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

Re: [RE-wrenches] High-power MPPT/Charge Controllers?
Wow! The most I have in one Outback install is 8 MX60s and 8 VFX3648s. Overall the customer has been happy with the performance and the stacking power save feature helps with idle power draw. As for the OPs request, the most PV still remains to be about 5000 watts gross power per controller (80A x 50V / 0.80), even if they slice it up as high voltage or not high voltage type controller. Another curious idea is the cost per volt when comparing 150V input, 80A Output controllers to the new high voltage input controllers. That cost consideration spreadsheet is still under construction.

Dan I just stacked 5 Xantrex XW-MPPT-600-80 controllers with 10 strings of 10 in series 225W modules (2 strings per controller). The XW PDP accumulated all this wiring to battery back.
