These are approximate, but I think a typical charging voltage is around 14.25 for lead / acid. AGM could be damaged at that level so I think the typical voltage there is about 13.8.

It has been a while since I reviewed my inverter book, but it goes into some detail. I think you might be able to do a web search also.

This site is a good starting point, and I think you can link through it to other sites to expand the information.

Charging protocols are part of the inverters and on mine a set of dip switches on the back of the panel are the only things that have to be set for specific batteries. The rest of the regimen is taken care of from that point on so you don't need to know the specifics.
