Commercial Battery Storage Kits

Bookmark and Share

For larger electricity consumers the addition of an energy storage system can in many cases enable savings based on:

  • Standard Metered Billing
  • DUoS Charges (Basic / Red / Amber / Green)
  • TNUoS Charges
  • TRIAD Charges
  • Climate Change Levy

In combination with export limitation it can also enable installation of larger PV systems onto weak grid connections and allow greater self-consumption of own generated PV power.

In addition, the ability of systems that can provide back-up to essential circuits in the event of a power cut can give immediate benefits for many businesses.
