@PaBz0r maybe post some graphs from VRM so we can see what's happening at the time of overload? Edit, sorry I see you did 😊

Then I do not know 🙂 I still have overload warnings at night, with low load - suspect this is due to a long cable to the inverter. Similar to this: https://community.victronenergy.com/questions/35581/constant-overload-warnings-on-multiplus-using-ess.html

@PaBz0r - do you have the South African grid code applied, and how long is the cable between inverter and distribution board?

Including grinding the tile if you need to etc.? Sorry, forgot to ask.

How much more work is it to install roof hooks compared to using the straps, out of curiosity? Trying ot understand why you'd use the correct rail, but not the hooks.

@plonkster The rails that were used:

@plonkster this is just visible below the panel's edge

@plonkster - that is what I thought as well. Unfortunately only noticed this afterwards <sigh>

I had 4x 405w panels installed on a tile roof (see below for what roof looks like). The installer did not use tile hooks to attach the rails to the roof, but rather some kind of galvanized steel strap. As far as I can see the strap goes under the tiles and is attached to the rails with screws. The result of this is that the rail lies on the tile roof, but you can move the installation up and down because of the use of strapping instead of tile hooks. Is this a common way to install the rails?

I don't think you need such a complicated diagram; did they specify what it must look like?

I am using 8 "old" UPS batteries as well, and will give some feedback tomorrow.

If you take 9 months to get something like that approved - how many people will actually follow this process?!

Who can wait 5 months just to get permission to install? What was the supplemental contract about?

How long does it then take, from the first piece of paper, until connecting to the grid?

15 months 🙄 That is a ridiculous amount of time to wait.
