7kW Three-Phase Solar Installation in Putney, Sydney

MPV Solar completed a 7.77kW residential solar installation for a home in Putney, Sydney.

The system combines 21 × 370W Jinko solar panels with a 6kW Fronius Symo three-phase inverter, creating a residential solar system designed around the property’s electrical supply and household energy requirements.

The three-phase inverter is an important part of this project, demonstrating why residential solar design should consider not only the number of panels being installed, but also the home’s existing electrical infrastructure.

Location: Putney, Sydney NSW
Area: Ryde / Northern Sydney
Project Type: Residential Solar Installation
Solar System Size: 7.77kW
Solar Panels: 21 × Jinko 370W
Inverter: 6kW Fronius Symo
Electrical Configuration: Three-Phase
System Type: Residential Rooftop Solar

For this Putney property, MPV Solar installed 21 Jinko 370W solar panels, creating a total rooftop solar capacity of 7.77kW.

The array was paired with a 6kW Fronius Symo three-phase inverter.

Residential solar design involves more than deciding how many panels will fit on the roof.

MPV Solar considers factors such as:

• Household electricity consumption
• Available roof space
• Roof orientation
• Shadin
• Existing electrical supply
• Single-phase or three-phase power
• Inverter requirements
• Future battery storage
• EV charging plans
• Future household electricity demand

before recommending an appropriate system.

For local homeowners, MPV Solar provides residential solar installation in Putney as part of its wider Sydney solar service area.

The project involved a residential property in Putney, NSW.

The completed solar system includes:

• 21 × Jinko 370W solar panels
• 7.77kW total solar panel capacity
• 6kW Fronius Symo inverter
• Three-phase inverter configuration
• Residential rooftop solar generation

The system demonstrates how solar panel capacity and inverter configuration can be designed around the electrical infrastructure of the individual home.

This Putney installation uses a Fronius Symo three-phase inverter.

Homes can have either single-phase or three-phase electricity supplies, and the existing supply is an important consideration when designing a solar system.

Three-phase power distributes electricity across three active phases and is often found in homes with higher electrical requirements.

Depending on the property, three-phase supply may support loads such as:

• Larger air-conditioning systems
• Pool equipment
• Electric cooking
• Home workshops
• Battery systems
• EV chargers
• Other higher-demand electrical appliances

It can also influence how the solar inverter and broader electrical system are configured.

7.77kW Jinko Solar Panel System

MPV Solar installed 21 × 370W Jinko solar panels, providing a total rooftop solar capacity of 7.77kW.

The panel array forms the generation component of the system and was designed around the requirements of the Putney property.

The right solar system size for another home may be very different depending on electricity consumption, roof space, shading, electrical supply and future energy requirements.

6kW Fronius Symo Three-Phase Inverter

The solar array is paired with a 6kW Fronius Symo three-phase inverter.

The inverter converts the DC electricity produced by the rooftop solar panels into AC electricity suitable for use within the home.

The Fronius Symo range is designed for three-phase electrical systems, making the property’s existing power supply an important part of the overall solar design.

MPV Solar is experienced with Fronius inverter technology and provides more information about its range on the Fronius solar products page.

It is possible for the rated capacity of a rooftop solar-panel array to be higher than the AC rating of the inverter.

Solar panels rarely operate at their laboratory-rated maximum output continuously throughout an entire day because generation changes with factors such as:

• Time of day
• Season
• Panel temperature
• Roof orientation
• Shading
• Weather conditions

Solar designers can therefore configure panel capacity and inverter capacity differently rather than simply matching the two numbers exactly.

Whether this approach is suitable depends on the individual inverter, system design, electrical supply and applicable connection requirements.

For this Putney project, 7.77kW of Jinko solar panels were paired with a 6kW Fronius Symo inverter as part of the completed system configuration.

The completed Putney installation provides the property with:

• 7.77kW of rooftop solar capacity
• 21 × Jinko 370W solar panels
• 6kW Fronius Symo inverter
• Three-phase solar configuration
• A residential solar system designed around the individual property

The project demonstrates why the electrical supply of a home should form part of the solar assessment from the beginning.

Panel capacity, inverter selection and existing electrical infrastructure all need to work together as part of the complete system.

Homes across Putney and the surrounding Ryde area can vary significantly in age, roof design, electrical supply and household energy requirements.

Properties across Putney, Ryde, Gladesville, Tennyson Point, North Ryde, Eastwood, Hunters Hill and surrounding suburbs may have either single-phase or three-phase power and very different electricity consumption profiles.

The right solar system therefore depends on the individual property.

MPV Solar can assess:

• Household electricity consumption
• Available roof area
• Roof orientation
• Shading
• Existing electrical supply
• Single-phase or three-phase power
• Switchboard configuration
• Battery plans
• EV charging requirements
• Future household energy use

before recommending an appropriate system.

MPV Solar also provides solar services across Sydney, including Putney, Ryde and surrounding suburbs.

Whether a home has single-phase or three-phase power can become increasingly important as household electricity requirements grow. A home may eventually incorporate:

• Battery storage
• An electric vehicle
• Home EV charging
• Induction cooking
• Electric hot water
• Additional air conditioning
• Pool equipment
• Other high-demand electrical appliances

That is why MPV Solar considers the existing electrical supply as part of the wider home-energy picture rather than treating rooftop solar as an isolated product.
