Grid Connect Solar System

What Is a Grid Connect Solar System?

A grid connect solar system is a solar PV system that works alongside the electricity grid. It allows you to generate your own power during the day while drawing from the grid when needed. It’s the most common and cost-effective system type in Australian homes.

Connection Types & System Sizes

As a rule of thumb, every home has either a single-phase or three-phase power connection. There are some rare exceptions in unique or older installations, but most properties follow this rule.

Single-phase homes are the most common and have one 15kVA line coming into the property.
Three-phase homes have three 15kVA lines, offering more power capacity — ideal for larger homes or properties with high energy demands like ducted air conditioning or EV chargers.

If you’re not sure which one you have, don’t worry — we’ll check it for you during your quote process.

What Size Solar System Can I Get?

Your connection type impacts what size solar system you’re allowed to install. At JVC Energy, we always maximise your solar capacity in line with your network’s requirements and energy profile.

Single-Phase
Typical Use: Most homes
System Limit: Up to 10kVA inverter (approximately 13kW of solar panels)

Three-Phase
Typical Use: Larger homes & rural properties
System Limit: Generally no limit, may have export limitations (depending on network approval)

We design your system based on your energy usage, connection type, and the guidelines of your local electricity distributor.

Inverter Topology

The inverter is the core component that converts the solar electricity (DC) your panels generate into usable electricity (AC) for your home. Choosing the right inverter is essential for ensuring your system is reliable, efficient, and suitable for future upgrades.

String Inverter
Most common inverter type. Most inverter brands have advanced maximum power point tracking and intelligent power production minimising the impact of shading.

Hybrid Inverter
Designed to work with both solar panels and batteries, either now or in the future. A great option if you're planning to add energy storage or want backup capability for blackouts.

Microinverters or Power Optimisers
Ideal for roofs with multiple angles or partial shading.
Each panel operates independently, improving efficiency and allowing detailed system monitoring.

PV Oversizing & STC Limits
When designing your solar system, there’s often an opportunity to install more panel capacity than the inverter’s rated output—this is called “PV oversizing.” It’s a smart way to boost energy generation, particularly during early morning and late afternoon when sunlight is less intense.

PV Oversizing Guidelines
According to Clean Energy Council guidelines, panels can be oversized up to 133% of the inverter’s AC capacity.
For example, a 5kW inverter can support up to 6.66kW of solar panels.
STC Rebate Implications
Small-scale Technology Certificates (STCs) are government rebates that reduce your system’s upfront cost.
The amount of STCs is based on panel capacity, installation location (zone), and the year of installation.
To qualify, systems must meet strict installation standards and oversizing limits.
Why Oversize?
Oversizing can improve system output during lower solar hours, reduce payback time, and ensure your home captures more usable energy throughout the day—without needing a larger inverter.

Who Can Install Grid-Connected Solar?

In Australia, only Solar Accreditation Australia (SAA) accredited installers are authorised to install and commission grid-connected solar power systems. Choosing a qualified installer ensures your system complies with safety regulations, performs efficiently, and remains eligible for manufacturer warranties and government rebates.

JVC Energy provides:

Licensed, SAA-accredited solar electricians

ISO-compliant quality, environmental, and safety systems

More than 15 years of solar installation experience across diverse regions

Grid Connect Solar System with Battery Storage

Grid-connected solar with battery storage offers the best of both worlds—daytime energy savings and nighttime energy security. With the rising cost of electricity and growing interest in energy independence, solar battery systems are now a popular upgrade to standard grid-tied setups.

A solar battery system stores unused solar energy produced during the day for use in the evening, or when solar production is low. It reduces reliance on the grid, offers blackout protection, and provides backup power during outages.

Whether you're looking to lower energy bills, gain energy independence, or protect your home from blackouts, JVC Energy offers expertly engineered battery-ready solar systems tailored for residential and commercial use across NSW, VIC, and QLD.

Backup Load Options – Whole of House or Selected Loads

When adding battery storage, one of the first decisions is what part of your home should stay powered during an outage. There are two main options:

Selected Loads Backup
This is the most common setup. A dedicated backup circuit is installed to power essential appliances such as:
Fridge/freezer
Lighting
Internet/router
Fans
Power points for charging and communications
This approach keeps battery size and cost lower, while ensuring key areas of the home remain operational during a blackout.

Whole-of-House Backup
This option powers your entire property from the battery. It requires:
A larger battery system
Inverter capacity that can meet the full household load
Careful design to avoid system overload
Whole-of-house backup is ideal for larger homes or those in blackout-prone areas who want full energy continuity.

A determining factor as to what configuration you can have will be based solely on the Hybrid Inverter that you choose.

PV Oversizing Requirements with Batteries & STC Eligibility

Oversizing your solar array—installing more solar panel capacity than your inverter’s nominal output—has become a strategic design choice in grid-connected battery systems. At JVC Energy, we incorporate oversizing to improve system efficiency, performance in both solar and battery components while ensuring compliance with Australian Standards.

Why Oversize?

Inverter Efficiency Improves at Higher Input Voltages:
Most inverters operate at their highest efficiency when the solar array is producing close to their maximum input. Oversizing ensures your inverter spends more of the day in its optimal performance range.

Faster Battery Charging:
By generating more power earlier in the day and later in the afternoon, your battery charges more rapidly and fully—especially valuable in winter or cloudy conditions.

Maximised Solar Harvest:
Oversized systems produce more energy overall, even if the inverter occasionally clips excess generation. This means better self-consumption and energy independence.

Increased ROI:
Increased solar capacity allows the system to generate more STC's reducing the initial capital expenditure.

STC Rule Change When Oversizing with a Battery Connected

When you add a battery to your solar system, the standard 33% oversize rule for STCs no longer applies.

You can now oversize up to the inverter’s maximum DC input capacity, which is often 50% to 100% higher than the inverter's nominal AC output. This means a 5kW inverter may legally support up to 7.5-10kW of solar panels—and still be eligible for full STC rebates, provided the system meets Clean Energy Regulator guidelines.

The ability to oversize further allows more flexible design and better system performance without forfeiting financial incentives.

NSW PRC Rebate: What You Need to Know

In New South Wales, households installing solar and battery systems can access additional financial benefits through the Peak Demand Reduction Scheme (PDRS). This scheme rewards systems that help reduce demand on the grid during peak times—particularly in summer.

A Peak Reduction Certificate (PRC) is a tradable certificate issued when a system demonstrates measurable reduction of peak electricity demand. These are typically generated through:

Solar battery systems that discharge during peak hours

Smart system management with load shifting or discharge scheduling

Ongoing monitoring and compliance with scheme guidelines

Stand Alone Power Systems

Stand Alone Power Systems—also known as off grid solar systems—provide complete energy independence without any connection to the electricity grid. Ideal for remote properties, rural farms, and lifestyle blocks, these systems are designed to generate, store, and manage all your power needs on-site.
