    Flexible Parallel Expansion
    Up to 10 PowerHill units can be paralleled per site. The master unit is pre- configured at the factory. Side- by- side installation minimises footprint. Scale on demand – reduce upfront CAPEX and add capacity easily later.
    Seamless On/Off- Grid Switching
    With DuLink technology, seamless switchover in <20ms protects critical loads. An economical second- level switching option is also available for different project budgets.
    PV + ESS Coordination – Maximise Self Consumption
    Supports direct communication with major third- party inverters. Dual- meter configuration enables real- time monitoring of PV generation and load. Advanced functions like zero- export, demand control, and real- time data tracking boost self- consumption and project returns.
    Auto Coolant Replenishment – Simplified O&M
    Industry- first auto- replenishment cooling unit. It monitors return water pressure and automatically refills from the tank when needed – no manual topping up. Coolant lasts 10 years without replacement, enabling truly low- maintenance operation.
    Low- GWP Refrigerant – Future- Proof Compliance
    Uses R513A refrigerant with GWP of 631 – approximately 70% lower than traditional R134a. Fully compliant with EU F- gas Regulation 2024/573, ensuring risk- free market access in Europe.
    C5 Anti- Corrosion Cabinet – High Environmental Adaptability
    Rated IP67 and C5 corrosion protection, suitable for coastal, high- humidity, high- salt- spray, and chemical plant environments. The built- in intelligent dehumidifier automatically maintains a dry interior for stable electrical insulation.
    DuLink & Local EMS – Easy Monitoring & Maintenance
    Minute- level visual monitoring, cell- level realtime data and alerts. No licensing, subscription, or forced upgrade fees. Software- hardware co- design delivers dispatch within ≤100ms. Open APIs enable seamless integration with third- party systems.
