    SMA Battery Storage


    Battery storage systems provide the capability to store electrical energy from solar panels in a chemical form, for use at a later time. The stored energy is used when the sunshine is not available, for example during the evening. Battery storage systems may also be configured to provide backup electricity when the main electricity grid is unavailable. Our battery solutions can be retro fit to most existing solar power systems with the smart AC coupling technology.

    Battery storage systems help make the most of solar:
    Fronius Hybrid Solar for Battery Storage


    Batteries are great for enhancing solar power systems. Instead of selling unused electricity to the grid for a fraction of the retail cost of power, you can store this energy on your property for later use.

    The stored energy is used when the sunshine is not available, for example during the evening.

    Reduce your net costs by directly offsetting evening electricity use, instead of just subsidising part of the cost through grid feed-in tariffs.

    Batteries can be installed at the same time as a solar power system, or retro fitted to existing systems.

      Take your property off-grid with a battery storage system:
      SMA Sunny Island for Off-Grid Battery Storage


      An off-grid solar system, also referred to as Remote Area Power System (RAPS) or stand-alone power system (SPS) is a great way to power your property where electricity is not available, unreliable or expensive to get. Also in Perth metro areas, many clients wish to be independent from the grid and install off-grid system. Solar panels produce electricity during the daytime, and charge the batteries. At night, the power is supplied from the batteries. An optional diesel or petrol generator can help to keep the battery size smaller. A solar battery system can also provide reliable power during bush fire emergency situations where properties are disconnected from the grid.

      The addition of the right battery component to any off-grid system solves these problems by storing energy for later use. For instance:

      • A battery allows for the electricity produced by solar panels to be used in the evening or when clouds move across your property.
      • An optional diesel or petrol generator can supply backup power if needed. The SMA Sunny Island system can automatically start and stop the generator should it be required.
      • A battery assists you to start demanding appliances, such as pumps and vacuums, that would normally exceed the electrical rating of your generator.
      • For grid connected customers, a battery system can provide power even if the grid goes down.

        Battery storage systems for peak-load shifting:
        Battery Peak Shaving


        Load shifting is exactly what is sounds like: shifting your electrical load (the electricity you draw from the grid) to a different time of day. Many buildings, such as offices or shops, are only operated for part of the day and use most of their electricity during this peak time.
        With a battery storage system you could draw electricity from the grid at off-peak times, such as the evening, for use during the peak operating hours. Synergy and other electricity retailers reward this behaviour by selling electricity at a cheaper rate during off-peak times of the day.
        A battery storage system allows you to buy electricity when it is cheap and store it for use during peak times, when the cost of electricity is much higher. From Synergy’s perspective, your property has shifted from a peak load to an off-peak load. This is because you are drawing power from the grid at an off-peak time of the day. Using a battery storage system in to avoid peak charges lets you save money on your power bill — without needing to change the actual time of day your office, shop, or home appliances run. This arrangement is perfect for buildings with set opening hours that cannot be easily modified.
