Fellow Wrenches,
I realize that many of you are offering your time and comments in a genuine
effort to help Ron, however, the problem he described is the EXACT behavior of
all early 3024i controllers. This happened with overloaded controllers
operating in 24 to 12 downconversion, just like in t
he entire PV.
If this is the case, ensure the diodes are more robust than the
parts used in the original product, and that all connections to
the new parts are solid.
Regards to all,

Ron et al-The firmware in the controller sounds likely, but a faulty shorted bypass diode does not. Isn't that what bypass diodes are supposed to do-- turn on and short (bypass) a shaded row of cells?We use to see this half-panel voltage as a failure mode with the old Kyocera 120's when they were s

Ron,
It certainly sounds like a failed diode (there are two) to me. Usually they
fail open, but it isn't unheard of that they might just avalanche when they see
the current of the other PVs. Solarworld would probably replace it under
warranty IF you return the dead module to them. How the hell d
Hi Ron,
The problem you describe is due to the firmware in very early versions of the
3024i. What would happen is once you hit the 30 amp current limiter, the
controller will switch the input to act like it is connected to a nominal 12
volt module, lowering the input voltage. Contact Blue Sky f
Hi Wrenches,
Wondering if anyone can shed some light on this. I have a customer who self
installed 4 x 165w Solarworld panels a few years ago (2008). It's a 12v nom.
battery and the panels are wired in parallel. They've been working fine for
five years on a full time household using a 3024i Bl
