Solar Pump, Set up questions

Solar Pump, Set up ??

Do you need to pump at night ? (batteries required) or just daytime into elevated storage tank.

No, do not want to. Want to use panels to primarily power pump, as well as power other 12 V DC unit.

Know a lot about pumps and another 12 volt DC device, but nothing about DC power and Solar set ups.

Need your help;

Have;
-DC pump, in either 12, 24 or 36 Volt DC, 300 Watts
-DC Device 12 Volt DC, 11 amps

Thinking about using 400 Watt Panels. Don't want Batteries unless I have to.

Can I get a charge control device that produces 36 Volts DC AND 12 Volt DC?

What do I need to make this work most efficiently: Pump Controller? MTTP?

Help.
