[RE-wrenches] High-power MPPT/Charge Controllers?

[Darryl Thayer]

Hi 
I have a system in operation since 2003 using 13 paralleled Outback MX 60 CC and I have measured over 600 Amps at 48 Volts.on the common bus.  Outback and I replaced the fans in the MX 60s but we have had no failures.  This power is converted to 60 hZ using 12 Outback inverters, I have had an inverter trip off on the DC side just the other day and I will check it out this comming week but no problems.

Sounds like a project for Sunny Island and the Boy's.
