LONGi’s storage platform Hi-MO One Pro arrives in Greece as businesses seek to maximize the value of solar generation

LONGi has introduced Hi-MO One Pro in Greece, a commercial and industrial energy storage solution designed to help businesses maximize the value of solar generation, increase self-consumption, and strengthen operational resilience. The modular system provides 261 kWh of storage capacity and integrates five core technologies developed in-house by LONGi, including energy management, battery management, power conversion, thermal management, and the company's patented, TÜV-certified iCCS predictive safety technology. This unified architecture reduces system complexity, enables close coordination between hardware, software, and safety functions, and simplifies installation, operation, and long-term maintenance. Hi-MO One Pro supports applications including self-consumption optimization, peak shaving, backup power, microgrids, and hybrid photovoltaic-storage systems.

The introduction of Hi-MO One Pro reflects LONGi's strategy to complement advanced back contact solar technology with intelligent energy storage solutions. Greece's high solar irradiation creates favorable conditions for self-consumption and on-site energy generation. Businesses are increasingly seeking solutions that enable them to store and manage locally generated electricity more effectively and reduce reliance on electricity purchased from the grid.

One coordinated platform for energy management, storage, and safety

The Hi-MO One Pro combines smart energy management (EMS), battery management (BMS), power conversion (PCS), thermal management, and LONGi's patented iCCS predictive safety technology within a single system architecture. More than 80 percent of core system components are developed and manufactured in-house, enabling close integration between hardware, software, and safety functions.

The coordinated design reduces system interfaces and streamlines installation, commissioning, service, and long-term operation. Hi-MO One Pro provides 261 kWh of storage capacity and is available with either 125 kW or 250 kW power conversion capacity. AC and DC cabinet configurations support a wide variety of commercial and industrial deployment scenarios.

Predictive safety technology provides earlier warning of battery abnormalities

A key feature of the Hi-MO One Pro is LONGi's patented iCCS predictive safety technology. The TÜV-certified early warning system continuously evaluates battery behavior at cell level using parameters including voltage, temperature, gas generation, valve activity, electrolyte leakage, and internal resistance.

The system can identify changes in internal resistance up to three to six months before potentially critical thermal developments occur. It can also detect abnormal gas generation more than 25 minutes before critical conditions develop and identify safety valve openings three to five minutes before a potential thermal runaway event. These capabilities provide operators with earlier visibility into battery health and additional response time.

The safety architecture combines predictive monitoring with combustible gas detection, exhaust systems, aerosol fire suppression, and smoke and thermal detection. The platform complies with NFPA 855 and relevant IEC and UL standards. This approach supports proactive maintenance planning, reduces downtime risk, and contributes to reliable operation throughout the lifetime of the system.

Pre-configured energy management reduces commissioning effort

Hi-MO One Pro includes an integrated Energy Management System that arrives pre-configured for European grid requirements and minimizes on-site commissioning effort. The system coordinates charging, discharging, and grid interaction in real time and supports functions including peak-valley optimization, demand response, anti-reverse power flow control, backup switching, and remote operation and maintenance.

Direct communication between the EMS and LONGi's iCCS predictive safety technology enables coordinated control across energy management and battery protection functions. This unified architecture provides greater visibility into energy performance and simplifies operation across commercial and industrial energy systems.

Flexible integration of solar generation and storage

Hi-MO One Pro integrates photovoltaic generation directly through a 63 kW MPPT input and supports coordinated operation with grid supply, diesel generators, battery storage, and electrical loads within a single cabinet architecture. The platform supports applications including self-consumption optimization, peak shaving, demand response participation, and hybrid photovoltaic-storage-diesel systems.

Businesses can use the platform to store excess solar generation, optimize electricity consumption patterns, and reduce dependence on externally purchased electricity. Intelligent energy management and storage capabilities improve utilization of renewable generation and help businesses make more effective use of available grid capacity.

Modular architecture supports future growth

Hi-MO One Pro uses a modular cabinet architecture that allows storage capacity to expand alongside operational requirements. In AC configuration, multiple units can be connected in parallel to increase both power and capacity. In DC configuration, additional cabinets can be added to extend storage capacity independently of power output.

Depending on system design and load profile, the platform can provide backup durations of up to 24 hours and support continuity of critical operations during grid interruptions. The modular architecture supports phased investment and maintains a consistent system design throughout the project lifecycle.

Solar growth increases the value of energy storage in Greece

Greece continues to strengthen its position as one of Europe's leading solar markets. Installed photovoltaic capacity reached approximately 11.5 GW by the end of 2025, supported by strong solar resources and continued investment in renewable energy projects. Commercial and industrial businesses are increasingly seeking ways to maximize the value of on-site solar generation, improve self-consumption, and reduce exposure to electricity price volatility.

The growing share of renewable electricity increases the importance of solutions that can store, manage, and optimize energy more effectively. Energy storage combined with intelligent energy management enables businesses to capture more value from solar generation, improve operational flexibility, and strengthen resilience during periods of grid disruption or peak demand.

Hi-MO One Pro was developed to address these evolving requirements. The platform combines energy management, storage, and predictive safety capabilities within a single coordinated architecture. As solar deployment continues to expand across Greece, energy storage is becoming an increasingly important component of long-term commercial and industrial energy strategies.
