You just need a 12 volt powered volt timer relay to turn your new 12 volt DC pump on and off.

Here is the goof ball move I have seen people do with these things.
It is a time dry contact relay that runs a set of dry contacts.
Dry contacts are just a switch like your light switches in you house.
Wet contacts are just that they supply electricity.

You have to run one conductor through the switch first and then to the pump.
The other conductor goes straight to the pump.
This way when the relay closes it turns on the pump.
The power consumption of these timers is almost nothing.

People are hooking both pump wires to the timer expecting it to work.

Now to your inverter you should dump.
400 watts is the maximum amount of power it can consume.
I like to convert watts to amps because it makes things easy.

The maximum amount of power/currant your inverter can handle is 3.478 amps.

I am going to post this and be back.
