Bentley Maintenance


Changing brittle MC4 leads. Again, Helios delivered, with all required works completed in time and on budget.

Client: Bentley

Helios were contacted by PSH Operations, with a view to assisting them with some remedial works on the 5MW rooftop system at the Bentley Motors manufacturing facility in Crewe, due to another contractor having let them down. Over 200 inverters. Over 20,000 solar panels. A lot of testing and remedial works required.

Helios were requested to carry out

  • String testing
  • Thermographic images of all inverters
  • Replacement of all inverter MC4’s
  • Replacement of all inverter batteries
  • Adjustment of clock settings
  • Tidy existing cabling
  • Re-labelling of strings and inverters

All the works were required to be carried out during a two-week period when the Bentley factory shuts down. So the timing and co-ordination had to be perfect to be able to meet Bentley’s requirements so that scaffolding that had been erected to allow us to do the works could then be removed to allow the factory to start functioning again at 100% capacity at the end of the 2 week shutdown.

Thermographic images of inverters and the combiner boxes were taken of all inverters.

Tarpaulins needed to be deployed to keep working area dry.
