Commercial plant-room installation with inverters and isolators

Electrical work that holds the system together

Solar, storage and EV charging all depend on the supply and distribution behind them. We design and install that work as part of the same project.

Our electrical team is NAPIT accredited, so the renewable and electrical work is delivered and certified by one contractor.

  • Supply capacity assessed before design
  • Distribution and sub-mains designed around new loads
  • Testing, inspection and certification
  • NAPIT-accredited electrical work
