iStoragE3 12K 3F Kehua Hybrid Inverter

Product number: ISTORAGE3 12K
Product information "iStoragE3 12K 3F Kehua Hybrid Inverter"

The iStoragE3 inverter is a unit that, together with the iStoragE B5-S2 battery set, creates a modern, safe, and highly efficient iStoragE3 Residential Energy Storage System.

The iStoragE3 power bank is a complete energy storage system that includes one three-phase hybrid inverter and 1 to 8 high-voltage lithium-ion batteries. It was designed for households and storing electricity produced by PV installations or taken from the electric system. The iStorageE system can work in on-grid and off-grid modes and provides the possibility of complete control over power export. It also has direct impact on effectively increasing self-consumption. 

Together with PV modules, the device automatically stores excess solar power during the day for later use. An additional advantage is an ability to set the charging and discharging time, when using the electric system, for consumers using time tariffs, so that they can initially charge the batteries when the energy price is low, and save energy when the price from the electric system is high.

The Kehua iStoragE3 provides remote management and monitoring of energy consumption and export, thanks to the WiseSolar Plus app using a dedicated energy meter. It can operate as a power supply supporting device, providing uninterrupted protection during a malfunction of the electric system or work in an off-grid system with an energy generator, e.g. in the form of a PV installation or an electric power generator, to ensure power independence.

The product's distinctive features:

  • Built-in EMS function with multi-mode operation
  • True uninterruptible power supply, switching time <10ms
  • Physical and electrical dual insulation
  • Modular integration of fire protection
  • AFCI function integration
  • "All in one" design
  • Modular assembly, high-speed plug-in connector
  • Possibility of expansion with numerous batteries (capacity) and many different systems (power)
  • Multi-point monitoring in real-time, SOC adaptive management 
  • Managing batteries at the level of packages, active cell balancing during charging and discharging

ATTENTION! This inverter works only with a dedicated battery module --> iStoragE B5-S2 Kehua
