Integrating Battery to a AC/DC Controller for BLDC Solar Pump

[kaelz]

Hi , is there any way to integrate a battery back-up to a solar pump with AC/DC Controller and BLDC Motor ?

we already have this unit installed : 4DSC19-35-200-1500-A/D . But we are planning to add a battery back-up.

Thanks.

Welcome to the forum!

How many wires are leaving the controller and going to the pump? If it's like my solar pump there's 3 wires leaving and it's 3 phase AC going to pump from the controller.

How are you powering the controller now? With AC or Solar Direct?

3 wires are leaving from the controller going to the brushless dc submersible pump.

it is like an on-grid solar pump , solar panel and ac is connected to the controller.

Now we need a battery because it is used in the farm and need power even at night. And sometimes there is power outages.

is there anyway safe way to convert it to hybrid on-grid solar pump ?
