Long story short - I have a master/slave inverter setup and I don't have the flex ribbon cable to connect them.
The ribbon is one of those super flat, 11-pin connectors which apparently operates at high temperatures (it sits over the back of the panel - so I imagine it gets pretty hot there).
The inverters have quite large copper circles/pads that connect to each pin of the connector - I assume so the engineers can easily measure readings on those pins?
So I soldered some CAT5 to the connections - as it turned out only 8 of the pins were in use, and then 9th was a ground, so I just used a bit of speaker wire.
I used a longer piece of cable than the original ribbon, so I could route it differently (so it didn't get as hot) and the outcome was that it didn't work - neither inverters switched on.
I'm wondering :
- Would the extra resistance of the longer cable, and thicker cable screw things up?
- Would the twisted nature of CAT5 screw things up?
Is there another solution to this problem - such as a cheap way of buying a generic flex ribbon?
