The Orions are great DC-to-DC's. Their one drawback is that there is no way to configure a current limit for the device. It will always try to push its maximum current if it can.
@@russelllang2910 Yup, indeed. I forgot about the XS. Pretty expensive at $330, but a capable unit. Wish they'd do something more general for both the input and output voltage range with the XS. I barely ever use 12V anymore myself.
Maybe I misunderstood what you were hoping to achieve but it sounded like you purchased the wrong model Orion, Isolated insteand of non-isolated. In any case, regardless of the model as long as it's setup correctly, I've been very happy with my Orion dcdc. The unit is under specified whereby I have seen it charging at 35 amp even though it is specified as a 30 amp charger. Of course there is a 50 amp version now which would be ideal for a setup such as yours. In my case I only have 170AH of battery capacity and the combination of 30 amp DCDC with 200 watts of solar via Victron MPPT charger provides a consistent power supply for my application. Thanks for sharing. Cheers from OZ
Most of the time isolated isn't required, but can be useful with trailers. Here is a quote from an EE on the topic: "Galvanically isolated is a nice thing to have, especially if you are charging house batteries in a trailer from the tow vehicle engine. The issue relates to how the house battery is grounded to chassis ground when the tow vehicle is disconnected."
@@cyclemoto8744 ground as in "NEG return" in the DC circuit. DC-DC chargers require two POS connections by necessity (in from alternator and out to battery bank), but usually only one NEG connection. The isolated version is useful when there is not a unitary NEG available: disconnected trailers, fiberglass bodies, etc.
On load it says it pulls out 7.8A. We have never had a problem with amp draw with this unit. We are on our third year with it and still are impressed with the amount of water we pull out of the air. I hope that helps. Thank you for watching.

The newer Orion XS allows you to set a maximum input and a maximum output current.

@@russelllang2910 the XS is non-isolated. Not a good design for truck campers or travel trailers.
I definitely want to get one of these, and I’ve always wondered about the installation. Thanks for the detailed video!
Like we said we ho-hummed over it way too long. We should have done it years ago. It really is an easy instal. Thank you for watching.

@@fratermus5502 Am I correct is saying that you're referring to the ground related to the AC circuit for an anboard AC charger ? Cheers

@@fratermus5502 I get that but this can be overcome by adding a dedicated neg circuit in the trailer instead of using chassis grounding. Cheers
How much electric draw does your DEHUMIDIFIER take?
