There is power going into the 24 volt dc to dc isolated Orion Smart charger at 25.42v. 25.42 volts is going out of the charger, as well. However, there are no lights on, blue or green, and when I open Victron Connect on my iPhone it is not connecting to the charger. I have, twice, followed the instructions to get it going: removing the remote connector with the wire bridge and then installing the inputs (I assume with power going into the charger) and then open up Victron Connect. I get nothing after doing that. I have followed all the rules and steps in troubleshooting about what to do and what not to do. I turned my Phone off and on and even deleted the app and reinstalled it. Still nothing. Just not pairing. Any ideas what else I could try or any ideas about what might be causing it? Thanks so much.
No, it’s just not charging. The unit is powered without the remote bridge, that’s why the manual is written the way that it is. Removal of the remote bridge allows the unit to be programmed before it starts charging, to ensure that it doesn’t start charging (with possibly dangerously incorrect voltages) immediately upon connection.
I think this is just your battery voltage - it’s not coming “out” of the charger, it’s just vBatt measured at the terminals. Post a few photos of the setup, with the connections at the charger shown as well as the connections to each battery.
Here are photos of the set up. Order from the 48v motor battery bank is as follows: 48v to 24v converter (light on). Not a bluetooth unit. 24v to 24v converter/charger. Smart unit/bluetooth and no lights, blue or green. 24v to 12v converter (light on). Not a bluetooth unit.
25.42v at the fuse after the 24v to 24v converter charger outlet but, no lights are on and I cannot connect to (or detect) this unit thru the Victon app.
Any advice where to go from here appreciated. Thanks.
Ok. Will try it. Thanks. Have a question though, What will the 50w bulb show that you can’t get with multimeter?
I knew I was going to get myself in trouble saying “same” “25.42v”. That is the voltage in. The voltage out I can’t remember now and I didn’t write it down because it wasn’t much different. Was + or - .5v difference. Was only a little lie.
Thanks so much your help. I did the light test as you said. Wasn’t 50w. Was this 12v led light that apparently also works with 24v.
Here are results.
48v to 24v converter
The light does not go on at the 24v outlet of the 48v to 24v converter. However, the green light is on. Not a bluetooth device.
24v dc to dc charger
The light comes on at the “in” and “out” ports of the fuse block after the 24v charger outlet. This is a bluetooth device. The green and blue lights are off and I cannot detect this device through the app.
Ok. Did the 50w light bulb test and here are results.
The 24v output, and fuse, of the 48v to 24v converter lights up when the negative lead is connected to negative output screw on the unit. Does not light up when negative lead is connected to 24v negative busbar.
The 24v input, of the 24v DC to DC charger converter, lights up when negative lead is connected to charger negative screw. Does not light up when negative lead is connected to negative busbar.
Only the 24v output, and fuse, of the smart 24v DC to DC charger, lights up when negative lead is connected to negative bus.
Not sure why this happening. Hopefully you will have some idea. Feels like something is just not connected correctly but, I have no clue what. All the wiring seems to be connected correctly. Thanks again for all your help.
I don’t know why the light won’t work at the input side on the 24v charger. The charger green and blue lights are not lit.
The 48v to 24v converter output feeds the 24v power to the 24v charger. However, the light is not coming on when the negative lead is connected to the bus bar on the 48v to 24v converter and the positive lead is connected to the output of the converter. It does come on when the negative lead is connected to the output’s negative screw.
Attached are a couple photos of the converter / charger / converter units and a drawing of the set up. Please let me know if there is any additional information you need. Thanks.

Here is the sequence of fixtures for the + wire:48v battery bank
fuse
48v to 24v DC to DC converter
fuse
24v charger
fuse
24v battery bank
fuse
24v bus bar
fuse
24v to 12v converter
fuse
12v bus bar
48 volts comes in from the fuse of the 48v battery bank to the input of the 48v to 24v converter.
The output on the 48v to 24v converter is connected to a fuse which is connected to the input of the 24v charger.
The output on the 24v charger is connected to the 24v battery bank.
The 24v batterybank is connected to the 24v busbar.
24v busbar is connected to the input of the 24v to 12 v converter
Sequence for negative/- wires:
48v is connected to the input of the 48 to 24v converter.
The output of the 48 to 24v converter is connected to the input of the 24v charger.
The output of the 24v charger is connected to the negative bus bar.
The 24v negative busbar is connected to the negative pole of the 24v battery bank.
There is NO power (meaning the 50watt bulb doesn’t light up) at the output of the 48v to 24v converter and at the input of the 24v charger, which are connected to each other.
There IS power at the output of the 24v charger but not at the input, as mentioned above. I would say that the problem is NOT between the 24v charger and the 24v battery bank but IS between the 48v to 24v converter output and the 24v charger input.
For some reason there is no power coming out of the 48v to 24v converter which means no power going into the 24v charger. Maybe the 48v to 24v converter is bad, because there is no power coming out of it, but the green light is on on that unit. Can that happen even when there is no power coming out of it?
When I connect the light to the output positive and negative terminals of the 48v to 24v converter the light comes on. When I connect the negative lead to the busbar, instead of the output negative terminal, the light does NOT come on.
The negative wire from the 48v to 24v converter is connected to the negative input terminal on the 24v charger. The wire from the negative output of the 24v charger IS connected to the 24v busbar. There are no awol wires that I can find.
You don’t have it right yet. I get NO power (ie: light does not go on) at the 48v to 24v output terminal and at the 24v charger input terminal, which is coming from the 48v to 24v converter output. IF you cannot help me where do I get help from Victron? THanks for all your help so far. I appreciate it.
Ok. This is one of the downsides of this kind of troubleshooting with words, and multiple of devices, and connections both in and out. Can get confusing with multiple of emails. Thought I was being clear and I sent diagrams and photos, but guess not. I’ll call the local distributor. Thanks for trying.
