The iStoragE3 hybrid energy storage system is a modern, safe, and highly efficient power bank by Kehua. The system includes a three-phase inverter and 1 to 8 high-voltage battery modules in the LiFePO4 technology, depending on the required capacity. It has been designed for households and storing electricity produced by home PV systems or collected from the electrical system. The iStorageE3 system can work in an on-gridmode and off-grid and provides complete control over exporting the power. It also directly influences efficiently increasing self-consumption.

When working with PV modules, the system automatically stores excess solar power during the day to be used later. An additional advantage consists in the possibility of setting the charging and discharging time in the case of using the electric system for receivers using time tariffs so that they can initially charge the batteries when the energy price is lower and save energy when its price is higher.

Kehua iStoragE3 provides remote management and monitoring of energy consumption and export, thanks to the WiseSolar Plus app with the use of a dedicated energy meter. It can work as a device for supporting the power supply, ensuring continuous protection during a malfunction of the electric system, or work in the off-grid system with a power generator, for example in the form of a PV system or a generator, to provide power independence.

The product's distinctive features:

  • Built-in EMS function including working in many modes
  • True wireless power supply with a switch time of up to 10ms
  • Physical and electric dual insulation
  • Modular integration of fire protection
  • AFCI function integration (optional)
  • "All in one" construction
