bcdc1250d wiring diagram

I noticed the wiring diagram has no fuse on solar input. Does that mean I don't need a fuse there?

Also the wiring diagram includes no voltage sensitive relay (though I think some of your other wiring diagrams do include a relay). Does that mean I don't need a voltage sensitive relay with bcdc1250d?

Are the thick wires that come out of bcdc1250d 6B&S?

Hi Paul,
Thanks for your post.

In general, Solar would not need a fuse unless you are wiring in a big array. This is generally only caravan/RV type installs so shouldn't be a problem in a 4WD type setup. If you do want to put one in however, no issue there. Just ensure it has enough overhead to handle any spikes from the output (EG use a 20A fuse for a 10A output panel).

No VSR required with these units, all the switching is done internally and will cut in/out as needed. The older BCDC1225 and BCDC1240 units did have a change-over relay previously, but the current model 'D' range do not need this.

And yes, it is 6 B&S cable coming out of the unit. You will definitely need this, or thicker depending on your length in cable run.

I trust this has answered your question in full. If you are still requiring assistance, please call us on REDARC Tech Support on 08 8322 4848.

hello I've just purchased the bcdc1250d and wondering on a thaught ,i have 2, 138 deep cycle agm battery's, 1 in a battery box with a 160 watt solar panel running thru a mttp second deep cycle battery is connected to battery box via a Anderson plug and seems to charge ok as the battery box charges .. now my question is can i connect my bcdc1250d to my second battery and will it work ok and charge ok when driving or engine running as sometimes i need my 5,000 watt inverter for power and want to be able to charge battery's up fully after use and if night time solar is asleep.. oh and could i also run a unregulated solar panel thru the bcdc to secondary battery if needed with no conflicts with other panel , thanks hope i didnt confuse you..
