## Questions & Answers

**Q: This unit has been triggering my RV's low voltage proection, likely from random spikes.  Anyone have an idea on how to disable it?**
A: Yes, the same thing happened to me with my 30A Victron dc-dc on my 2021 Ford Transit starter battery.  The answer is to use the 18A victory dc-dc charger.  I learned this the hard way. Some cars can't handle that draw.

**Q: Would it harm this victron 12-12-18 if I mounted it in a pickup truck engine  compartment, connectors at the bottom and air space around it?**
A: For good cooling effect, the Oion is designed for vertical mounting only. Other mounting methods may impair cooling and reduce the service life of the product.

**Q: Can I connect the input and output ground together?**
A: Yes if not trying to isolate like in a boat for galvanic corrosion. If you don't need the isolation feature just purchase the non-isolated model and save a few dollars. If you already own the isolated model and installing in a RV you can ground both to same ground connection.

**Q: I'm looking to find a dc-dc charging solution that also accepts solar input.  i'd rather have victron vs redarc or ctek?**
A: I use two separate devices.
Solar is in series so the input ranges up to 100 volts.
It’s nice seeing both via Bluetooth.
