<div dir="ltr">Hi Bill, <div><br></div><div>Those SMA inverters can handle a max Isc of 18A. Check your module datasheet, but I would assume that you would be under this limit.

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