<div style="direction: ltr;">Gary- I am assuming the array is 600v based on string length. Perhaps a few more of the 33kW CORE1s might be a better design fit - could they be mounted off the ground at the combiner locations? Then you utilize 8 of the 12 inputs
of each inverter. This would require a couple more conductors go to each inverter location and become AC homeruns to an AC collection panel at Satcon location. </div>
<div style="direction: ltr;">The CORE1s cannot run multiple inputs in parallel mode as the A and B channels of the current Sunny Boys can, so I think what you are trying to do will not work.</div>
<div style="direction: ltr;">Feel free to contact me directly if you want to discuss further.</div>

<div dir="ltr">Hello Wrenches
<div>We have a project taking a 480kw carport array feeding a Satcon 500kw inverter and upgrading it to 8- 50 kw SMA inverters. The SW 285's, in strings of 12, are combined in groups of 8 in the field then fed to the inverter DC input. In my experience SMA
sells a rapid shutdown box with 4 inputs but only 2 outputs to pair with their Inverters that have 3 MPPT channels and they instruct you to combine the strings at the rapid shutdown box on the roof then install a pigtail on that wire at the inverter splitting
it into two and sending the output of those two combined strings into two seperate MPPT channels. We would like to do the same with combiner panels in reverse. I spoke with SMA and they are checking with Germany but I knew I would find info here. Anyone
with experience with this? <br clear="all">
