Will I receive a certificate of completion from the installer/ electrician?

Your solar or battery storage system supplier will usually arrange connection to the network on your behalf, including preparing and submitting all relevant documentation required from the electricity retailer and/or distributor for meter installation and connection to the network.
It is important, however, to be aware of the process involved, who to contact to follow up on progress, and to ensure that everything gets done on time.
Check with your installer what documents you will receive for the battery storage system.
