Electrical works
DC and AC cabling, inverters, transformers, earthing, protection, monitoring and pre charging testing.
DC cabling from modules through combiners, AC cabling to inverters and transformers, inverter and transformer installation, earthing and lightning protection, plant control and monitoring systems, and the testing sequence that has to be completed and documented before the plant can be charged.
What this includes
- DC cabling, combiner boxes and string testing
- AC cabling, inverters and transformers
- Earthing and lightning protection installation
- Plant control and monitoring system commissioning
- Insulation, continuity and polarity testing
- Documented pre charging test records
- What you receiveOutput
- Electrically complete plant with test records, ready for charging
- When you need itTiming
- Following mechanical completion.
Undocumented testing. Utilities and lenders both ask for the records, and repeating the tests on a built plant is slow and expensive.
Delivered by our own team together with vetted specialist partners and, where the question needs it, a named member of our expert bench. We tell you who is doing the work before the engagement starts.
