Try it with just an MCB, if it works its more likely to be a wiring issue than a faulty inverter.dlw wrote: ↑Thu Jun 19, 2025 7:58 pm Yeah I was surprised, maybe because I put the installation date as tomorrow even though I've been doing it on and off all week.
But I have a problem, went to power up the inverters and the one I had delivered a few days ago is DOA, turn on the incoming power and it trips the RCBO instantly, swapped locations with my other inverter in the fuse board to confirn it wasn't a faulty RCBO and it did the same thing![]()
Now I have to wait for Bimble to get in touch with me, I sent an email to support and an hour later (out of hours) I received my invoice![]()

Just watched the video and it makes complete sense now, I'll ditch the RCBOs and fit an MCB, probably not a faulty inverter thennowty wrote: ↑Thu Jun 19, 2025 8:27 pmTry it with just an MCB, if it works its more likely to be a wiring issue than a faulty inverter.dlw wrote: ↑Thu Jun 19, 2025 7:58 pm Yeah I was surprised, maybe because I put the installation date as tomorrow even though I've been doing it on and off all week.
