Connecting the 100-30 charge controller to a DC input of EcoFlow smart panel

Q&A and troubleshooting

This is for a camper van. I want to connect the battery to the charge controller and then connect the charge controller to the DC input of an EcoFlow AC/DC smart panel. But there are only two ports on the charge controller (battery and PV). From what I have read, this can be done but it would require two connections to the single port of the charge controller. I can not find anything that says this is okay? This is what I have found.

To connect a Victron 100/50 charge controller to an EcoFlow Smart AC/DC Distribution Panel, you’ll need to connect the Victron charge controller to the DC input of the EcoFlow panel, routing the wires through the designated DC input inlet. You can then connect your battery to the Victron controller and your solar panels to the controller’s PV terminals.

Again, this implies that there are two connections (smart panel and battery) taking place at one single port of the charge controller. This just doesn’t seem right to me.

Could I use a load switch or relay controlled by the charge controller’s VE.Direct port and then go from the relay to the DC input of the EcoFlow smart panel?

Daisy chaining low voltage connections like this is normal. It is possible to connect 2 cables to the B+ and B- terminals of the Victron charge controller. One set then goes to the battery via a fuse, the other to the DC distribution panel. If you have a charge controller with a “load output” then the dc distribution panel could connect to that, but would be current limited by the load output. The alternative would be to connect the distribution panel to the battery, and also connect the charge controller to the battery, with both connections being fused.

Thanks for the reply!

To confirm, this charge controller does NOT have the 3rd port, so I would have to double up on the battery terminal of the charge controller. I did hear back from Victron and they advised me NOT to connect two cables to the single battery port. Wouldn’t another option to be to go directly from the batteries to the DC Input of the EcoFlow Smart Panel? I am waiting to hear back from EcoFlow to see if this would require an inline fuse.
