What inverter should I use for 12V 9A

What voltage should a 12V inverter run on?

The input voltage of the inverter should match the battery voltage. (For example 12v battery for 12v inverter, 24v battery for 24v inverter and 48v battery for 48v inverter Summary What Will An Inverter Run & For How Long?

What size inverter do I Need?

What size Inverter?: What helps a lot with sizing and inverters is that they are measured in Watts, so all we need to do is look at the wattage of the 240V things we want to run, and size the inverter accordingly. Things like camera and phone chargers are typically less than 50 Watts, and most laptops are under 100 Watts.

What does a 12 volt inverter do?

Inverters are one of the most useful bits of power electronics around, but they are also one of the biggest consumers of 12Volt power, so we need to know what we’re doing when we invest in one of these beasts. In short the inverter’s job is to take the 12Volts DC we have in our battery, and convert it to a 240 Volt AC supply like we have at home.

How many Watts Does a 12 volt inverter use?

Things like camera and phone chargers are typically less than 50 Watts, and most laptops are under 100 Watts. So if we can restrict ourselves to those few things, a small efficient 150 Watt inverter will do just fine, and the current draw on the 12Volt side will be under 15 Amps – all quite manageable.

How to choose a power inverter?

Second, select an inverter. For this example, you will need a power inverter capable of handling 4500 watts. The continuous power requirement is actually 2250 but when sizing an inverter, you have to plan for the start up so the inverter can handle it. Third, you need to decide how long you want to run 2250 watts.

How much volt drop should a 12 volt inverter have?

Australian Standards say we should keep our volt-drop under 5% or 0.6 Volts on a 12Volt system, but with high-power inverters it’s best to keep this around 0.2 Volts so we don’t waste power in the cables. The volt-drop calculator is useful here, and allows us to choose a cable that will maximise the power into the inverter.
