What should I ask the #solar installer who is coming to do a survey tomorrow?
I'm intending to ask for a Sunsync with no connectivity (other than the 485/modbus socket so I can drive it myself).
Things I have on the list:
* Confirm model of inverter/panels/etc
* Check they do the DNO/G98 stuff
* Check bird protection included
* What electrical work is need…
