Hi @lucylite

Your Easy has great AC 'distribution', but there's nothing in there for DC. I suppose it's possible to add stuff behind the front cover, but challenging. The onboard 'trickle charge' is low powered and best avoided for driving devices.

Just connect your pump to wherever the 24V cables from the Easy terminate. That may be a dc bus, or even the batteries. You may need an isolator, fuse, even a relay to the pump, but best treat it as battery supplied.
