Help setting up Orion DC-DC

Hello everyone, This is my first post so please be nice! :)


I have a 2018 Transporter Petrol and have installed a orion smart charge to charge my 120ah AGM leisure battery,


I have placed the unit in charger and mode, and selected "agm" battery type but my unit will not charge my leisure battery. It just comes up bulk charge.


Could someone help?

There are different charging modes. Not sure if all apply to your unit. Bulk is the first, followed by absorption float and storage. On initial use, bulk may stay on for what seems forever. Then it will stay another eternity in absorption. Think of it as finishing off the last bits of charge. Float is maintaining the charge level and supplying any 12V loads. Storage is you haven't used it for ages, bartery is full, I'll take a nap while I keep an eye on things.

As soon as you use the battery, the charger will kick in.

Vehicle battery - positive cable through van to positive input on Orion

Input earth to chassis ground

Output positive to + leisure battery

Output negative to - leisure battery

from leisure battery to 12v fuse board connecting lights/fridge and battery monitor that is showing the battery is not charging even after 2 hours of driving

Show us the initial screen with engine running. If it always says bulk and its not charging then its faulty unit or your battery is no good.

If it is actually saying in the main screen charging is disabled due to lock out voltage etc. If its a smart alternator you will have to tweak lock out voltages and engine running detection or run a wire from ignition to "remote" as per manual.
