Well, you already have the batteries, so first thing you need to do is read the user guide here -> http://www.exide.com/Media/files/Dow...aintenance.pdf
I am assuming these are new batteries from what you wrote. However you have no history with them. What was the manufacturing date on them? Make sure they were not old when you bought them. You say you charged them. How did you charge them? With what charger? You should use a three-stage charger. The only way to know if the batteries were really charged is to measure the specific gravity. Did you do that? Get a kit and make sure all the cells charge within the spec in the guide from the link.
I see others have done the calcs for you. There is no way to get 50 hours from that battery or charge from those panels.
But first, take care of your batteries. If they are discharged to the point that the inverter shut off, then they went too low already. Charge them properly and test the SG and see if they are still ok.
