Have you ever installed and connected a Hybrid inverter?
Post a sketch so we can see how you separate/isolate the inverter input, when in bypass.
I have been going through many sketches and they all seem to have the power to the mains side of the changeover switch and the inverter input connected together, which effectively would still provide power to the "input" inverter when the system is in bypass.
The only way to isolate the inverter when in bypass, would be to do what I do is fit a double pole combo mcb next to the changeover switch, which must be switch off when the switch is in bypass otherwise there is still power to the inverter input.
To complicate it even more, throw in a hybrid inverter which is connected to solar panels. Its becomes a complex switching operation, which could explain why this such and important topic.
Just to complicate things even more, add in a neutral/earth bond relay
I believe it should be law to have a laminated isolation sheet installed on or next to the inverter as well as all the correct labels. It doent help just having labels.
I went to a site a couple week ago and I battled to figue out how to make the installation safe enough to work on it, and I have been doing a ton of research, installed plenty of standby inverters and work in the electrical industry.
A brief description would make life a lot easier. Some might say you can just phone the installer, when those start boiling and and gas starts spraying all over the place, it is better to have an understanding of how the system works, not everyone is a DIY solar expert.
