How to work out what size inverter to buy.

The first thing you need to do is work out the load, that is, the total wattage you are going to need at one time. So how do you do this? Look at all your appliances and work out how many of them you will be using at the same time on a daily basis. For example, you may have a fridge that is plugged in all the time but at times you may plug in a kettle and have all the lights on. All at the same time. This would be your peak power usage and as such you simply add up each appliance individual wattage.

So the way it works is if you have all these appliances on at the same time, your Redarc Inverter needs to be able to handle these peak demand points, or else the safety protection built into the inverter will shut down.

To take this example further, your kettle may have a wattage of 1200 watts, your fridge may be drawing 100 whats and your lights another 200 watts. In this case the total load is 1500 watts. So it may be wise to choose a 2000 watt inverter so you have a bit of spare capacity. Remember, you dont always have to use these appliances at the same time, so if you get that overload warning sound you can always unplug one of the appliances while you finish your task with the others.

What are my Battery Requirements?

Next you need to work out if your battery bank is up to the task and a rule of thumb states that for every 200Ah of battery, say lithium deep cycle, you can power and inverter * 10 watt inverter, or 2000 watt inverter. Always ask your qualified auto technician to confirm your calculations but this simple calculation will give you some idea of your requirements.
Here at Monteltham Auto Electric we recommend the Redarc range of inverters which includes
350W, 700W, 1000W, 1500W, 2000W, 3000W modles. You can check out the Redarc range here: https://www.redarc.com.au/pure-sine-wave-inverters page which also provides a calculator based on how much you can afford.

Redarc Inverters are pure Sine Wave Inverters which provide you with exactly the same 240 volts you have at home. The fact that they are Pure Sine Wave Inverters means that the inverter will output a unique sine wave and so the output will be smoother and more reliable.

All the Redarc Inverters have a remote control which is a handy feature for controlling your Inverter, see this link: Inverter Remote Control

2000 watt Redarc Inverter 12V

With the REDARC’s 2000W Pure Sine Wave inverter you can plug in any 240 appliance and come in both 12v and 24v modles and they make sure that the appliances run smoothly and in an efficient manner, they produces very little heat or noise. They are also much thinner than the earlier models and also weigh less.
Overload Features
The 2000W inverter has various attributes which protect the inverter from overloading issues, electrical short circuitry and overheating. There is also a fan which kicks in at a certain load, ensuring the inverter stays cool and fuctional.
In other words with the REDARC 2000W inverter you can take all your home comforts with you on your travels knowing that you have the power without worrying about any harm to your appliances.

Remote Control

There is an optional Remote on/off switch (REMOTE-RS) mentioned before, (It all works with out the remote but it is handy) that allows the control of the inverter from a remote. One reason for the remote control is that the inverter can be fitted out of sight and you will still be able to control the inverter up to 8 meters away.
