DC pumps - how do they use them?

[TronxII]

Solar pumps 110V or the bigger one 185V DC, 17A, This is nice power and the pump will probably work much better than any other "solar toy pump".

But my question is, how do they use them?

I would struggle to find a nice way to connect them to ... what?

A 180V battery?  How to charge this?

An array of solar panels with 30 A output and no battery?  And then switch them on manually when the sun shines?  - imagine the spark at the DC switch

Maybe the Thai are more clever and have a simple solution, but for me I would struggle to make these work.

Apparently they sell them, so there might be a market.

Can anyone enlighten me please.

I have 4 solar well pumps, for irrigated and backup for my rainwater harvesting.

 

The irrigation pumps are switched on for a few days at a time in the dry season and only run when the sun is shining. 
 

I have a couple of tanks for well water. There is an electronic tank sensor that sends a signal to the pump controller to switch off when the tank is full. 
 

I don’t use batteries with any dc pumps as my house runs 100% on solar and home batteries.

Flyingtiger's video suggests these pumps need a separate controller.

Bandersnatch, are your pumps also  in this voltage range of  110 - 180V DC?

To what power do you connect these directly to the panels via some controller?

This Chinese girl will put your mind to rest.

The chinese girl has a power supply. But it seems that the controller box of the pump should be directly connected to the solar panels and handles switching on.

Thanks all for instructing me.
