At the moment i have a BP solar regulator (10 to 15 years old) on my Camper & is connected to the on board single battery.
The regulator has the following terminals -
Array + & -
Batt + & -
Load + & -
Sense + & -
Now obviously the solar panels connects to the array terminals but my question is if i was to connect a 240v batt charger to the system before leaving
home can i connect it to the array terminals with the solar panels disconnected ?
Thinking i then have two regulated devices before the battery.
Id prefer to leave the actual battery & box alone & connect to the regulator termination box & i can connect the 240v charger directly to the batt incoming cables but it would be a lot easier to connect to the array terminals.
Have i confused anyone ?
Any ideas ?

NO !
Most solar regulators short out the panel to control the charge and this would blow the charger.

Ok! smartypants.
Why didn't you tell me that 6 days ago and I wouldn't have blown the a r s e-end out of my $m+ Plasmatronic PL-20 at 2.00am 'experimenting' with a 'test run' with no sun.
I tend to fly by the
seat of my pants and learn the hard way (Expensive way also) I just have to laugh and thing to myself -
well now you know you f***wit, don't do it again (LOL)
Good move in asking first Kev.

Connect the charger to the battery terminals of the regulator if you can't get to the battery easily.

Well thats a definite answer, I didn't know that.
Sounds like you know what your talking about so i will take your word for it and wire the charger to the batt terminals.
What beats me is why it has sensor terminals when it could be just looped across to the batt terminals. Voltage drop i suppose.
Thanks for your reply mate.

why do you need to charge a battery with 240v when you have a solar system ???

Basically to keep it charged while sitting at
home, easier to plug in the charger every now & then than to pull out the solar panels.
(not connected to the car charging system either)
