I would say in general, if you are series stringing modules , current mismatch is really bad and voltage mismatch is not an issue. The current in a series string is limited by the lowest current in the string and voltage will simply add up. Just the opposite when paralleling strings. Current

Hello, Looked at a system today that consisted of the following: 15 - Kyocera 158W modules 3 - Kyocera 185W modules 1 - Outback MX60 8 - New Trojan L16RE (48V system) 1 - Xantrex SW Plus 6 months ago he swapped out his old charge controller to the new MX60 and purchased the new

Hi Jeffe, I don't know the specs on those Kyocera, but if they are the same VOC then they are fine together. As to a enclosure for the CC's, I'd look at Midnight. They have about a million different boxes, you'll find one that will do the job for you I'm sure. Depending on the area, you might

Jay , The modules have different electrical specs... I'd like to use the midnight because the new array in series is at 148V. We see -40F. He already has the Outback 60 on site. That's why with 2 existing outback products I figure the Flexware route would work best. Thanks! Jesse Sent

Not sure what this is worth, but with most Kyocera modules that used the same size cells (but different amount of cells per module) you could wire many different VOC modules in series as long as the total number of CELLS per string was the same. It wouldnt matter what the individual module ratings
