MX60 w/ a DR2424

Post by Christopher » Thu Jan 16, 2003 5:04 pm

The CCB bracket works on either side of the PSDC and yes the DRs mount on the opposite side from the SW series inverters. The OutBack FX2000 can be mounted in either orientation BTW.

The negative conductor from the PV array can be wired directly to the negative bus of the MX60. You only need one wire from the negative DC bus to the MX60 and it can connect to either of the DC negative terminals (they are common). The open DC negative can be "daisy chained" to the other MX60 if you want to but it will look odd and might raise a few questions from an inspector.

Thanks for the questions! [img]images/smiles/icon_cool.gif[/img]

<strong>A need to attach two MX60's and a DR2424 to the PSDC. It seems like the input for the DR is on the right side of the PSDC as you look at it. Can the charge controller bracket and 2 MX60's be mounted on the left side?

Also, in another post it was mentioned that the negative from the panels does not need to be connected to the MX60 and then it was said that they can be daisy chained. Does this mean a seperate negative isn't needed or that we can go straight from the array to the negative bus bar as shown on the sample system in your PDF files?
