There are lots of supposed "3000W" or "5000W" inverters that are hard pushed to provide 1000W.
But assuming the
inverter genuinely can provide the quoted wattage that is not the end of the story. What Batteries are driving the
Inverter? what cables are connected between the Batteries and the
Inverter?
I was trying to think of an analogy to explain this and the best I can think of is this ....
Think of your setup as a car -
The
Inverter is the Engine, providing the power. The more power you have the faster you can go.
The
Battery Bank is the Fuel pump. The bigger the fuel pump is the more fuel can be sent to the Engine
The Cable is the fuel pipe. The larger the fuel pipe the more fuel it allows to be delivered to the Engine.
If you have a fuel pump designed for a 1000cc engine and you fit a 3500cc engine, it will not be able to run at full power as it is starved of fuel.
If you upgrade the fuel pump but don't change the fuel pipe, that bigger pump still can't deliver the required fuel as it is restricted by the pipe
If you upgrade the pipe but don't change the pump, it will not allow any more fuel to be delivered as the limit is the pump.
I am just saying the above and may be pointing out the obvious, but it is incredible how many folk buy these massive inverters but don't seem to realise that the energy to drive them has to come from somewhere!
