For those waiting for V2G... i found that Vector has an EV V2G inverter on the approved inverters list now
Though it seems in 2018 this inverter cost about 10K so the economics are not really there unless the price has come down significantly.

Hopefully it doesn't need a visit to change the voltage parameters? For Fronius, you can get to the local configuration interface through solarweb. Settings -> Components -> Inverters -> Actions -> Device Settings
That is just the same as going to the local IP address of the inverter.
You need the technician login details to change some parameters and the most parameter, access code for country setup password to change the rest.

That was one of the first and only chademo based one that came out. now days its all CCS based.
Would love to see one via the AC port but i suspect the issue with that is there is no 2-way communication there.

I've got three strings on the roof, each with a twin 4mm cable running in a shared 32mm PVC conduit.
I'm looking to add another string.
To save me having to get up on the roof to take a look, is there any chance I could draw another twin 4mm through to add cabling for the new string.
The tilt and orientation of the proposed new string means I cannot extend an existing string and as the house is concrete I'd prefer to not have to drill to install more conduit.
You'll hopefully have room in the 32mm condu for another 4mm twin . My installer ran 25mm condu - was a tight fit to cram in 3 x 4mm twins + ground. 32mm has almost double area
25mm conduit
A=π×(12.5mm)2≈490.87 mm2cap A equals pi cross open paren 12.5 m m close paren squared is approximately equal to 490.87 mm squared
𝐴=𝜋×(12.5𝑚𝑚)2≈490.87 mm2
32mm conduit
A=π×(16mm)2≈804.25 mm2cap A equals pi cross open paren 16 m m close paren squared is approximately equal to 804.25 mm squared
𝐴=𝜋×(16𝑚𝑚)2≈804.25 mm2
