Frequently Asked Questions

How do I know what system is right for me?

Have a look at you electricity usage, there will be a summary each quarter of how much power you used. Think about if you were conservative or generous in how you used power. Then contact us, and we can work out which system is best suited to your requirements.

What is a kilowatt (kW)

So kW means kilowatt, which is 1000 Watts. It is a measure of power.

What is a kilowatt-hour?

A kWh is a measure of energy (not power). A kilowatt-hour is a measure of 1,000 watts during one hour. The abbreviation for kilowatt-hour is kWh. So 1,000 watts during one hour is 1 kWh. The power company measures energy in kWh in order to calculate your monthly bill. 5kWh is basic for a small home. 5 kWh battery bank is scalable for 10kWh, 15kWh, 20kwh or even more.

How do you calculate the number of kWh from watts?

If you want to know how many kWh an appliance uses, and already know how many watts it uses, the calculation is pretty straightforward.
First, you need to convert the number of watts into kW. To do that, you divide the number of watts by 1,000. So 100 W is 0.1 kW, 60 W is 0.06 kW, and 1500 W is 1.5 kW.
To get the number of kWh, you just multiply the number of kW by the number of hours the appliance is used for.

A simple example – A lightbulb that displays 100 Watt on its fixture will consume 1kW in 10 hours.
Another example, a device rated at 1500 W that’s on for 2.5 hours:
1500 ÷ 1000 = 1.5. That’s 1.5 kW.
1.5 x 2.5 = 3.75. So, a 1500 W appliance that’s on for 2.5 hours uses 3.75 kWh.

How do I calculate kW to kWh?

Calculating kWh from kW is even easier, as you already know the number of kW for the appliance. All you need to do is multiply the kW number by the time in hours. The 3 kW heater, if used for 3.5 hours, would use (3 x 3.5) 10.5 kWh of electricity.

How Many kWh Do You Need for your house?

An average Australian house consumes (approximately) electricity adding up to be 19 kW per day. How much electricity does an Australian Home use? This does depend on the size of your home and what appliances you have such as heaters and air conditions, TVs etc.

Breakdown of average residence’s energy is being consumed:

> 40% on heating and cooling

> 23% on water heating (electrical water heaters)
> 14% on miscellaneous appliances like dishwashers, washing machines, TVs and other entertainment appliances
> 8% on refrigerators and freezers
> 7% on lighting (light bulbs)
> 5% on cooking

Most modern homes today are equipped with the latest electrical appliances for daily chores and entertainment. Even while they may be the latest energy efficient appliances, they will still add to more power consumption. Also remember, that your own household electricity usage will vary from others depending upon where you live and how you use your appliances and devices in your own home. How do kW and kWh relate to batteries?

How do kW and kWh relate to batteries?

When buying batteries, you need to think about both the power of the battery and the energy storage capacity of the battery you are looking at.

The battery’s energy storage capacity is measured in kWh—for example, the Powervault ’ stores 8 kWh of energy.

Its power is 6 kW charging (Max discharge 9000w), so it can charge or discharge at that rate.

The more energy (kWh) a battery has, the more you can store and the longer it will last, the more power it has the faster you can get that energy in or out of the battery,

In other words, the more power it has, the more appliances you can power with it and the more energy it has, the longer you can power those appliances.

For normal household use, you want enough energy to get you through the night and at least 5 kW of power for speedy charging.
