[RE-wrenches] Charging two battery banks

[Dave Angelini Offgrid Solar]

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.

Dear
people: 

I have a customer with a solar array for his 24V system, Bergey
Excel 10 wind genny, 12KW Kohler generator, two Outback controllers and two
FX inverters. 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? 

Best, 

Chris Daum
