Tarneit Solar & Battery Installation: 13.775kW + 48.72kWh

Q: Is 13.775kW of solar the right size for a Tarneit home?

System size depends on household consumption, roof space, and battery pairing. A 13.775kW system suits larger homes with high usage, especially when combined with a large battery. GES assesses each property individually.

Q: What is the FOXESS CQ7 battery and how long will 48.72kWh last?

The FOXESS CQ7-L7 (W) has 48.72kWh of usable capacity. For a household using 20-25 kWh per day, this provides roughly two days of backup storage. Paired with 13.775kW of solar, most load is covered from own energy.

$9,365 Government Solar Rebates: Supporting The Investment

A major aspect of the Tarneit solar and battery installation was the use of Small-scale Technology Certificates (STCs) to reduce the upfront cost. The Job Pack records 81 STCs for the solar PV system and 173 STCs for the battery system, with the homeowner assigning the certificate-creation rights to Green Electric Solutions in return for a monetary discount.

Government Rebates	Rebate Amount
81 Solar STCs × $38.00	−$2,964.00
173 Battery STCs × $37.00	−$6,401.00
Total Rebates	$9,365.00

48.72kWh Battery Storage Built For Energy Flexibility and VPP Capability

Rather than relying solely on solar generation, the Tarneit installation incorporates 48.72kWh of FOXESS battery storage using a FOXESS CQ7-L7 (W) battery system. The documentation records 48.720kWh of both nominal and usable capacity, with the battery installed indoors and connected to the electricity grid as a new battery installation.

This configuration transforms the project from a conventional solar PV system into an integrated solar and battery energy solution, combining onsite electricity generation with substantial energy storage capacity. The battery provides the infrastructure to store available solar energy for use beyond periods of generation, supporting greater flexibility in household energy consumption.

Open switchboard with meter and MCBs, a FoxESS controller display reading MPPT3 output figures, and an external PV/ES combiner/isolator box mounted on the wall.

The installed battery is also documented as Virtual Power Plant (VPP) capable. However, the Job Pack does not confirm that the homeowner is currently enrolled in or participating in a VPP program; it confirms only that the installed battery supports VPP functionality.

The Inverter at the Heart of the System: FOXESS H3-15.0-Smart

The Tarneit system is built around the FOXESS H3-15.0-Smart inverter, documented as an AS4777-2:2020 model and specified across both solar and battery documentation. Installer records confirm the inverter was an approved eligible model and complied with AS/NZS 4777.2:2020 for the grid-connected installation. The PV modules were also documented as approved eligible models. This provides clear, project-specific evidence of the equipment selected and the applicable installation and compliance requirements.

Frequently Asked Questions – Solar & Battery Installation in Tarneit VIC 3029

What solar and battery rebates are available for Tarneit homeowners?

This Tarneit installation claimed 81 solar STCs worth $2,964 and 173 battery STCs worth $6,401 — a combined $9,365 in government incentives applied directly as a price reduction at point of sale. STC values decrease annually as the scheme winds down toward 2030, so earlier installations typically access more certificates. GES manages all STC paperwork and assigns the certificates on your behalf.

Is 13.775kW of solar the right size for a Tarneit home?

System size depends on your household consumption, roof space, and whether you're pairing with battery storage. A 13.775kW system suits larger homes or households with high daytime usage — particularly when combined with a large battery like the 48.72kWh FOXESS CQ7 installed here. GES assesses each Tarneit property individually and designs around your actual usage data.

What is the FOXESS CQ7 battery and how long will 48.72kWh last?

The FOXESS CQ7-L7 (W) is a wall-mounted lithium battery system with 48.72kWh of both nominal and usable capacity. For a typical Victorian household using around 20–25 kWh per day, this provides roughly two full days of backup storage. Paired with 13.775kW of solar generation, the system is designed to cover most of the home's load from its own energy rather than the grid.

Does Green Electric Solutions install solar and batteries in Tarneit VIC 3029?
