Electrical
-
Please provide photos of the proposed inverter location Note: The inverter should be located in an area that considers the following factors: 1) close to panels for minimal DC cable length 2) In an area easily accessible by both engineers and the client should something go wrong 3) In an area where a cable run to the main fuseboard is easy. If no hard wall or gables in the loft, a back board can be fitted to any truss rafters to mount the inverter. Add any relevant information as a 'Note'

Please take a photo of the ethernet sockets on the back of the router (here we need to identify if there is a spare ethernet socket)
-
Please take a photo of any electrical plug sockets in the immediate vicinity of the router (ensuring the router is in the photo to give perspective) Note: We may need to install extra equipment at this location which will require plugging in. Such as a Powered Network switch or powerline adapter
-
An ethernet cable will need to run from the router location to the battery. Please describe this route and the approximate length of cable. Note: Should cable length be excessive, our installers can use powerline adapters such as TP links) for a 'wireless' connection.
-
Is there a wifi signal at the proposed inverter location?
