Modern inverters have caused a quiet revolution in the way that we live with independent power systems, by providing silent 240V AC electricity anywhere, any time from a 12V DC battery.
Inverters transform the DC electricity stored in your batteries into standard household 240V power. Thus, you can run 240V appliances from the DC battery system in your 4WD, boat, caravan or motorhome.
There are two main types of inverters available today.
Modified Sine Wave
Modified Sine Wave inverters are the cheaper of the two types. They can be safely used on resistive loads like a small heater or an electric drill without variable speed control. If this type is used on electric devices like, variable speed drill, laptop, TV, CPap, microwave, etc, damage can be caused to any of these items. We do not sell this type of inverter.
True Sine Wave
These inverters are the most sophisticated inverters available on the market today.
They are designed to produce ac power which is equal or better than your mains power at home. With correct sizing of the inverter any equipment you use at home can be run from a True Sine Wave inverter.
At Nimbus Engineering we point out to customers that safety is paramount with inverters that make 240V ac power. There is an inverter sold in Australia that is potentially very dangerous. If we see one of these in your setup we explain the safety issue. Our double insulated inverters do not have the above problem.
Special set up we can provide in caravans
When you plug your van into outside power all your 240v appliances work, example: toaster, microwave, battery charger, TV, Aircon GPO’s.
We can install a 2,500w or 3,500w inverter in your van in such a way that when you are free camping you can also turn on any of the 240V appliances mentioned above.
These inverters have an inbuilt change over switch which when integrated with your circuit provides ac power to all power points in the van when free camping.
You are given an Electrical Certificate of Compliance when we set this system up in your van.
Powering Sleep Apnea machines
When people have sleep apnea machines they need to be powered reliably.
If you have a 240V unit we can supply a small inverter, separate from the large one to run your other appliances.
Reason: Large inverters when turned on but doing nothing can self-consume up to 3.6A (as much as a 12V fridge). A smaller 300w inverter to run your sleep apnea machine will only self-consume 0.3A, so will not deplete your house battery.
If you have a 12V sleep apnea machine, it will be supplied with a wall cigarette lighter plug. This is not a reliable connection and as this machine is there to ensure you wake up in the morning, we fix this problem by removing the cigarette plug and replace with a German Din Plug and Socket.
Thus you can then be assured the unit will be powered the whole night through.
The small inverter is also good for charging small items like torches, laptops, etc, rather than using your large inverter for the small jobs.
