[RE-wrenches] Helping/Advising on a Project in Mali, West Africa

[Ray Walters]

As long as the PV is going DC through a charge controller direct to the 
batteries, there's no reason you can't have 2 separate inverters on the 
same battery.  I've done that before.  Just be careful with grounding 
and bonding. I've done a fair share of aide work over the years, 
including Tanzania, Haiti, Puerto Rico, and Morocco.  Drop me a line if 
you need any help.

Thanks,
