Victron smart tr 12 /12/ 30A none isolation dc dc charger

1 - Victron Orion TR 30A DC 2DC power light doesn’t come on but charger functions normally. Why would this be? Bluetooth operation ok.

2 - Charge from Orion shows as negative on Cerbo DC tile and loads show as positive - can this be changed? (shunt is fitted and all negatives on correct side)

4 - Lynx Distributor with lights mod is showing orange/redish light but megafuse is intact? Why might this be?

5 - Fogstar Drift app current +/- matches cerbo display but battery % different?

Hi, please can you add some more details about your system, like a schematic to show how all the units are connected? This might help us understand the problems better.

Hi Mike

Thanks for getting back to me.
Please see attached.
Additionally I have a Frogstar driff 280ah lithium battery.

Cheers

Is it the non-smart version, without bluetooth? If so then its not a DC-DC charger, its a DC-DC powersupply. Theres no charge algorithm in the non-smart models, all you have is the potentiometer to set a fixed voltage

My inverter is 12v /1600w 70-16 230v
Mppt Solar charger 100 / 30a
Dc to Dc TR 12 / 12 / 30a none isolated
Solar panel is 300w
1000 lynks distributer

All Victron with the exception on the solar panel.

Hope this helps you a little more…

Cheers

As you say charger is operating normally, then possibly failed LED, not to worry too much.

Check the Battery is in fact connected to the battery side of the shunt. Reverse if needed.

PV charging should show same sense as the Orion.

As SOC is a derived measurement, it is not unusual for 2 different sources of SOC to be different. Check that you have the right parameters set up in the shunt, and then they should both synchronise to 100% at next full charge. After that, they should track reasonably. Shunt parameters can be tweaked to correct drift.

if by the ‘lights mod’ you are referring to this:

3.3. The RJ10 cable
The RJ10 cable supplies power to the Lynx Distributor from a Lynx Smart BMS or Lynx Shunt VE.Can and transfers data between
the Lynx Distributor and the Lynx Smart BMS.
The Lynx Distributor does not have an in-built power supply to supply its fuse detection circuit; it relies on this power to be
supplied from a Lynx Shunt VE.Can or a Lynx Smart BMS via the RJ10 cable. If the Lynx Distributor is used without a Lynx Shunt
VE.Can or a Lynx Smart BMS, it needs to be powered in an alternative way so that the fuse detection circuit is operational.
To power the RJ10 cable for standalone use, do the following:
• Connect pin 1 of the RJ10 connector to 5V (4.5V-5.5V).
• Connect pin 4 to GND.

with various 12V to 5V adapters being available, then the lights should operate as normal. is it the power LED or a fuse led that is showing the colour?

Powering up
When the Lynx Distributor is powered up by the Lynx Smart BMS, all LEDs will light up for one second, after which the address
briefly is shown via a fuse LED. Fuse 1 LED illuminates for Distributor A, Fuse 2 LED illuminates for Distributor B and so on. The
power LED is orange during power up and will turn green once power up is complete.

Hi Mike.

It’s a 12v Victron Orion TR Smart 12/12/30a 360w model.
