Heard some strange theories about battery storage and their usage in the city? So have we and we thought it was time to put your mind at rest with the facts rather than the fiction that some might have you believe.
1) Batteries aren’t Approved by Energex/Ergon!
There are a number of regulations to do with the installation of batteries in an urban residential setting. These relate to battery charging, the feed in Tariff and how they are housed. Once all these factors have been met then there is nothing to stop the installation of battery backup systems. The Solar Guys have installed a number of self-use and hybrid systems in SE Qld. All have been approved by Energex. We have also installed self-use and full off-grid systems all over Qld that have been approved by Ergon. Continue reading “Battery Myths Busted!” »
To get the most from your solar + battery system, make sure you take note of these useful tips on better battery usage and giving them the best chance for a long and thriving lifespan.
Limit the Depth of Discharge
The depth of discharge (DoD) is a preset amount that you can draw from your batteries until they need to be topped up again. By limiting the DoD to around 20-30% of the overall capacity of the batteries, you will get more cycles from the system and everything will last up to 3 times more than if the DoD is at 50-60%.
Although the size of the system upfront will need to be slightly higher and the usable power is limited each day, getting the DoD right is a vital part of the design process and you can start to modify your consumption behaviour and system usage to keep the DoD sustainable in the long term.

The explosion in solar + batteries is about to begin due to the changes to the feed in tariff. Economics would show that sending power to the grid for 8 cents and buying it back at 29 cents has only one outcome and that is to make the power retailers increase their profits. The game has changed.
What battery and solar panel option will give you the best result?
If you are considering going down this path it shows you are serious about installing a system that will perform and give an acceptable Return on Investment (ROI)
The days of a cookie cutter solar system selection has gone and the wheel has turned back to where it was when I started in solar back in the mid 1980s. That is a lot of work has to be done to design a system to achieve the best result (ROI).
Whacking on a standard 3, 4 or 5 kW system with a conventional grid connect inverter however cheap it is will prove to be less effective financially particularly when Tariff 12 (a time of use Tariff) becomes mandatory. This will happen sooner rather than later.
Luckily with the latest inverters that have power management facilities built in the design of the overall system has become much easier. No more in depth load analysis sheets listing the appliances used in the house, their wattage draw and hour many hours per day they will be used. This is all very tedious.
With the Nedap – Power Router Inverter it is possible to install a standard grid connect system with sizing based on the power bill. Run the system for a couple of months and then from bar graphs generated by the inverter check both the energy created and the power used in the home to size the battery bank for maximum ROI.
This methodology allows you to decide how much of your bill you wish to cover from the system. It is flexibility plus.
Solar Panel selection should be based on history, longevity, performance and the ability to generate power in low light conditions. My choice is either Kyocera (from Japan) that meets all the requirements or Winaico (from Taiwan) that meets most of the requirements.If you would like to know more about your battery options or to get more information about our ready to go inverter + Battery mySunBank kits (Which can be shipped across Australia) call 1300 750 055 or Click Here to send us a website enquiry and we will call you back.
Spring can often be the right time to give everything a clean and get it all shiny and new. Have you looked at your solar panels lately? They definitely don’t look like they just came out of the box.
That’s because in Brisbane we have been experiencing very dry weather mixed in with higher than normal temperatures during late winter. Without the winter rain to dampen things down a bit, it’s a lot dustier and a higher pollen count than normal. With winter back burning you also get bushfire smoke, haze and pollution in the air.

With mining development still continuing across the most isolated areas of the continent there is a strong need for solar hot water and solar power generation both for off-grid and as a partner to diesel grids.
With most mines having a minimum life expectancy of 15 to 20 years they lend themselves to solar and energy efficiency products.
The rapid developments in battery technologies has also increased the viability of solar power as a base-load option in mining camps. Then the diesel generator becomes a back up and not the only power generation option. Continue reading “Solar for Mining Installations & Camps” »
Coming into the storm season once again owners of cold rooms and large freezers full of valuable food items should be looking at how they can protect their investment when and if the grid goes down.
Country dwellers are often connected to SWER lines that regularly suffer from brown outs and black outs. The costs from these events can add up. With constant increases in demand from land developments the frequency of supply interruptions could also increase. Continue reading “Battery Back up for Rural Cold Stores & Freezers” »
