Possible areas
The Grun Blitz Portfolio Home & Small Business is designed for the following application areas. For the task of energy management beyond just day / night shift goes.

  • Single-family homes
  • Multi-family Houses
  • guesthouses and small hotels
  • Public institutions, kindergartens, community centers
  • craft and smaller commercial businesses
  • Farms and rural remote units
  • Complete “island solutions” (with 100% self-sufficient supply)
Ready for the future
High energy densities can be always released unrestrained in extreme cases. Nevertheless, gas, hydrogen, and millions of mobile fuel tanks accepted part of our everyday infrastructure. We trust these systems, “Made in Germany” because research, development, security analysis, standards and continuous quality assurance maximizes the benefits and minimizes the risk have. This procedure also applies to battery storage solutions from Grunblitz.

  • Powerful lithium-ion technology for a lifetime of 20 years
  • Selected cells from renowned manufacturers
  • Compliance with current and future standards and certifications
Solar system without energy storage system Dependence on grid operators

  • Only a small portion of the self-produced PV energy can be directly consumed
  • During periods when no PV power is available, power must be drawn from the public grid
Solar system with energy storage system For your independence

  • The StoraXe® solutions for Home & Small Business store excess PV energy and make it available again when the PV energy supply is insufficient
  • This frees you from rising power prices
Storage of excess energy for time-shifted self-consumption.
Emergency power supply
Provision of power in the event of an interruption of the mains supply.
Primary control power
For the power supply to work everywhere, the grid frequency must always be constant.
Microgrid (Off-Grid)
For a self-sufficient power supply independent of the higher-level power grid.
EV charging
At limited power grid for optimal charging infrastructure.


For centralized and decentralized energy management
From the OFFLINE version of a decentralized single system to complex ONLINE-coupled interconnection systems. With the Grunblitz platform the energy management system is scalable for every application.
