Important Note (UK Installation Requirements):

In the UK, wiring regulations require that the STREAM microinverter must be connected to your home’s electrical system via a fused spur using a DIY cable (choose the second option in this listing). The cable and corresponding circuit at your fuseboard must carry a warning label stating that the microinverter must be disconnected to safely isolate the circuit. Installation must be carried out by a qualified electrician. Please contact us if you need assistance arranging this.
