Tesla vs. Enphase: The 2024 Guide to Solar Batteries in Australia

As of 2024, Tesla and Enphase are leading contenders in the solar battery market in Australia. Both brands offer lithium-based batteries, with comparable costs and features. As the demand for solar solutions and electric vehicles grows, these batteries have become crucial for homes seeking energy independence and efficiency. As leading solar providers in Melbourne, we have access to both brands and can install either at your home. The Enphase battery hit the shores of Australia in 2023 and has been highly sought after as the rival to the more well-known Tesla solar battery. Enphase is a lithium-ion battery that differs from Tesla’s, yet both will have a comparable price.


Functionality of Solar Batteries


Solar batteries store energy from solar panels for use when the sun isn’t shining. This storage capability significantly lowers electricity bills and provides power during outages or low sunlight conditions. Typically installed in locations like garages or near electricity boxes, these batteries can adapt to various settings, including outdoor installations. Solar Victoria advises solar panels to save on average $1,000 per year for households and adding a solar battery adds another $1,000 savings. The payback period is a little longer for batteries as they cost more, but if you think over 10 years you are slashing $20,000 off your bills it makes it worth it!


Battery Life and Maintenance

Both Tesla and Enphase batteries come with a 10-year warranty, extendable by another 5 years for an additional cost. Regular maintenance, recommended biennially, can further prolong their lifespan. This includes panel cleaning and system inspections. It is recommended that a solar maintenance inspection be done every 2 years which includes cleaning the panels and inspecting the electrical and battery. As far as battery life is concerned, both brands offer equal longevity.


Safety Standards


Both batteries meet high safety standards and must be installed by certified electricians. Installation considerations include height placement away from pets and children, concealed wiring, and secure wall mounting.

Battery Capacity

Tesla: Offers 13.5kWh storage capacity.

Enphase: Features a modular design with up to 4x5kWh capacity per phase.

Both batteries can be used to supply electricity during a blackout and they can also be employed to power part of a home’s daily energy needs, cutting down on electricity bills. Furthermore, they both silently manage load shifting & releasing energy like a shock absorber when the sun sets, which reduces the amount of power being pulled from the grid and enables the user to take advantage of peak rate times at 35-45 cents instead of exporting at a lower rate of 5-10 cents.


Battery Chemistry and Efficiency


Enphase: Uses lithium iron phosphate, known for safety due to lower risk of thermal runaway.

Tesla: Employs nickel manganese cobalt chemistry for higher efficiency and power, with built-in overheating prevention.

Battery chemistry probably won’t be your deciding factor as it’s not high on people’s list of questions, but we can give you advice on what battery chemistry means and answer any questions you have regarding it. 


Adaptability to Weather Conditions


The Enphase battery boasts a noteworthy attribute that can detect impending weather and then allocate energy accordingly to be prepared for extreme weather or storms. Moreover, it is still capable of taking in additional power in intense conditions. The Tesla battery, on the other hand, is designed to endure any type of weather, being water-resistant. So, they are both able to sustain extreme weather; however, the Enphase has a benefit with its weather-detection and energy-prioritising feature.


Cost and Installation Lead Time


As of 2024, both batteries are priced at around $16,000, including installation. The industry-wide lead time for installation is now approximately 3 months for both Tesla and Enphase, showing an improvement over 2023.
