I have just installed for a customer a Victron Orion Tr Smart 12/12 30A Charger to an RV.
We are charging 2 x 240ah LiFeP04 batteries in parallel.
There is also a Victron Smart Solar 100/30 Charge Controller connected in parallel.
The problem is that the Orion will not bulk charge at all, if I isolate the solar output and the Orion is left to do the bulk of the work.
I have checked the inputs from the vehicle and ensured the Orion will turn on to charge at the desired voltages. However it starts to charge - then displays a sudden drop in input voltage and stops charging. I have tried 2 different vehicles and monitored their voltage to confirm it is not actually dropping below the threshold.
If I turn on the Solar Charger it (the Solar Charger) immediately starts bulk charging (approx. 22A).
When the Solar Charger is doing the bulk charge the Orion will start working in absorption mode. But if left to do the bulk charge will keep cycling on and off.
It has the latest firmware V1.06.
Reading the threads it seems many are still having similar issues with this Orion Charger. Can you please advise how to rectify it?
I look forward to your response.
