the same ESS architecture.<\/strong><\/p>

      4. Why Choose 150kW BESS for a 90kW Load?<\/h2>

      The customer has an existing electrical load of approximately 90kW.<\/p>

      From a simple power-sizing perspective, a smaller system might appear sufficient.<\/p>

      However, Recreen recommended three 50kW units to improve operational redundancy.<\/p>

      Normal Operation<\/h3>

      Three hybrid ESS units operate together, providing a combined rated power of 150kW.<\/p>

      One Unit Becomes Unavailable<\/h3>

      If one 50kW unit becomes unavailable, the two remaining units retain a combined rated power of 100kW.<\/p>

      This is above the store’s approximately 90kW operating load.<\/p>

      The design therefore provides a power-capacity margin intended to help maintain commercial operations if one unit is unavailable.<\/p>

      Actual continuity depends on the load at the time of the event, available battery energy, system control coordination, fault isolation and the electrical connection arrangement.<\/p>

      This project highlights an important principle:<\/p>

      Commercial energy storage should be sized not only for the current load, but also for reliability, redundancy and operational flexibility.<\/strong><\/p>

      5. 250kWp Solar PV Directly Connected Through Built-In MPPT<\/h2>

      The project integrates a 250kWp solar PV installation directly with the three hybrid energy storage systems.<\/p>

      Each 50kW hybrid inverter supports up to 100kW of PV input, providing a combined maximum rated PV input capacity of 300kW across the three units.<\/p>

      The installed 250kWp solar array connects directly to the hybrid inverters’ built-in MPPT inputs.<\/p>

      This creates a DC-coupled solar and battery storage architecture<\/strong>, without requiring separate PV inverters for the connected solar arrays.<\/p>

      Advantages of the Integrated MPPT Design<\/h3>
      • Direct solar PV connection<\/li>\n\n
      • Integrated solar and battery energy management<\/li>\n\n
      • Reduced external power conversion equipment<\/li>\n\n
      • Simplified equipment configuration<\/li>\n\n
      • Flexible operation between solar, battery and grid power<\/li><\/ul>

        The actual PV array distribution and string configuration are determined by the MPPT input voltage, current and power limits of each hybrid inverter.<\/p>

        For EPC contractors and commercial customers, this integrated approach provides a practical way to combine solar generation and battery storage within a modular system.<\/p>

        6. Customized Energy Management: Daytime Discharge and Nighttime Grid Charging<\/h2>

        The customer’s electricity consumption is higher during daytime business hours and lower at night.<\/p>

        Recreen designed the operating strategy around this daily load profile.<\/p>

        Daytime: Solar PV + Battery Discharge<\/h3>

        During the day, solar PV generation supplies electricity to the store.<\/p>

        The battery energy storage system also discharges according to the programmed operating schedule, helping support commercial loads and manage electricity consumption from the grid.<\/p>

        The hybrid inverter coordinates solar generation, battery discharge and utility grid power according to the system’s operating conditions.<\/p>

        Nighttime: Utility Grid Charging<\/h3>

        At night, when the store’s electricity demand decreases, the battery storage system recharges from the utility grid.<\/p>

        The stored energy is then available for the following day’s operations.<\/p>

        The operating cycle can be summarized as:<\/p>

        Daytime: Solar PV + Battery Storage \u2192 Retail Store Loads<\/strong><\/p>

        Nighttime: Utility Grid \u2192 Battery Storage<\/strong><\/p>

        This approach allows the customer to manage stored energy according to business operating hours.<\/p>

        Where suitable electricity tariffs apply, nighttime grid charging may also create opportunities for energy cost optimization.<\/p>

        Actual savings depend on local electricity rates, charging and discharging efficiency and the customer’s load profile.<\/p>

        7. Future Expansion: Solar + Storage + EV Charging<\/h2>

        The customer’s long-term energy plan also includes EV charging infrastructure.<\/p>

        Several EV charging stations are already located near the retail store, and the customer plans to purchase additional battery storage equipment to support future charging expansion.<\/p>

        As charging demand increases, energy storage can help manage peak power requirements, coordinate solar generation and support charging operations within the available electrical infrastructure.<\/p>

        A future integrated configuration could include:<\/p>

        Solar PV + Hybrid BESS + Retail Store Loads + EV Charging Stations<\/strong><\/p>

        Additional battery capacity and power conversion equipment would be selected based on charger ratings, simultaneous charging demand, grid connection limits and site operating requirements.<\/p>

        The current installation therefore provides a starting point for future energy infrastructure development.<\/p>

        Conclusion: A Commercial BESS Designed for More Than Energy Storage<\/h2>

        This Jordan project demonstrates how a commercial battery energy storage system can address multiple business requirements through one integrated solution.<\/p>

        For a retail store with an approximately 90kW electrical load, Recreen supplied a 150kW\/651kWh modular hybrid BESS integrated with 250kWp of solar PV.<\/p>

        The system combines direct solar integration, scheduled battery operation, integrated STS functionality and a redundancy-focused design.<\/p>

        With a specified 10ms on\/off-grid switching time, the hybrid inverter also provides a fast transfer capability that is important for commercial backup power applications.<\/p>
