Battery Storage System

A Home battery storage system is an interesting topic and remains high across the continent. An obvious benefit of solar panel system is to be able to store unused energy in a battery storage to use the electricity at night time or on low sunshine days. With an increasing cost of electricity and the tariffs associated with it, most people across Australia are determined to take as much advantage of solar photovoltaic (PV) power systems as they can. The smart home solar battery system can further help in save money on your energy bills. Thus, the installation of the solar battery storage reduces the burden on the grid or network, and facilitates the lowering of electricity prices in Australia. A solar battery power pack system is increasingly popular thanks to the high electricity prices, and is a real attraction to become as independent as possible from the grid. For some of us, it is not only an economic decision, but also a step to save environmental. This has introduced the concept of solar battery storage system across the solar power industry and Target Solar has welcome it by open arms. In addition, Target Solar is also an authorised provider for South Australia Home Battery Scheme.

How a Home Battery System works?

The idea of solar battery storage system isn’t novel. Many remotely operated Off-grid solar photovoltaic (PV) and wind energy power generation station has long used the concept of storing unused electricity for later use. Due to continual rise in electricity charges, it is predicated that in next 5 to 10 years in line, almost every homes will have solar home battery storage system.

There are few reasons you may want to add batteries in your solar panel system:

  • Use your generated solar energy at night time.
  • Reduce power consumption during peak periods.
  • Batteries can provide backup where there is a power outage.
  • Become more self-sufficient by reducing the effects of increasing electricity prices
  • Save money by charging your battery from your power grid at off-peak times.
Two ways to connect solar battery system to grid supply

Grid-connected solar + battery

These systems comprise of panels, an inverter, a battery and a connection to grid. The solar photovoltaic system converts energy received from the sun into electricity. The solar energy generated from panels is used in day-time, with an excess stored in battery system. During days of low-sunlight, high power usage or at night time, the power is drawn from the home battery system and then from the main grid as a last resort.

Off-grid solar + battery

Off-grid solution offers no connection to main electricity supply. The system either uses the power coming directly from solar panels or from the battery. In this system, the battery pack is the main energy source during night time or during days of low sunshine. Generally, off-grid systems are more expensive and complex, with more number of solar panels, high load handling inverter capability and large battery storage. Off-grid systems are affordable in remote places where no grid connection is available.

Types of Battery Storage System

Types of Battery Storage System

DC coupled battery storage system

It can only be connected with outputs generated by solar panels, therefore, only storing energy produced by solar panels.

AC coupled battery storage system

In this energy storage system, the yielded solar energy from the panels is stored in the batteries by employing a common solar inverter coupled to battery inverter or charger. Once connected to the AC side of the solar invertor, it allows the battery to store energy from both solar panels as well as the power grid.

Blackout scenario

A grid-connect home battery storage doesn`t work during a Blackout event. A blackout event is where you cannot use any energy generated from panels or stored in the battery. A grid-connected systems is protected from an event called islanding. During a blackout the engineer working on the grid is protected from the ``islands`` that can power the grid (from installed solar panels). Thus an anti-islanding protection is installed during your solar panel installation. Some inverters can provide power during blackouts, however making the whole system more expensive.
