On a three-input inverter, you could have as many as 6 strings of modules, 2 per MPPT input, and you would not need any overcurrent protection on any of the strings.</span></p><p class="MsoNormal"><span style="color:#1f497d"> </span></p><p class="MsoNormal"><span style="color:#1f497d">One of the beauties of inverters with multiple MPPT inputs.
