Are you the owner of an RV, SUV, car, boat or other vehicle with enough free space like Honda BR-V, and want to be able to watch TV, cook, or power a laptop onboard? If yes, you’ll be needing a power inverter. But what are they, and what do they do? Read on to find out why you’ll need one to power your gadgets on the road. As a fun fact, power inverters are now also becoming more commonly used in air conditioning units for homes. Use of the technology is expanding.
What is a Power Inverter?
Basically, they are devices that turn your vehicle battery’s direct current (DC) into alternating current (AC) – the kind of electricity you have in outlets in your house, that are connected to the energy grid. Power inverters are not to be confused with catalytic converters, which control exhaust emissions.
Having a power converter means you can plug in your appliances and devices, and power them like you would through an electricity outlet in a house.
In your car, you can get USB adaptors for your cigarette lighter so that you can charge your phone or plug in your satnav. But for larger gadgets and electronics with proper plugs, you’ll need an inverter.
Working of a Power Inverter
Like we said, they convert currents to a type safe for use in vehicles. Your vehicle’s battery voltage provides a current that powers its internal workings – you’ll need to know which voltage your vehicle’s battery uses to choose the correct inverter.
The current supplied by a battery sticks on one circuit, in one direction – where the name ‘direct current’ comes from.
However, to power your gadgets, you’ll need alternating current, as those electronics need more power to function than the DC can provide. They’re made to function with the high-voltage AC current supplied in homes. If you are wondering ‘how to do my homework‘ to write a high-quality essay on electricity, consider EssayDoc.
Power inverters increase the DC voltage, change it to AC, then use it to power your devices. They amp up your battery’s voltage so you can play video games and use a kettle in your RV. Cool, huh?
These babies come in a variety of sizes – most commonly 1000, 3000 or 5000 watts.
It’s recommended that a 3000 watt inverter is the happy medium between inverter sizes and best choice to get. They’re not too small like the 1000, or too powerful and overcharged like the 5000. If you need a little extra boost, there are 3500 watt capacities available.
We spoke to a representative from Crusader Vans, who has a lot of knowledge on the topic at hand and they said, “The size you choose depends on the watts or amps of what you want to run (find the power consumption by referring to the specification plate on the appliance or tool). We recommend you buy a larger model than you think you’ll need (at least 20% more than your largest load).
Determine Continuous Load and Starting (Peak) Load: You need to determine how much power your tool or appliance (or combination of them that you would use at the same time) requires to start up (starting load), and also the continued running requirements (continuous load).” Follow this link to know more about them: https://www.crusader-vans.co.uk/
Modified or Pure Sine Wave Inverter?
Besides the sizing, there are two main types of inverter – the modified sine wave, and the pure sine wave.
So, what’s the difference, and which one will you need?
- Modified Sine Wave: These tend to be cheaper, and less powerful. However, they’re good for most everyday electronics you will want to use, just not very large ones.
- Pure Sine Wave: These are compatible with pretty much all electronics, gadgets, and appliances, and produce a powerful current most like the one supplied by the electric grid. These are the most common choice, because they’re more likely to be compatible with anything you need to plug in.
Other Features and Tips
- Power inverters are especially useful if you are setting up a solar power system – they convert energy from the sun into electricity you can use to power your gadgets within your vehicle. This is renewable energy that isn’t a drain on your best car battery.
- Power inverters aren’t just for vehicles – if you have a small cottage or outhouse, they’re very useful for setting up a small power source there.
- Many (but not all) power inverters come with USB outlets, useful for charging on the road without having to cart around adaptors and large plugs. For ease of use, get one compatible with USB.
- The best inverters have digital screens which show you how much energy has been consumed and information about battery voltage. It’s useful to know these things at a glance, so consider getting one that has a screen.
- Modern inverters, such as a solar inverter, have been made to be extra-quiet, so you won’t be woken up by a noisy machine while trying to simultaneously get some sleep and charge your phone in your RV.
