Hiya, I have a Aurora 5000 solar inverter installed by energy matters, it was filthy so I switched off the AC Isolator switch and hosed around it (not on it) and gave it a wipe. I've since tried ever combination of switches to restart it (waiting 10 min plus). I've followed the dc on, ac on, order, double checked the fuse box switches, tried it with and without ac fuse on. I can't work it out. I didn't turn off the DC isolators when I cleaned around it, just the AC.
I climbed the roof and looked at one of the rooftop isolators and it is in the on position.
What have I done wrong?
