AC200L connect 12v fuse box

Product Discussion BLUETTI AC Series

Hello,

Changing from an AC200MAX to an AC200L. Using this in our van as primary power source.

With the AC200MAX, we used the 12vdc/30amp port to connect a 12v fuse box.

With the AC200L, can we use the 48V/8amp port to power the 12v fuse box or will we blow fuses OR do we need the D40.

If we use the D40, do we need a fuse (if so, which one) between the D40 and the fuse box?

Thanks!

If your original system is set up for 12VDC devices, then that is what they will continue to require. If you give those devices 48VDC, you will likely destroy anything you energise.
The D40 is primarily a multi chemistry battery charger, however, if you set to load mode it outputs 12VDC @ 20A and then can be connected to you 12VDC fuse box.
You definitely need the D40 to use the 48VDC port of the 200L.

  1. You need to pay attention to two parameters when buying fuses, input current and voltage
  2. Only with D40 can you use the RV output port of AC200L.
