Frequently Asked Questions
What is a Battery Energy Storage System?
Also known as solar battery storage or solar energy storage, a battery energy storage system is used to store the energy collected from your solar panels. Rather than sending it back to the grid, the energy is stored in a battery. At times when you are not generating sufficient solar power, rather than pulling power from the grid, your home will use the energy stored in your solar battery system.
Why invest in solar panel battery storage?
With rebate and feed-in tariff rollbacks being introduced in NSW and SA, the value you will receive for feeding power back into the grid will diminish, yet you will still be paying for the power you take from the grid when your solar panels are not generating power. By storing your power you are able to use it later, thus remaining off the grid and saving money. This helps make the most of your solar investment.
Before you get solar, consider battery storage:
- Before your rebate and feed-in tariff expires you need to consider battery storage to maintain the financial savings from your solar.
- When buying a new solar system it is important to make sure a battery-ready hybrid inverter is included.
- Now that you have a solar system, which includes a hybrid inverter, you are ready for battery energy storage installation.
- Receive huge benefits with community energy buying. With the adoption of new technology installers are reluctant to install single units but see the benefit of installing multiple units.
- BESS offer these savings to support local installers through the early adoption phase of battery storage using Lithium technology.
- Having your own battery storage will give you full control of your power. Solar Strata Power, Community Lithium Storage, Strata Solar, Reposit Power or whatever other scheme is on the market will charge you for their service. This will bite into the savings you could achieve by being independent.

Deciding on a battery
There are plenty of things to consider when investing in solar battery storage. We’ve outlined a few key points below. To learn more visit our Batteries page.
There are two types of batteries available for solar storage; lead-acid batteries and lithium-ion batteries. In general lead-based batteries are cheaper to purchase, they have a significantly shorter lifespan than lithium-ion based batteries.
Your solar battery system should be a long-term investment. Look for a brand that offers longevity and peace of mind like the LG Chem RESU plus range, which has a 10 year warranty and 15 year lifespan.
Also consider where your battery needs to be installed. All LG Chem RESU batteries can be installed inside or outside your home, including the high voltage LG Chem RESU 7H and LG Chem RESU 10H, making installation options easy.
As our lives change, so do our power usage needs. When purchasing a solar storage system, don’t just think about how much power you need now; think about your power usage in the future.
Does your system have the flexibility to change over time?
Batteries such as The LG Chem RESU 3.3, RESU 6.5 and the RESU 10 can enable you to expand your system to 20kWh of storage with banking two RESU 10 units or with any combination (6.5+10)=16.5 kWh or (10+10)=20 kWh.

Is the answer to be blackout free to buy an LG Chem RESU battery or a generator?
You can buy a generator very cheaply. The Honda Inverter EU20i which will give you 2kWs of power for $2200.00 is an option, but will it really do the job you want it to do?
When you start your generator how do you control it if you need to run a light bulb or the freezer? The simple answer is you can't. For situations where power is needed to run essential services like the water pump, does this mean you need to pull the cord to start the generator each time you flush the loo or for your child to wash their hands? The answer is yes. The larger the generator the more power you can use for your home, but what are the running costs? Typically these generators have small petrol tanks, so four hours running time is all you can expect before refilling the tank. Over a blackout you could expect to fill your tank several times.
On the other hand, if you have existing solar with a battery ready inverter, adding a small battery like the LG Chem RESU 3.3 to your system would require an outlay of around $4000.00 and when a blackout does occur, you could have un interupted power to your home. The battery enables the solar to remain on, giving you access to the power the solar generates unlike what happens where the solar no longer works for you without battery storage in a blackout. There is limited disruption to the household with a battery included in your system.
With both examples, battery storage and using a petrol generator, running heavy power consuming appliances like airconditioning and electric ovens would be limited. But essential power consumption can be achieved to run lights and computers etc.
There are a variety of inverters that could be candidates for the new low voltage and high voltage battery storage products coming on the market. These include the SMA AC couple High Voltage, GoodweES-series, Fronius Symo Hybrid, Delta Solarcity Exclusive, Redback SH4600, Ingeteam Ingecon Sunstorage, Victron Energy, SolarEdge SE, HD Wave, Selectronic SP PRO and ABB Inverter SMA Sunny Boy Storage.
