How 16.64kWh GoodWe Battery Upgrade For an Existing Solar System In Williamstown
At Green Electric Solutions, our technical team works closely with homeowners to understand their energy consumption, existing solar system, and daily electricity needs before recommending a suitable battery. For this Williamstown property, the home already had rooftop solar panels, so we assessed how additional storage could help make better use of solar-generated electricity beyond daylight hours.
Based on the system requirements, we installed two GoodWe Lynx D G2 battery modules, providing 16.64kWh of nominal capacity and 16kWh of usable storage, paired with a 5kW hybrid inverter. Our approach focuses on matching battery capacity to household needs, ensuring homeowners can make informed decisions about energy storage, system compatibility and potential long-term savings.

How We Safely and Professionally Installed a 16.64 kWh GoodWe Battery and Hybrid Inverter in Williamstown
At the Williamstown property, our installers fitted a 16.64kWh GoodWe battery alongside a 5kW hybrid inverter, mounted on a concrete wall in a secure, ventilated space. The battery connects to the inverter through dedicated DC cabling, and the inverter ties into the main switchboard through a new protected circuit. We installed a weatherproof isolator beside the switchboard, so the system can be safely shut down for maintenance or emergencies.
A smart energy meter was added to track household usage and solar export in real time. Everything is clearly labelled with the required “ES” energy storage and “PV” solar identification, plus compliance warning signs, so future electricians and emergency crews know exactly what is installed. All work was tested and commissioned to Australian standards.
