clearly ...

That neat little program says I need 13.8aH of backup ... so thats what I will get ... in the form of 2x7aH ... 1 in PSU and the other in main panel.

Sounds good to me. And for a non pro carrying out this work fair play, because there are a lot of engineers out there that would have issues doing this.

Need any help please revisit.

Good luck bud !

Thank you! I appreciate that alot.

I'll be sure to keep everyone informed ... as I run into troubles along the way no doubt.

Just to stop you for a second.

Did you work out the loadings independently for the panel and PSU. As they will not be powering each other under a mains fail.

As you gave a total power consumption in your calculations.

cheers

No that was overall.

So the PSU is not wired into the Panel (for power sharing) its just A&B lines linking the two ?

May mean that I will need more backup power in the PSU than in the Panel.

Worst case is that I put the biggest physical battery I can in each of the Panel and PSU.

your 1A galaxy will only support a 7A/h however your 3A smart psu will support a 17A/h

I would load the panel the lightest so that the smart ran out first. YOu can use that application of ours to work out the loading accross each supply
