I've got a very large 3 phase solar panel setup in the field next to the house. Its a bit of a mish-mash of old and new, the new bit being a 3-phase 30kw inverter. The sunny days recently it's been running at close to 100%. Here's the screen:
Now - the problem. Onto the terminals for this, I've attached a thin rubber cable and a socket - just to run a little camera. Should all work I think... but apparently it has other ideas. When I connect the 12v 1.5a power adapter (18 watts) it causes a massive voltage drop on phase-1 causing the inverter to turn off. Voltage goes from 248v down to 123v. I don't get it! surely the voltage drop would just be to the device at the end of the thin wire.
I am puzzled - can anyone explain the physics and what on earth could be wrong?
One more detail - I have another little socket at the mid point - the 'outdoor junction' also on L1+N and the power adapter works fine there.
