Inverters

Neil,
The inverter will draw only what it needs to draw to run the load, plus a small overhead, so the capacity of the inverter will make little or no difference to the power used out of your 12V system.

In a well-designed inverter the overhead is small, but can be a significant drain on your 12V system if left switched on with no load for a long time.

Cheers

Look at the full specifications sheet and check the 12v load at idle (no output load). If the larger one is not significantly more then no issues.

The only disadvantage is the physical size of the inverter and the heavier cabling and fuse you have to use.

Be cautious re output of cheap inverters...... what they say and whet you get are sometime miles apart.

hi guys
i have installed a 2700 watt unit. this also doubles as a battery charger as required.
great unit and now the princess can make coffee, bread, and run her hairdryer.

Hi Neil,
If using a 2Kw inverter to power a mobile phone then yes the power draw will be high compared to what you require.
If you do the same from a 300W inverter then the difference would be say 20mins ish on a 100aH battery.

However if you do have the need for 2000~3000W i would suggest going for the 3000W , Reason you ask? Some appliances such as kettles are rated at 2000W when infact they sink the full 10amps @ 240V which is 2400W , This draw is held longer than the peak or surge of an Inverter can handle. Hence a 2kw inverter will fail sooner than later. Whilst a 3K you will have no issues.

For most camping travelling applications all you really need is a 600W PSW max.
600W will do CPAP machines, TV, DVD , tablets and laptops.

Rarely you see the 2000W unless using Pixie coffee machines.

3000W if you are adamant in powering heavy power tools or Kitchen cooking appliances.
(bare in mind you need the batteries to support this system)

All we take camping is the 600W Pure, and rarely go above 300W unless we take the fridge for the longer trips.
