Hey folks,

                 A customer I installed a system for 18 years ago now 
wants an upgrade, partly due to the Mitsubishi 170's high failure rate 
and the purchase of an EV.  The Mission PVs I'm looking at (at a deal I 
'can't' refuse) have a rated current of just over 13 amps, a string of 
10 is easily below the Voc limit. The specs for the SB6.0-1SP-US-41 show 
a max current per mppt of 10 amps.  I've never "pushed" this max amps 
limit quite this much, is there a problem?  I assume the inverter will 
just clip the input to 10 amps midday.

         Would love some input, thanks,

Bill
