B to b charger.

[Wherearewenow]

Hi all .i have a victron b2b charger(not blue tooth one)12/12.30. How much charge should it be putting in my victron lesuire batter when driving..is there any way I can turn the charger up for more power.as I have seen a little screw underneath the charger with a plus and minus arrow..any help would be great as we're going to have to park up for a couple of day with the winds coming,(we are at wick Scotland at mo..thank you...oh solar not drawing much power cuts cloudy..thanks

Providing it has been wired with the correct size cable it should charge at 30 amps, no mention of any adjustment in the manual.

Bit of confusion here ...... What is generally referred to as a "Victron B2B Charger" is the Orion-Tr Smart DC-DC Charger. This is ONLY available as a Bluetooth enabled device. What it actually sounds like is an Orion-Tr DC-DC Converter - quite a different animal.

The Orion-Tr DC-DC Converter outputs a set DC Voltage, and what the little screw will be doing is increasing or decreasing that set Voltage. the default output voltage is just 12.2V so if it is being used as supplied, it will not be doing any battery charging unless your leisure battery is pretty low!
TBH, it sounds like you have been sold the wrong device! the Orion-Tr Smart can act as either a DC-DC Charger OR a DC-DC Converter, but the Orion-Tr (non-smart) is a DC-DC Converter only.

That explains why I could only find the Orion with Bluetooth, I assumed the OP just had an older model.

I think Victron are generally phasing out non-Bluetooth versions of kit, which is why certain models in a range are Bluetooth only as they were introduced AFTER that decision.
The DC-DC Charger is one example; the MPPT 100/20 is another one - the newest MPPT in the range of Smart/Blue MPPT Solars and available as a SmartSolar only.

FWIW, I use an Orion-Tr Smart as a DC-DC Converter rather than the NON-Smart version as it is so much easier to configure it instead of messing around with mechanical adjustments (they are also much easier to get hold of! the 12-12 Orion-Tr is a rare beast and generally ordered by mistake!)

Thank you for your replays and ( yes I've just had another look at the dc and it is a converter.(dam). Thought something wasn't right after driving a few hours and it still stone cold(school boy error,)looks like I need to buy a new blue tooth one.thanks for you input guys.

I have one if you want it...never used bought in error, and meant to send it back, but went away and forgot all about it, never been out of box.
Pm me if you want to make an offer no problem, Ill send dpd
it s the isolated version too https://www.batterymegastore.co.uk/...30a-360w-isolated-dc-dc-charger-ori121236120/

If you need to get some charge into the battery in the meantime, you can raise the output voltage - maybe about 14V would be right. But you will need a voltmeter to see what you are adjusting to (you can raise it to upto around 15.5V). But a multistate B2B is the way to go, and a Smart-Tr will be an easy swapover (except on the wallet!).

For us thick twits, what is the term 'isolated' referring to?

The Ground/0V/Negative (whatever you like to call it) is isolated between Input and Output on Isolated Chargers
Some people like to keep the Leisure/Hab electrics totally isolated from the vehicle chassis (or boat hull) and they would use an isolated charger for this. It is more common with boats, but a few think it is a good idea on vans.
It is much more the norm and standard to have the Leisure -ve connected to the Chassis in a van, in which case a charger being Isolated is irrelevant. You can still use the Isolated units with no problem though. I just connect the -ve IN and -ve OUT together (with the same gauge cable as the +ve IN and +ve OUT) to make it works as a non-isolated charger

That's good thank you (nothing to do with Covid then?)
