Battery Storage: Maximise Your Solar Savings & Take Control of Your Energy Independence

Solar panels produce electricity when the sun is up. Your home uses some of that and sells the excess power back to the grid at the prevailing feed-in-tariff. However, at night, power companies charge up to ten times as much as they paid you, to sell power back to you. With a battery storage system, such as Enphase IQ Battery 5P or Tesla Powerwall, you can use the free energy that the sun gave you during the day.

Bundle your 1KOMMA5° solar system with a battery storage and enjoy huge savings. Hurry, available for a limited time only.

1KOMMA5° Enphase IQ Battery
15-year warranty. Installed by experts.

Enphase IQ Battery

The Enphase system has been designed to be modular, expandable, and easily installed. Because the batteries can be cycled multiple times across the day, they can be tailored to each customer’s usage profile. A household or business will be able to monitor their usage, solar generation and peak times, and install more battery capacity knowing that it will pay for itself in the quickest possible time.

Enphase IQ Batteries are connected directly to the meter board, where we install a control hub (the IQ System Controller) that manages power consumption and storage in the home. In the future, this may allow the Enphase IQ Battery to be compatible with any existing solar system – but for now, this exciting new product is only available to customers with Enphase solar systems!

1KOMMA5° Tesla Powerwall
10-year warranty. Easy energy management.

Tesla Powerwall

Tesla Powerwall is a smart home battery system that integrates with your existing solar system and can provide backup power for when the grid goes down.

6 Reasons to Enhance Your Solar System with Battery Storage

1. Energy cost savings

By storing excess energy, you can use it when energy prices are higher, which helps to lower your energy bills and increase your cost savings.

2. Enhanced Energy Independence

An energy storage unit allows you to store excess solar energy for use during times when the sun is not shining. This helps to reduce the amount of energy that you need to purchase from the grid and increases the overall efficiency of your solar system.

3. Enhanced Sustainability

By reducing your dependence on the grid and utilizing renewable energy, you can help to reduce your carbon footprint and contribute to a more sustainable future.

4. Increased Solar Panel Performance

Store excess solar power to use at night and By storing excess energy, you can optimize the performance of your solar panels, increasing their overall efficiency and helping to lower your energy costs. 100% self-sufficient for most of the year.

5. Load Shifting

Energy storage units can be used to shift energy consumption to off-peak hours when energy prices are lower, reducing energy costs and increasing energy efficiency. Furthermore, it can ensure that power outages or natural disasters do not disrupt the energy supply. Ensuring improved resilience.

6. Increased Property Value

Installing an energy storage unit can increase the value of your property and make it more appealing to potential buyers.

Any Questions?

How does battery storage work with a solar panel system?

Battery storage works with a solar panel system by storing excess energy generated by the solar panels. This stored energy can then be used during times when the sun is not shining or when energy demand is higher. The battery storage system and solar panel system can be easily integrated, allowing you to optimise your energy efficiency and reduce your dependence on the grid.

Why is battery storage important?

Battery storage is important because it helps to increase the overall efficiency of renewable energy systems. By storing excess energy, you can reduce your dependence on the grid and increase your energy independence. Battery storage also helps to reduce energy costs by allowing you to use stored energy during times of peak demand when energy prices are higher.

How long does power from a Tesla Powerwall last?

This is a little complex to answer as it is dependent on where you live, your lifestyle, the size of your solar system and how much energy you use. Solar batteries make it possible for many households to run on solar power for 24 hours a day.

Make sure you talk to us so we can help you assess the right sized solar system for your current and future needs in order to meet your average daily usage as well as to make sure that the Tesla Powerwall not only lasts but allows you to maximise the benefits you’re getting.

Some customers with particularly high daily usage overnight (particularly on bigger properties) invest in multiple Powerwalls to better meet their energy needs. Powerwalls can be stacked (mounted one in front of the other with a Telsa Stacking Kit) or installed side-by-side.

How much power can a Tesla Powerwall hold?

The battery is sized to hold a capacity of 13.5 kWh. This means a typical family home will be able to run all evening on stored solar power from the Tesla Powerwall.

How much power can the Enphase IQ battery hold?

The third-gen IQ Battery 5P is the most powerful battery from Enphase yet. As an example, with two 5P batteries, you get 15.36kW of peak power and 7.68kW of continuous power.

How long is the Enphase IQ battery product warranty?

With an industry-leading 15-year limited warranty, you can feel confident knowing you’ll be saving money and contributing to a clean energy future for many years to come. Plus, an IP55 outdoor rating means you can trust the IQ Battery 5P to deliver power even in extreme weather.

What's the size of the Enphase IQ battery?

The IQ Battery 5P is modular by design, so you can start small, go big, or add more batteries as your energy needs grow over time.

Is the Enphase IQ battery loud?

Many batteries in the market rely on mechanical cooling, often resulting in noise. The Enphase IQ Battery 5P, however, stands out thanks to passive cooling and the absence of moving parts. This ensures enhanced reliability and quiet operation.

How long is the Tesla Powerwall product warranty?

The Tesla Powerwall product warranty is 10 years, with 70% minimum retained capacity, giving Aussie households the peace of mind that should anything go wrong, they will be covered.
