<p>Hey folks,<o:p></o:p></p>
<p> 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.<o:p></o:p></p>
<p> Would love some input, thanks,<o:p></o:p></p>
<p>Bill<o:p></o:p></p>
