Sorry for not getting back to you sooner on this, but we've been moving into the Chicago office all week and I just saw your message. Any pictures that you could provide on the inverters, dry cells, voltage stabilizers and charging stations would be very helpful. If you also have any drawings of how the systems were laid out and would be able to copy those, that would be a great help as well. We recently updated the Power Peripherals project page with a few more detailed projects so if there's any on the list that you'd be interested in getting more involved in, just let me know. One thing in particular that we're working on is a comprehensive "Power Deployment Guide" for people interested in providing power to XOs at a school with either limited or nonexistent grid power that lays out exactly what they should consider based on their deployment size, location and available resources. It would be great to hear your experiences with different power delivery systems in Nigeria and any issues you may have seen with setting up these systems.
