Post in thread 'EG4 18K - What not to do in parallel' https://diysolarforum.com/threads/eg4-18k-what-not-to-do-in-parallel.84679/post-1105085!This is not accurate! The person who installed did not follow all the procedures in the manual and did not use the factory provided cable which is clearly labeled. The manual has no specifics listed on the interconnect cable, thus unlike *ME* the installer did not verify the cable pinout before substituting it with a different cable. Since the installer decided to use some random ethernet cable that happened to be a crossover it created an unusual fault condition that was not detected by the firmware, nor anticipated by the manufacturer. I would hold a manufacturer liable if they don't correct the documentation with a warning once they see the deficiency. If possible I expect a firmware or simple hardware fix to prevent this condition as quickly as possible now that the problem is identified. I would expect future revisions of the product to not allow this behavior.
If someone accidentally mis-wires something I built and it causes a problem I'm not the one who screwed up. Not too long ago, I inadvertently plugged a 110v/220v power supply into a 220 without moving the physical switch. I got magic smoke it blew up and took out something plugged into it. Not the manufacturers fault, it was mine.
This discussion is interesting because people keep intimating the "Professional" installer did everything right and somehow everything blew up. This is not what happened. The installer made a mistake, and it seemed to be working but his error caused the equipment to behave in an unexpected manner under some conditions.
It needs to be addressed for the future but the error was done by the installer.
Right corrected this in post 90.
BTW I only found TWO crossover cables in my bin of various network supply of cat5/6. One of them was indeed a short GREEN cable about 3ft, and another was super long (didnt want to measure) custom made (diy end connectors) WHITE cable my dad must have made 20 years ago.
