Car remote power tool charger

Hi.
I have an ozito tool set for my business and want to charge on site at the car using my solar panel.
Would someone be able to assist my with a schematic or details how i can do this.
This is the charger

PXC 18V Multi Battery Fast Charger

Charge multiple Power X Change batteries at the same time with the Power X Change Multi Battery Fast Charger and get back to work faster.

and the solar panel specs are in the image for the solar panel.

You would need to set up your solar panel to charge something like a car battery. Then pass the battery through an inverter to plug into your battery charger circuit.
