The start-up

VoltStorage SMART is the safest, most durable and most environmentally friendly power storage system available for private households with PV systems.

The need

A photovoltaic system generates solar power – but only when the sun is shining. In order to optimise utilisation of solar energy it is necessary to find a solution that can temporarily store the self-produced surplus solar power in an efficient, cost-effective and secure way.

The solution

Unlike conventional storage solutions made of lithium and lead-sulphuric acid, VoltStorage’s solar power battery system is not only less expensive and more durable, but it also offers enhanced safety in domestic use and ecologically sustainable production: the recyclable vanadium electrolyte used for the battery consists mainly of pure water and is therefore not flammable or explosive, even under extreme conditions or in the case of malfunctions.

The value proposition

  • 100% capacity guarantee.
  • All-in-one system.
  • Fully recyclable.
  • Long lasting.
  • Non-flammable.
