Description

The FoxESS 27.84kWh CQ7 Energy Storage System combined with the H3 Series 10kW Three Phase Hybrid Inverter is a complete high-voltage three-phase residential and light commercial energy solution. The system consists of the modular CQ7 series high-voltage battery pack (expandable to 27.84kWh or higher) paired with a powerful 10kW three-phase hybrid inverter, supporting intelligent management of PV generation, battery storage, and grid on-grid/off-grid switching.

The CQ7 battery system features a modular stackable design, consisting of a Master control unit (CQM) and Slave expansion units (CQS), allowing for flexible capacity expansion up to 49.14kWh . Paired with the H3-10.0-E three-phase hybrid inverter, the system enables PV energy storage, peak/off-peak tariff arbitrage, and emergency backup power during outages.

Key Features

Energy Storage System (CQ7 Battery)

  • Modular & Expandable: The CQ7 system consists of 1 Master unit (CQM) and up to 6 Slave units (CQS). Minimum configuration requires 2 units (1 CQM + 1 CQS), maximum supports 7 units, with capacity ranging from 14.04kWh to 49.14kWh 
  • Safe LiFePO₄ Technology: Uses high-safety Lithium Iron Phosphate (LiFePO₄) cells, offering excellent thermal stability and cycle life
  • High-Voltage Architecture: Compatible with modern high-voltage three-phase hybrid inverters
  • Deep Discharge Capability: Supports high Depth of Discharge (DoD), maximizing usable capacity
  • High Protection Rating: IP65 rating, suitable for both indoor and outdoor installation 
  • Remote Monitoring: Monitor system performance via smartphone App or web portal (FoxCloud V2.0) 

Inverter (H3-10.0-E / Three Phase Hybrid Inverter)

  • High Efficiency: Max efficiency of 98.00%, Euro efficiency of 97.30% 
  • Dual MPPT Design: Features 2 independent MPPT trackers (2 strings per MPPT on H3-10.0-E), adaptable to complex roof orientations 
  • Wide Input Voltage Range: MPPT operating voltage range of 160-950V, rated input voltage of 720V 
  • Advanced Battery Management: Built-in BMS communication interface (CAN/RS485) for seamless battery integration 
  • High Battery Efficiency: Max battery charge efficiency of 98.5% (PV to Battery) and discharge efficiency of 97% (Battery to AC) 
  • EPS Emergency Backup: Supports Emergency Power Supply output in off-grid mode with <20ms switch time 
  • IP65 Full Protection: Natural convection cooling for H3-5.0 to H3-8.0 models; fan cooling for H3-10.0 and above 
  • Wide Operating Temperature: -25℃ to +60℃ operating range (derating at 45℃) 
  • Complete Protection Features: Includes insulation monitoring, residual current monitoring, DC reverse polarity protection, anti-islanding protection, AC short-circuit protection, DC Type II and AC Type II SPD
