Orion XS 1400 DVCC and remote on/off

Q&A and troubleshooting
, ,
1

I have a truck with a auxiliary switch. The switch provides +12V from the battery only when the engine is running. I want to connect this to my ORION XS, so I can remotely turn charging on/off. The ORION XS will be charging a secondary LiFePO4. I also have Victron MPPT charge controllers hooked up, and all of them connected to a venus os device through VE direct cables.

Can I control the charge current through DVCC and also use the remote enable/disable port at the same time?

If I’m getting 30 amps of solar then I only want to charge with 20 AMPS of alternator power.

DVCC will set a global limit. So being able to apportion it like that is not controllable normally.

There is possibly something that can be done with a node red flow, but i haven’t tried it.

DVCC controls the output current/voltage regardless of why the charger is running.

The remote on/off is only a force-disable, it is not a force-enable. In order for the Orion to start charging, both the input and output figures need to allow it as well as the remote on/off. For example engine shutdown detection and lockout voltages need to be properly set on the input, and charge voltages/DVCC need to allow charging on the output. You can override the engine shutdown detection, but still not fully force-enable charging.

Then set the charge current limit to 50A in DVCC. However take note that the system also needs some Shunt in it, either from a BMV, SmartShunt or SmartLithium NG with builtin shunt.

Why not hook the power feed from the truck to the Orion to a contactor/solenoid controlled by the aux switch?

5

I do have a smart shunt in my system.

I just want to be able to force disable the ORION XS from charging automatically If I don’t need to charge the battery immediately, and can instead rely on the solar to fully charge the battery. My question is whether force disabling charging with the High or low pin on the orion xs will be disabled if I am using DVCC.

I am following this diagram .

It seems like I can remove the jumper between L,H and hook up my aux switch to H. This will send H, +12V and enable charging correct?

In this diagram they show the jumper connected but I think thats a mistake.

Update: In the manual it says: “Applying >8V to the L-pin overrides the engine shutdown detection”

I’m trying to figure out what the manual is saying. ITs a bit confusing.

Seems like I need to disable engine shutdown detection in the settings and bridge the L And H Pins. When ignition is running it will provide +12V to L and H pins and enable charging I believe.

This example is for both remote on/off and engine shutdown detection override.

You want one of these

Probably b) H-Pin Wiring

If the H-Pin receives 12V then charging is possible, it will commence when engine shutdown detection, voltage lockout as well as DVCC are all “good” as well.

If the H-pin is free floating or pulled to ground then charging is disabled, doesnt matter if any of the other factors is “good”.
