Due to maintenance, Solar Installers will be unable to submit applications through the DER tool from 5pm Friday 17 until 7am Monday the 20 September, 2021. We apologise for any inconvenience this might cause.

Welcome to the online Solar and Battery Connection Tool

This tool is for you if you want immediate approval to install a Solar or Battery system that is:

  • Up to 10kW inverter capacity per phase and 5kW (3.5kW for SWER) total export limit per phase
  • The maximum size that can be catered for through this online tool is 30kW total inverter capacity and 15kW export limit across 3 phases.

Please note: we size all systems based on the total combined inverter rating(s) i.e. both solar & battery inverters, not panel ratings.

Some applications require manual assessment, such as:

  • All systems greater than 30kW capacity and 15kW export
  • Applications that require a more detailed engineering review

There are a few things you'll need before you use this tool:

  • What sort of installation it is, e.g. solar / battery
  • The NMI and meter number of the premise
  • Details of the proposed inverter(s) i.e. manufacturer and model
  • The the installation will be subject to our standard terms and conditions for solar and battery connections.
