Hybrid Inverters & Smart Energy Management

A hybrid inverter is the brain of a modern solar and battery system. Unlike standard solar inverters, hybrid models manage solar generation, battery charging and discharging, grid interaction, and backup power all from a single unit. This simplifies installation, reduces costs, and provides a single monitoring interface for your entire energy system.

We install hybrid inverters from Fronius (Gen24), Sungrow, Goodwe, Huawei (SUN2000), and Sigenergy. Each platform has distinct strengths, and our recommendation depends on your specific requirements for backup capability, battery compatibility, and monitoring preferences.

What does a hybrid inverter actually do?

A hybrid inverter handles four key functions: converting DC power from your solar panels to AC for household use, managing battery charging from solar or grid power, providing seamless backup during grid outages, and optimising energy flows to minimise your electricity costs. Some hybrid inverters, like the Fronius Gen24, also include integrated EV charging capability.

three-phase Solar Systems

Many Melbourne homes, particularly newer builds and properties with ducted air conditioning, pools, or EV chargers, operate on a three-phase power supply. Three-phase solar requires specific inverter selection and configuration to balance generation across all phases and comply with distributor requirements.

Carlin Co’s electricians are experienced with three-phase installations across all Melbourne distribution networks, including CitiPower, Powercor, Jemena, AusNet, and United Energy. We handle the connection application, meter configuration, and commissioning to ensure your system exports and imports correctly across all three phases.

If your property requires a switchboard upgrade to accommodate solar, we can complete this as part of the installation, saving you the cost and disruption of engaging a separate electrician.

Solar for Apartments & Strata Properties

Installing solar on apartments and strata properties in Melbourne presents unique challenges around shared infrastructure, body corporate approvals, and metering arrangements. Carlin Co has experience navigating these complexities and can help strata committees evaluate options including common-area solar systems, individual unit installations, and embedded network configurations.

Common-area solar systems offset electricity used by lifts, lighting, car park ventilation, and other shared services, reducing owners’ corporation levies. For individual units with dedicated roof access, we can design and install systems connected to your private meter. In both cases, we prepare the technical documentation required for body corporate approval and manage the entire process from proposal through to connection.

Virtual Power Plant (VPP) Enrolment

A Virtual Power Plant connects your home battery to a network of other batteries, collectively providing grid stability services and earning you credits or payments. By enrolling in a VPP program, your battery can discharge small amounts of stored energy during peak demand events, generating income from an asset that would otherwise sit idle during those periods.

We configure and enrol battery systems in VPP programs from Tesla (Tesla Energy Plan), Amber Electric, and Simply Energy, among others. VPP participation is entirely optional and typically involves your battery contributing 1-2 hours of discharge per event, with most households barely noticing the impact while earning meaningful credits on their electricity bills.

Government Rebates & Incentives

Several government programs can significantly reduce the cost of solar and battery installation for Melbourne homeowners. Our team stays across the latest program changes and handles the rebate application process as part of your installation.

Victorian Solar Homes Program

Eligible Victorian households can receive up to $1,400 off a solar PV system, plus a matching interest-free loan. Owner-occupiers of existing properties with a combined household income under $150,000 per year can apply through Solar Victoria (the cap was reduced from $210,000 on 1 July 2026). The property must also be valued under $3 million. Carlin Co is an approved installer under this program.

Small-scale Technology Certificates (STCs)

Every solar installation generates STCs based on system size and location, which provide an upfront discount typically worth $2,500 to $4,500 depending on your system size. This federal incentive is automatically applied at the point of sale, reducing your out-of-pocket cost on the day of installation.

Federal Battery Incentives

The federal government’s focus on home battery adoption has expanded incentive pathways for battery storage. Eligible households can access meaningful upfront discounts on battery installation costs. We help you navigate the available programs and ensure your system qualifies for maximum savings.

Victorian Solar Homes Income Cap: Now $150,000

From 1 July 2026 the combined household income eligibility cap for the Victorian solar PV rebate decreased from $210,000 to $150,000 per year. Applications submitted after 30 June 2026 are assessed under the $150,000 cap. If your household income is above $150,000 you are no longer eligible for the state rebate, but you can still access federal STCs on solar and the federal Cheaper Home Batteries Program on battery storage. Call us on 0432 632 346 to check what you qualify for. Verified 1 August 2026.

Grid Connection & Export Limiting

Connecting a solar system to the grid in Melbourne requires approval from your local electricity distributor. The process involves submitting a connection application, installing compliant metering, and configuring your inverter to meet the distributor’s export and voltage requirements.

Some Melbourne distribution networks impose export limits, particularly for larger systems or in areas with high solar penetration. Common limits include 5kW per phase for single-phase connections and 5kW per phase for three-phase systems. Where export limiting applies, adding battery storage allows you to capture excess generation that would otherwise be curtailed, improving your system’s financial return.

Carlin Co handles the entire connection process for you, from the initial application through to final commissioning and meter exchange coordination. We lodge applications with CitiPower, Powercor, Jemena, AusNet, and United Energy, and our familiarity with each distributor’s requirements helps avoid delays and rejected applications.

Solar System Maintenance

A well-maintained solar system will perform at peak efficiency for 25 years or more. While solar panels have no moving parts and require minimal upkeep, regular inspections ensure your system continues to generate at its rated capacity and that all safety systems remain functional.

Our maintenance services include panel cleaning, inverter health checks, DC isolator inspections, cable and connector integrity testing, monitoring system audits, and performance benchmarking against expected output. We recommend a professional inspection every two years, or annually for systems over five years old.

If your existing solar system is underperforming, our electricians can diagnose issues including panel degradation, inverter faults, shading impacts, soiling, and connection problems. We service all brands and can upgrade components like inverters where this makes economic sense.

Solar and Battery Installation FAQs

How much does a solar panel system cost in Melbourne?

A standard 6.6kW residential solar system in Melbourne typically costs between $4,500 and $6,500 fully installed, after STC discounts. Larger systems of 10-13kW range from $7,000 to $13,500. These prices include Tier 1 panels, a quality inverter, professional installation, and all compliance documentation. The Victorian Solar Homes rebate of up to $1,400 can reduce this further for eligible households.

Is a home battery worth it in Melbourne?

For most Melbourne households, a home battery becomes financially worthwhile when you have high evening energy consumption and are on a time-of-use tariff. A battery allows you to use stored solar energy during the expensive peak period (typically 3pm to 9pm) rather than buying from the grid. With current electricity prices and battery costs, payback periods typically range from 7 to 12 years, with the battery providing additional value through backup power and VPP income. As electricity prices continue to rise, payback periods are shortening.

What solar rebates are available in Victoria in 2026?

Victorian homeowners can access the Solar Homes Program rebate of up to $1,400 for solar PV systems, available to owner-occupiers with a combined household income under $150,000 (reduced from $210,000 on 1 July 2026). All solar installations also benefit from federal Small-scale Technology Certificates (STCs), which provide an upfront discount of $2,500 to $4,500 depending on system size. Battery installations may qualify for the federal Cheaper Home Batteries Program, an Australian Government scheme. The Victorian Solar Homes battery rebate closed on 30 June 2023.

How long does a solar and battery installation take?

A standard residential solar installation is completed in one day. If a battery is being installed at the same time, the installation typically takes one to two days. The full process from quote acceptance to energisation, including distributor connection approval and meter exchange, usually takes three to six weeks. We manage the entire timeline and keep you updated at every stage.

Do I need to upgrade my switchboard for solar?

Many older Melbourne homes require a switchboard upgrade before solar can be installed. If your switchboard still uses ceramic fuses or does not have adequate space for solar protection devices, an upgrade will be required to meet current safety standards. As licensed electricians, we assess your switchboard during the site visit and include any necessary upgrades in your quote, saving you the hassle of coordinating a separate tradesperson.

What is the best battery for a Melbourne home?

The best battery depends on your specific requirements. The Tesla Powerwall 3 offers 13.5kWh storage with an integrated inverter and excellent backup capability. Sigenergy is ideal for larger capacity needs with its modular design scaling to 48kWh+. BYD Battery-Box provides great value and broad inverter compatibility for retrofit installations. Enphase IQ Battery suits homes already using Enphase microinverters. We recommend the right solution based on your energy profile, backup needs, and budget during a free consultation.

Can I install solar on my apartment or townhouse?

Yes, solar can be installed on apartments and townhouses in Melbourne, though the process involves additional considerations. You will need body corporate approval, and the installation must comply with strata regulations. For units with dedicated roof access, individual systems connected to your private meter are straightforward. For common areas, shared solar systems can offset building electricity costs. We prepare all technical documentation and can present to your owners’ corporation committee to support the approval process.

What happens to my solar system during a power outage?

A standard grid-connected solar system without a battery will shut down during a power outage for safety reasons. This is a regulatory requirement to protect line workers. If you have a battery with backup capability (such as Tesla Powerwall or Sigenergy), your system can automatically disconnect from the grid and continue powering your home using stored energy and ongoing solar generation. We configure backup circuits during installation so your essential loads, such as lighting, refrigeration, internet, and selected power points, remain powered during outages.

How do I choose between a string inverter and microinverters?

String inverters (like Fronius or Sungrow) are cost-effective and well-suited to roofs with consistent orientation and minimal shading. Microinverters (Enphase) are installed behind each panel and offer panel-level monitoring and optimisation, making them ideal for complex roof layouts with multiple orientations or partial shading. Microinverter systems also eliminate the single point of failure that a central inverter represents. We assess your roof and recommend the most suitable technology during the design phase.

Will solar panels damage my roof?

When installed correctly by qualified professionals, solar panels will not damage your roof. We use engineered mounting systems with flashing kits on tile roofs and appropriate brackets on metal roofs to maintain weatherproofing. Our installers are trained in safe roof work practices and take care to avoid stepping on tiles or causing damage during installation. We also check your roof condition during the site assessment and will advise if any repairs are needed before panels are installed.
