About this installation
This homeowner in Whangarei was looking for a 7kW three-phase system. The advantages of a three-phase inverter are clear: more stable load distribution, better handling of high-power appliances, higher efficiency in power generation and more flexibility for future system expansion.
The project is upgraded from our 7kW standard home solar package priced at $10,899, with additional upgrades for three-phase power, concrete tile roof installation and extra travel costs for locations outside Auckland.
The array uses 14 x 500W panels. High-efficiency panels, a premium inverter and a fully customised design were specified for long-term performance.
