Mike Holt also explains this and has pictures of roofs that are destroyed

First of all correct your spelling errors. what is a neatral? When lightning strikes a building, it produces an enormous high voltage in the grounding conductors due to the inherent fast rise time of the discharge. Hence the high potential is developed between the system earthing and lightning protection earthing, which leads to cause unsafe situations for both personnel and other equipment connected. Another problem with an isolated ground is that the ground resistance of a system, which uses one or more electrodes, could be much higher than the common ground ratings. So lightning Protection earthing and system earthing should get bonded together in a ground level to make a low resistive path for all forms of grounding within a building.

This thread should be taken down

You made one hell of a scene , that's gossip for you

No naughty person, you will create a potential difference between earth spikes if they are not bonded. Let's blow the roof off ,jump ,jump

Master installer forgot battery fuse disconnect.

This answer is a non sequitur. I have been to the Victron repairs and its chock a block and not just Inverter controllers ,gx devices ,etc. The 8kw Sunsynk is a beast and there is nothing on the market that can compete for that price. Have done 20 8kw installs no problems, also when you start using smaller panels you can have 2 strings per Mppt and have something like 32 panels on your roof, if you have the space. Nothing comes close. In sunny areas i have taken people off grid with that 8kw and 20kw batteries.

Yes we must and there is Atess but I really can't find any reviews on that, so as long as the market is stuck at 48v we are stuck with expensive Victron AC/DC coupled for big systems.

I did thx and it seems like a great solution ,no reviews out on it though I see freedom won actually stock it and are compatible. Also a Chinese brand seems they are thinking ahead.

Hi I know an old thread I want to build a 90kw system 3ph this is usually done using Victron Quattro's and a kak load of mppts and wiring. The Sunsynk 8.8 manual states max 3 per phase but Deye video says 5 per phase, I need 4per phase. Has anybody attempted this. The other way would be HV battery and inverter but there are no good brands on the inverter side yet. Freedom won do high voltage batteries

I think for big commercial installations we must really change to HV batteries and high voltage inverters ,this idea of using quattro's and big bus bars and cute 48v batteries is an outdated idea . As an electrician who has worked with 11kv and 6.6kv i always have to laugh when i see 6 Quatro's and 15 mppts on the wall to get a cute 90kva ,ridiculous and unimpressive. The installs can be way easier and efficient using high voltage batteries and inverters.
