Chris,
When I do this for a client, I add a second inverter/charger and make a completely redundant system. This way it can be powered from the DC bus or AC trickle charged which is very easy to automate.

He currently has a set of the Solar One SO-6-100-33/24 batteries, which have maybe a year or two left in their life. What he would like to do is add a separate battery bank - perhaps a set of LFPs (like SimpliPhi). He wants a set up where, when his Solar One batteries are full, the excess voltage 'automatically' charges his secondary battery bank. I am wondering if a dump load controller would suffice (so when his Solar One batteries are full, excess voltage is dumped to the secondary battery bank), but I'm not getting much help from any manufacturers as to what might work. Any suggestions?
