Lusty and Blundell Limited - Omaha Beach Three Phase Solar Install
Greg Theron, March 12, 2024
Key Requirements:
• Priority to have backup power for notoriously unstable Warkworth Power Grid.
• Save money by using power more efficiently (prioritise high draw loads during sunshine hours).
• Inject any excess generation back into the grid for rebate.
• High priority on aesthetic and discretion of solar panels to ensure the installation was suitable for the neighborhood
High Level Design:
• 3-Phase system with 5kW per phase.
• All loads in the house apart from the 7.2kW EV Charger are on the backup circuits.
• Node red programming to automatically drop the 3-phase swimming pool and spa pool heater during an outage and turn it back on after the grid has recovered.
• 20kWh of lithium batteries (2 x 200Ah @ 51V)
• 4 solar strings @ 390V providing a total of around 9.5kW of solar generation
