Commercial storage systems are all the rage

Commercial storage systems are all the rage

storage goes commercial – we’ve been following this trend for over 1 year, the recent Intersolar making it perfectly clear that more and more manufacturers are targeting this development.

The big question here: What requirements do commercial storage systems fulfil and what questions need to be asked during meetings with end customers?

Large storage systems are exciting not only because of their traditional functions like providing energy. It’s above all extra features like peak sharing and the supply of control energy that make the use of large storage systems interesting, while offering huge savings potential.

We’d like to present three variants in comparison here – because there’s always the right solution for any customer or any challenge!

The basic variant

The SMA Sunny Island solution in combination with the battery manufacturers BYD or Axitec is the neatest option when it comes to supplying and saving energy pure and simple. The Sunny Island clusters allow the systems to be dimensioned with any size in respect to charging and discharging capacity and performance.



Advantages at a glance:

  • Energy costs reduced immediately and long-term
  • Transparency regarding how energy flows are optimised
  • Independence from the electricity supplier thanks to models for self-consumption optimisation


The advanced variant

The new energy storage system from SMA is primarily intended to save electricity costs with its “Time of Use” function”, enabling load peaks to be capped. The targeted use of battery energy, for instance when tariffs are high or when peak power is required at short notice, enables the high tariffs of supply utilities to be bypassed easily.

Advantages at a glance:

  • Increased self-consumption
  • Storage of surplus PC electricity and consumption at a later time
  • “Time of Use” function (high tariffs/low tariffs)
  • Charging the storage system when electricity prices are low
  • Use of the stored energy when electricity from the supply utility is very expensive
