A BATTERY STORAGE SYSTEM CAN:

Ø  Help reduce your reliance on electricity from the grid.

Ø  Maximise the energy from your solar panels by allowing you to capture the solar energy that would normally be sent to the grid and save it for your own usage later in the day.

Ø  Offset the increased cost of power used during peak times, such as during the evening.

Ø  Save money by storing energy from the grid overnight when prices are low to use during peak times when prices are high (depending on your power agreement).

Ø  Provide electricity to your home during power outages (depending on your system).

Ø  Reduce your exposure to future electricity price rises.

How Do Batteries Work ?

Battery storage uses a chemical process to store electrical energy, which can then be used at a later time. For example, a solar powered torch stores electrochemical energy during the daylight hours that can be used to provide light at night.

In practice, battery storage systems can operate in a number of different ways.

A battery storage system connects to a house in two main ways —— DC (direct current) coupled or AC (alternating current) coupled.

A DC - coupled battery storage system is integrated into your solar system. These systems generally have a single inverter that converts the DC electricity to AC to supply your house, or feed back into the grid.

An AC - coupled system is separate to your solar system. It connects directly to your house wiring via its own dedicated bi - directional battery inverter, using local AC electricity to charge the battery and then discharge it directly to your house.

Each system has its own benefits. It is best to discuss the different options with your system designer.

The Three Most Common Ways To Purchase A Battery Storage System

When purchasing a battery storage system it is important to discuss your needs with a system designer. They will help you choose the best way to set up your system. The most common ways to purchase a system are shown as follows.

What Different Types Of Batteries Are Available ?

OTHER TECHNOLOGY TYPES

Other technology types include nickel - cadmium, nickel - metal hydride and flow batteries, but these are less common.

How Much Do Batteries Cost ?

While the price of battery storage systems is falling rapidly, the cost to install a household system is still significant. The fully installed costs of a system are likely to be around $1000 – $2000 per kWh.

Some providers may offer leasing arrangements or payment plans, but make sure you check the details and ask for the total costs of any plan.

Once installed, the cost of running a battery storage system is minimal. It's important to have a maintenance plan in place to ensure your battery is running safely and efficiently, so speak to your retailer about any ongoing maintenance costs.
