I have that but am unsure how the setup will be on the trailer though. Or how I can use their set up and add too it.

Any reg supplied stuck on the back of the panel is going to be cheap junk & is best replaced. Even if it was any good, which it isn't, being stuck on the back of the panel is not a good place. It will read the output from the
the panel rather than what is actually reaching the battery, which is likely to be less because of cable losses. A better quality regulator would treat your battery better & help it last longer.
The Repco charger, if it has a 240v lead is a mains charger, intended to be used where you can plug into mains power (i.e.. at home or in a caravan park). It may be convenient to retain the Repco mains charger, but it wont do the job of an in car charger, (dc to dc), nor will it do the job of a solar regulator. The BCDC1225 will do both, do it well, & provides an 'elegant'solution. You could leave the regulator on the back of the panels for emergency use should you ever need to get some charge into another battery like Kallen suggests. Just disconnect it & reconnect should you ever want to use it.

I dunno cuppa as this Repco charger did have a connection on it to connect up an Andersons plug and lead to charge from the car aswell. So it can charge both via the car and 240v. How I would add a BCDC1220/ 25 into the mix is another question.... Still trying to find specs but the Repco site doesn't show squat.

All it says on the trailer spec sheet is 12v/12Amp 240Volt Mains charger....Why doesn't Repco show any specs of their products on their website. Hopeless.

I'm 99% sure it'll just be a mains charger. A 12 amp one for a 12v battery.
If I'm correct there is no reason why you can't connect the BCDC to your battery as previously mentioned & leave the Repco charger connected to it as well. Plug in to the mains when available, charge whilst driving, & connect solar when camped out in the bush. Use the mains charger you already have at home to charge your crank battery (& aux battery via the SBI12).

Yea fair call on the solar panel reg guys.
You mention you wanna sell that Anyway mudski so yea, 1225 it up and grab an unregulated panel, will be cheaper..

But running the repco 240v charger and the redarc side by side is easy.. You just connect both to the battery..
If your worried about back current into either of the 2 chargers run either isolators or plugs on the battery side of them but I don't think that's necessary.

Unless they are using this Repco jobbie just for mains and nothing for 12V??? Direct from the Anderson plug to the trailer battery? Might have to wait until I get the trailer maybe to see exactly.

If its a mdc trailer its a 240 - 12v charger for caravan parks and storage as a mate has just bought one .
