Opinions on my battery charging profile (solar)

I guess nullifying the 14.4V is what I'm trying to do since "they" say that 6V batteries in series should be charged at 14.8V because Trojan says so. But since always charging at 14.8V would mean my inverter won't turn on, I dial it back to 14.4V but try to sneak a 14.8V+ in there on a relatively frequent basis.
