The H3 Pro series is an evolution of the successful H3 series and provides energy independence from 10-30 kW. Here are some key features of the H3 Pro series:


  • Power Output: The H3 Pro series is available in power classes ranging from 10 to 30 kW.
  • MPPTs: The H3 Pro series features 3 Maximum Power Point Trackers (MPPTs) for diverse solar-oriented rooftops.
  • DC Inputs: The inverters have high-current DC inputs.
  • Integration: The H3 Pro series is designed to integrate with smart homes and Fox ESS energy management systems.
  • Battery Inputs: The inverters offer a maximum of two battery inputs (2 Ports)* and a vast selection of battery options, enabling customers to expand their capacities up to 66 kWh each by adding 2 stacks of 1 master and 6 slaves ECS batteries.
  • Parallel Configuration: In industrial/commercial mode, several H3 Pro inverters can be configured in parallel, creating a battery system with a maximum capacity of 660 kWh.
  • Emergency Power Supply: The inverters are equipped with a built-in emergency power supply, allowing them to establish an independent grid for emergency power supply within 20ms or less during a blackout or grid disconnection.
  • Plug-and-Play: The H3 Pro series is an easy plug-and-play solution and fits perfectly with Fox ESS high voltage batteries-lines ECS 2800/2900/4100/4300/4800, as well as MIRA and HV 2600 batteries.
  • Communication Options: This series inverter is available with multiple communication options such as WiFi, GPRS, RS485, and Meter with an external device. Operating information like output voltage, current, frequency, fault information, etc. can be monitored locally or remotely via these interfaces.

Overall, the H3 Pro series is a versatile and powerful solution for those looking to achieve energy independence and integrate renewable energy into their homes or businesses.

* Only 25kW+ models have the dual battery ports.
