Solar PV main switchboards
Solar PV systems need a switchboard that connects the inverters safely to the building or grid supply, with the right protection and metering. We build PV switchboards for solar EPC contractors and asset owners.
Typical applications
- Commercial and industrial rooftop solar
- Ground-mounted solar farms
- Self-consumption and export schemes
Engineering and customisation options
- Inverter incomers and AC combining
- Protection and isolation to your design
- Import and export metering
- Integration with the existing main switchboard
- Indoor or weatherproof designs to suit the installation site
- A choice of forms of separation (Form segregation ratings) to your specification
Standards and certification
Built to IEC 61439 where your specification requires it. Our ASTA type certificates cover 2000A, 3200A and 4000A assemblies; ask us which tested design applies to your board.
Lead time, warranty and brands
- Typical lead time
- Confirmed with your quotation

How it is built and tested
- Design and drawings. We review your single-line diagram and specification, then issue general arrangement and wiring drawings for approval.
- Sheet metal fabrication. Enclosures are laser-cut, sheared and bent in-house, so we control dimensions and lead time.
- Powder coating. Enclosures are powder coated in our own spray booth for a durable, even finish.
- Assembly and wiring. Busbars, breakers, metering and control wiring are assembled to the approved drawings.
- Testing and inspection. Boards are inspected and tested before they leave the factory, then commissioned on site.
