What is a 12 volt inverter?
An inverter is a device that turns the power from a 12 volt DC battery, like the one in your car or truck, into the 120 volt AC power that runs all of the electronics in your house. You can use one of these devices to power all sorts of devices in your car, but it's important to figure out how big of an inverter you need first.
How to size an inverter?
If you want to know how to size an inverter, the answer is simple. All you have to do is find out how much power your devices need. Then, do some simple math to determine how much more power you need to compensate for inverter losses and headroom.
How much power does an inverter use?
Most inverters have an efficiency of between 60% and 80%. This efficiency can also be referred to as the power factor of an inverter. For our calculations, we would use a power factor of 0.8. Hence, Power supplied (or VA rating of the inverter) = Power consumed by equipment in watts / Power factor
What are the different solar inverter sizes?
Solar generators range in size from small generators for short camping trips to large off-grid power systems for a boat or house. Consequently, inverter sizes vary greatly. During our research, we discovered that most inverters range in size from 300 watts up to over 3000 watts. In this article, we guide you through the different inverter sizes.
How do I choose the right inverter size for my battery?
To find the right inverter size for your battery, first calculate your total electricity needs. Add a 20% margin to this total for future upgrades. Select an inverter that meets or exceeds this capacity. Ensure it can handle the power requirements of your appliances without risk of overloading. Consider the surge wattage.
How do you use a power inverter?
To use a power inverter, it needs to be connected to a 12 Volt battery, preferably a deep-cycle battery. In instances where more power is needed, multiple batteries can be wired in parallel to provide the necessary energy. It’s important to note that as the power is drawn out by the inverter, the battery will need to be recharged.
