Home Battery Installation Melbourne
SAA accredited battery storage installation for Melbourne homes and businesses. Store your solar energy, slash your electricity bills, and keep the lights on during outages. Carlin Co Electrical is your local specialist for home battery systems that actually perform.
Melbourne electricity prices continue to climb while solar feed-in tariffs sit as low as 3.3c/kWh on some retail plans. Without a battery, most of your solar generation is exported for next to nothing and you buy expensive grid power back at peak rates every evening. A properly sized home battery changes that equation entirely, letting you use your own solar energy around the clock and reducing grid dependence by 70-90%.
As an SAA Accredited Installer (S8099714), Tesla Certified Installer, and NETCC signatory, Carlin Co designs and installs battery systems from all major manufacturers including Sigenergy, Tesla Powerwall, Alpha ESS, and myenergi Libbi. Every installation includes professional switchboard work, dedicated backup circuits, full commissioning, and all compliance paperwork handled on your behalf.
How Home Battery Storage Works
A home battery is a rechargeable energy storage system that connects to your solar panels and switchboard, allowing you to capture surplus solar generation and deploy it when you need it most.
Store Excess Solar Energy
Most Melbourne homes generate significantly more solar power during the middle of the day than they consume. Without a battery, this surplus is exported to the grid at minimal feed-in rates. A battery captures that excess energy and stores it for use in the evening and overnight, when your household consumption is typically highest and grid electricity is most expensive.
Maximise Time-of-Use Savings
If your electricity plan uses time-of-use pricing, a battery delivers the greatest savings by discharging during peak and shoulder rate periods (typically 3pm to 9pm on weekdays) when grid electricity costs 35-55c/kWh. The difference between your feed-in rate and your peak usage rate represents pure savings on every kilowatt-hour your battery cycles.
Backup Power During Outages
Most modern battery systems can provide backup power when the grid goes down. During a blackout, the battery disconnects from the grid, forms its own micro-grid, and continues to power your designated backup circuits. With solar panels charging the battery during daylight hours, a well-configured system can sustain essential loads through extended outages. We install dedicated backup switchboards with clearly labelled circuits so you know exactly what is protected.
Virtual Power Plant Participation
Several energy retailers in Victoria offer Virtual Power Plant (VPP) programs that pay battery owners for allowing controlled discharge during grid demand peaks. Programs like Tesla Energy Plan, AGL VPP, and Amber Electric can generate additional revenue from your battery beyond self-consumption savings, further improving payback timelines.
Battery Systems We Install
We are brand-agnostic and recommend the system that best suits your home, energy usage, and budget. Every battery we install is CEC-approved and backed by a manufacturer warranty.
Sigenergy SigenStor
The SigenStor is a modular 5-in-1 system integrating an inverter, battery, EV charger, energy management, and backup power in a single stackable unit. Available in 5 to 48+ kWh configurations using LiFePO4 chemistry, it delivers 98.4% round-trip efficiency and carries an IP66 weather rating with built-in fire suppression. We are experienced Sigenergy installers and can design a system tailored to your home.
Tesla Powerwall 3
As Tesla Certified Installers, we install the Powerwall 3 with its integrated solar inverter and 13.5 kWh usable capacity. Seamless app monitoring, Storm Watch backup activation, and the ability to stack multiple units make the Powerwall 3 one of the most popular residential batteries in Australia.
Alpha ESS SMILE5
A strong value option with 5.7 kWh usable capacity expandable to 34.2 kWh, backed by a 10-year warranty. The SMILE5 suits homeowners looking for a reliable, well-priced battery with solid Australian support and flexible sizing options.
myenergi Libbi
Designed to integrate with the myenergi Zappi EV charger and Eddi hot-water diverter, the Libbi is ideal for households with electric vehicles and solar. It provides smart energy management across your entire home ecosystem, prioritising self-consumption across battery, EV, and hot water loads.
BYD Battery-Box Premium
BYD is one of the world’s largest battery manufacturers, and the Battery-Box Premium series offers modular LFP storage from 5.1 to 25.6 kWh per tower. Compatible with a wide range of hybrid inverters, BYD batteries are known for their build quality, long cycle life, and competitive pricing.

Battery Sizing and Installation Considerations
Choosing the right battery involves more than picking a brand. We assess your energy profile, existing electrical infrastructure, and goals to recommend the optimal system for your household.
Capacity and Power Output
Battery capacity (measured in kWh) determines how much energy you can store, while power output (measured in kW) determines how quickly you can discharge it. A typical Melbourne household uses 15 to 25 kWh per day. For most homes, a 10 to 13 kWh battery covers evening and overnight usage when paired with a well-sized solar system. Larger homes or those with pool pumps, ducted heating, or EV charging may benefit from 15 to 20+ kWh of storage.
Solar System Compatibility
Batteries can be added to most existing solar installations. If your current inverter is a standard string inverter, you will typically need either a hybrid inverter upgrade or an AC-coupled battery system. Systems like the Tesla Powerwall 3 and Sigenergy SigenStor include integrated inverters, simplifying the installation. We review your existing setup during the site assessment and recommend the most cost-effective integration approach.
Single Phase vs Three Phase
Your electrical supply type affects battery selection. Single-phase homes (most Melbourne houses) are compatible with all major battery systems. Three-phase properties require batteries and inverters rated for three-phase operation to ensure proper load balancing and backup functionality across all phases. We handle CT monitoring configuration to optimise energy flows regardless of your supply type.
Indoor vs Outdoor Mounting
Most modern batteries carry IP65 or IP66 ratings and can be installed outdoors, though performance is best when operating temperatures are moderate. We assess your property for the optimal mounting location, considering factors such as cable runs to the switchboard, ventilation, direct sun exposure, and clearance requirements specified by the manufacturer and AS/NZS 5139.
Rebates and Incentives
The federal Cheaper Home Batteries Program provides a point-of-sale discount of approximately $372 per kWh on eligible battery installations, meaning a 10 kWh battery receives roughly $3,720 off the installed price. Carlin Co is a registered installer under this program and applies the rebate at the point of sale, so you receive the discount upfront. Combined with VPP program payments and time-of-use savings, batteries are now more financially viable than ever for Melbourne households.
