Is there anything specific that I should be asking/telling the installer.

Hello,

That is a top spec, flagship configuration, and you'll be very pleased with it.

The most common issue I've seen recently is when the installer doesn't use the IP-rated plug ends for the wire between the inverter and the battery when it's being installed outdoors. If indoors it's not required but if outdoors, make sure the coms cable is using the included weather-proof connection.

Also, make sure you ask the installer to install the latest inverter and battery firmware as this is often overlooked.

I did a video on it here:

Thanks Will, much appreciated.
