Solar Batteries Adelaide

With the rising costs of energy charges, many Adelaide people are turning to Solar Batteries for storage of power and supply of power as needed. This allows them to reduce power bills and gain independence from the energy providers.

Adelaide Solarsafe’s StorEdgeTM energy storage system (Solar Batteries) is perfect for this purpose. When combined with SolarEdge and cloud-based monitoring you will have the latest in elite home energy management and storage systems.


SolarEdge is an optimisation system that allows each panel to operate independently from each other. Most solar installations string each panel together. If one panel is shaded by a tree, all the panels in your solar installation are impacted and your Solar PV (photovoltaics – electricity produced from solar energy) is reduced. With SolarEdge, only the panel that is shaded is affected. Every other panel continues to produce the maximum solar PV that it can.

This means more energy saved!

StorEdge is a storage system for your solar PV that works with a battery and the energy provider. The solar power system stores PV power over what you are using, as you receive it and exports it to the grid when the battery is charged. This gives you direct PV power first, stored power second and the grid power last. It works on a cycle and is easier to explain by giving you an example of that cycle.

Just prior to sunrise, you are using grid power. As the sun rises, your panels become active and start to take over the power production of the household. As the PV coming in exceeds the usage, the battery starts to charge. Once the battery is charged, the excess is exported to the grid. If at any time during the day, the usage exceeds the PV coming in, the battery takes over the supply of power to the household. When the usage drops back down or the PV coming in rises again, the supply reverts and the battery returns to charging. When the battery is full, any extra PV over what you are using is sent to the grid. Once the sun goes down and PV direct usage stops, the battery takes over supplying power to the household. When the battery is drained, power supply is then handled by the grid (the energy provider).

Back-Up Power Also!

It is also possible for StorEdge to be a back-up power supplier for the house if there is an interruption to the grid supply on pre-selected loads. This uses a combination of PV and battery, depending on time of day and PV coming in. During night-time, the battery takes over powering the important loads.

SolarEdge Monitoring

The monitoring platform allows you to see real-time data in relation to the households PV production, consumption, storage and the flow between the PV array, battery, grid and house loads.

Benefits of the StorEdge System

  • The major benefit you can see is the increase in energy harvesting due to the optimisers. This means power is stored in the battery quicker and more is exported to the grid.
  • A single PV and Battery Inverter is used providing a higher efficiency and this results in a simple design and easier installation.
  • Full visibility and easy maintenance due to the monitoring software. This can result in smarter energy consumption and will reduce electricity bills.

The Top 7 Things to Know When Buying a Solar System

Congratulations! You’ve made the first step in purchasing a Solar System, the decision to research Solar Systems. You have a lot of choices to make in regards to what type, who from, with or without batteries, which rebate offer, what size system and where it is going on the roof. Sounds a lot, I know, but here at Adelaide Solar Safe we promise to provide you with accurate and honest information to assist you with all these questions and any others that you have. To help start you off, here is a list of what we believe are the top 7 things you need to know or look out for.

1 – Stop waiting for the prices of batteries to drop!

The current payoff for some battery systems is around 7 years but some are up to 15 years. With warranties up to 10 years this doesn’t seem like a good idea.
However, all systems can have a battery added later, either through a method called A/C coupling or a Hybrid Inverter. With this knowledge and the rising costs of electricity, it makes no sense to wait for battery prices to drop. Get a well-designed solar system now and through your reduced costs of electricity, you will be able to save for and add a battery sooner.
Be aware though that an A/C coupled system will not provide back-up power as the inverter will still shut down when the grid fails. We recommend the installation of a Hybrid Inverter that will stay “on-line” when the grid goes down. These type of inverters will then direct either Solar PV power or stored battery power to operate essential circuits within your home. To clarify, there are two terms used here – Battery Ready and Battery Back-Up.
Battery Ready – Is a general term relating to the addition of batteries at a later stage. This does not mean that the batteries will provide power to the home when the grid fails.
Battery Back-Up – This term relates to a Hybrid Inverter that remains on line when the grid fails and it automatically chooses to supply power either from the Solar Panels or Battery Storage to your home when the grid fails. This type of inverter has a substantial cost addition to most standard “grid-connected” inverters currently being installed in Australia.
To give you a price comparison, at Adelaide SolarSafe in 2010, we were installing 5kw premium Solar Installations, for around $15,000 including GST. In 2017 Adelaide Solar safe can supply and install 5kw Solar and include 6.5kWh LG Chem RESU LV Lithium Battery storage with Hybrid inverter for around the cost.

2 – Get Multiple Quotes

To make sure that you get the best price for the quality you are after it is absolutely necessary to get multiple quotes. Not only will you avoid the unscrupulous installer who is charging three times more than they should but you can gain an understanding of which solar system is right for you and your budget.

3 – Ask Questions to Determine if your Solar Installer is the Read Deal

Know your stuff before the installer comes out to give you a quote. If they are the real deal, they will be happy to answer and give you the answers you already know. If they are not a proper installer or someone trying to rip you off they will make a mistake or realise they can’t fool you. In any case, verify the information with an independent source if you can. If another salesman can’t corroborate the information, try Googling it.

4 – Overhanging Trees or your Roof Isn’t on the Best Angle should not be a Deterrent

The latest panels are so efficient that any loss of direct sunlight is hardly noticeable. Current estimates put it at about a 10-15% loss if your panels are not facing north. Depending on the time of day you use your electricity, it may be a better option if your panels do face east (for morning use) or west (for afternoon use).
Overhanging trees can cause shadow but as the sun progresses through the sky that shadow will move. Depending on the shadow cast by the tree you may only be in the shadow for an hour. In an overall sense, your loss for that hour would be hardly noticeable at all.

5 – Know What Size System is Best for Your Needs

Most installers/salespeople will sit down and discuss with you what your electricity habits are or ask to see previous bills to determine what sort of usage you have before they provide a quote. They should then ask what outcome you are hoping for and what you are willing to spend to get that outcome.

6 – Become Aware Of How The ‘Rebate’ Works and/or How To Calculate The Paybacks From Feed-In Tariffs

Let’s define these terms first.
Rebate – a Federal Government financial incentive, upfront reduction in your cost to purchase a Solar System.
Feed-In Tariff – a State Government financial incentive, any excess solar energy (not used in your home) that is exported into the grid earns a payback by your electricity provider.
How does the Rebate work?
It’s not actually called a rebate but the STC program. The Small-scale Technology Certificate price varies depending on the demand of Solar Systems at that time. The higher the demand the lower the ‘rebate’. In August 2017 the STC was around $31 which equates to a rebate roughly equal to $600 per kW installed. The other thing to be aware of here is that the STC program is now being reduced every year, from Jan 2017, until it ends in 2032. With that in mind, you will get a better rebate now, (depending on the current STC prices) than if you wait. By the way, the STC price will be locked into any quotes you get.
You don’t need to worry about paperwork for this as the installers are the ones who claim the rebate on your behalf.
The only criteria for claiming it are:

  1. Your system is less than 100kW in size.
  2. You get it installed and designed by a Clean Energy Council accredited professional.
  3. You use panels and inverters that are approved for use in Australia by the Clean Energy Council.

How does the Feed-In Tariff work?

Let’s explain this in an example. Over a 24 hour period, you might use 30% of the solar energy that is stored during the daylight hours. The other 70% is exported back into the grid. Your electricity provider will tell you what your feed-in tariff is (usually between 6-12c per kWh). If we say it was a 10 hour day of sunlight, then 70% would be 7 hours of energy storage which has been saved. If your system is a 5kW of power system then you can produce up to 5kWh of energy per hour on a really sunny day. So, 7 hours at 5kW would equal 35kWh for the day. If your feed-in tariff is 10c then you earned $3.50 for that day. For a 30 day month, if that happened every day, it would be $105 you earned. That’s roughly $315 per quarter. Your electricity provider will take this off whatever energy you had to buy from the grid, for example, you buy $500 worth, receive a $300 feed-in tariff reduction, your end cost to pay to the provider is $200.

This means the bigger the solar system you get the more energy you can put back into the grid but it doesn’t mean you won’t get a bill ever again. The feed-in tariffs today are much smaller than 4 or 5 years ago. You will get reductions in your bills but probably won’t get a cheque instead.

At the moment the standard Feed-In Tariff (Aug 2017) is around 6c/kWh for exported energy. Some Energy retailers are offering around 16c/kWh. We would advise consumers to “tread carefully” when looking at these types of offers. The main kicker is how much the Energy Retailer is charging for “Imported Power” and what contract period are they attempting to lock you into. We strongly recommend seeking advice from those of us who are at the coalface. By that, I mean when Adelaide SolarSafe is providing a solar quotation, we need to complete an energy assessment. This allows us to calculate the proposed return on your investment. We see many of our client’s power bills and there is a massive variation between Energy Retailers current rates, pardon the pun.

As a general rule, with the new introduced energy charges (as from July 1st 2017) we see a range of 32c/kWh – 40c/kWh for imported energy. AFTER PAY ON TIME DISCOUNTS! The best I have seen recently (

AFTER PAY ON TIME DISCOUNTS! The best I have seen recently (post-July 1st this year) was Simply Energy, with a combined discount given to RAA members only.
Please note – We are not affiliated with any Energy retailer, it’s what we have seen in the client’s home.

7 – The Law: Australian Consumer Law and the Protections you are Entitled Too

While there are several basic protections the main ones that you will be concerned with are the warranties and what the installer/salesperson tells you.
Warranties – There should be four warranties with your solar system: the Performance Warranty, the Inverter’s Warranty, The Solar Panels Warranty and the Workmanship Warranty.
The Performance Warranty is on the performance of the whole Solar System, not the individual parts. Parts have their own warranties, the Inverter and the Solar Panels, both of which you should look for 10 years of coverage. The Workmanship warranty is obviously on the workmanship carried out by the Installer. Look for a 5 year warranty for Workmanship.

Check that the parts are covered by an Australian Entity. It has occurred that some Chinese made panels needed to be sent back to China at the customer’s expense to get them tested.
Be aware also that good quality systems will only need to be service once every 5 years and cleaned once per year. If an installer tries to tell you that it needs to happen every two years it’s either a poorer quality unit or the installer is not being honest. If they tell you to pay a maintenance fee to keep the panels in warranty, ask them to leave as that is a complete falsehood.


Hopefully, this knowledge has prepared you for the next stage, getting quotes and asking all the right questions. If you enter into your quest for a Solar System with the knowledge we have armed you with, you are likely to succeed and come out on top.

Why you should use Solar Batteries

Solar batteries – A new use. Old technology

Solar Batteries are a relatively new application for an old technology. Batteries were the earliest method of generating electricity, and the earliest battery was constructed in 1836 by John Daniell who discovered he could generate electricity from a copper pot filled with a copper sulfate solution.

Over the years battery technology has advanced in leaps and bounds to the state of the art Lithium Ion batteries used in most portable electronics today. Solar batteries typically use lithium batteries as well – the Tesla power wall and Enphase Solar Battery systems use lithium ion battery technology.

Solar Batteries – Power when there’s no sunlight

The need for solar storage evolves from a simple fact – solar power can only be generated using daylight – when the sun is out. Further, the typical household consumes more power in the evening – when there is no sunlight and hence no opportunity to generate solar power – as illustrated by the enPhase diagram:

solar batteries strategy

The modern family are at work and school returning to the home late afternoon early evening. Power for lighting, cooking and entertainment starts to be consumed. even with a solar power system installed, the household doesn’t gain the full benefit of the free solar power, and so mains power will be consumed.

Solar batteries – shifting the solar power to peak usage hours

A Solar battery system literally  time-shifts the power from the peak solar power generation period 9am-3pm to the peak power consumption period 5pm-10pm. The end result is not only a more efficient and eco-friendly use of the solar power installation, but properly tuned, this arrangement will save the household money because of a significantly reduced mains power consumption.

Australian made solar battery solution is recyclable

solar batteryThe ZCell solar battery is more recyclable than competing solar storage systems.  The ZCell uses zinc bromide solar battery technology rather than lithium that is used in many competing products and most notably the popular Tesla Wall power solar battery solution.

“The active parts are plastic, aluminium and steel, the fluid electrolyte can be removed and cleaned and put in the next battery so the whole thing is very recyclable,” executive chairman Simon Hackett said.

About 8,000 tonnes of lithium-ion batteries are thrown away every year and in the next 20 years that is expected to jump to 150,000 tonnes, partly due to a rise in the use of big home solar batteries, according to the Australian Battery Recycling Initiative.

Some of the z-cells technical parameters include:

Some key characteristics of ZCell are:

  • 48 Volt DC nominal battery
  • Maximum 10kWh energy output per daily cycle
  • Full 10kWh cycle depth available
  • Warranted electrode stack lifetime 30,000 kWh energy throughput or ten years (whichever comes first)
  • Expected electrode stack throughput 40,000 kWh
  • No cycle depth limitations – battery performance and lifetime is not sensitive to cycle depth
  • Charge current 50A continuous (linear charge curve, no drop in charge rate up to 100% full)
  • Discharge current 75A continuous, 100A for 30 minutes, 125A for one minute
  • Operating electrolyte temperature range of 10-45 degrees Celsius. Operation at ambient temperatures outside of this range can often be maintained
    See this FAQ for more details.
  • On-board battery management, control and monitoring system. Monitors electrolyte fluid and outside ambient temperature, cell voltage, charge/discharge current, and includes two fluid leak detectors.
  • Battery can suspend operations automatically if safe limits are exceeded (to self-protect). Where appropriate,

Solar Batteries

The ACT is leading the solar batteries adoption race with an initiative to award grants of up to $600,000 to businesses who install battery storage across Canberra. The pilot will lead into a renewable auction, aiming to install battery storage in 5,000 homes and businesses over four years. To help achieve the ACT’s target of 90 per cent renewable energy by 2020.

Solar batteries metering

Environment Minister Simon Corbell said “Low-cost energy storage is the missing link in the transition to a 100 percent renewable energy grid. The ACT is determined to play its part in developing this emerging industry.” “We expect up to $25 million to be available to support about 26MW of battery storage to be rolled out in more than 5,000 Canberra homes and businesses over the next four years,” Mr Corbell said.

This will be the largest deployment of solar battery technology outside of Germany
