TheEnforcer Posted May 28, 2009 Author Share Posted May 28, 2009 The wrong buttons 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.

MattBaker Posted May 28, 2009 Share Posted May 28, 2009 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 !

Guest old-hand Posted May 28, 2009 Share Posted May 28, 2009 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. Link to comment Share on other sites More sharing options...

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. Link to comment Share on other sites More sharing options...
james.wilson Posted May 29, 2009 Share Posted May 29, 2009 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 securitywarehouse Security Supplies from Security Warehouse Trade Members please contact us for your TSI vetted trade discount.
