The following information will give you an idea of what size battery you will need.
Please contact our staff if you would like to discuss your energey needs in more detail.
Below is a table of the battery sizes we sell.
Each battery Model will give you the amount of kilowatt hours (kWhs) you can expect to get out of that model battery.
Our batteries have a usuable capacity of 80%.
To identify what size battery you will need to power your home, the best way is to look at how many kWhs you use on you electricity bill.
As a rough guide, a typical 4-person family uses between 16 - 20kWhs per day.
This is generally broken down to 30% during the day and 70% at night. Typically, the 70% is between 5.00pm and 8.00am and this is when a battery can provide you with power.
The next lines gives you an idea of how to use the table below to identify the size battery needed to cover the average 4-person family without solar on their roof.
Looking down the table you can see the both the L500ah @ 48V and the L1000 @ 24V both provide 19.2kWhs which can provide the 16-20kWhs per day a typical 4-person family uses.
If you have solar panels on your roof, you can reduce the battery size you need.
A typical solar installation is around 6.6kW and on average you will get about 20kwhs per day in Sydney, Australia over the year. This will be lower in Melbourne and Hobart but maybe higher in Brisbane and Darwin.
Remember solar panels only provide you with power during the day and 70% of your power consumption is done at night between 5.00pm and 8.00am.
This means that a battery needs to be able to provide the 70% of power used at night which is between 11.2 - 14kWhs for the average 4-person family.
The battery size options for 11.2 - 14kWhs in the table are: L1200 @ 12v (11.2kWh) L750 @ 24v (14.4kWh) or the L300 @ 48v (11.2kWh)
If you use gas for heating, cooking or hotwater, you can further reduce the battery size you need.

The voltage of a battery is important. All electrical appliances need amps to operate.
The more electrical appliances you need to turn on at once means the more amps you need.
The higher the voltage of a battery bank, the higher the amps it can provide.
Meaning a 48 volt battery will provide more amps than a 24 volt battery and a 24 volt battery will provide more amps than a 12 volt battery.
