[QUOTE="Bob Smith, post: 540884, member: 35176"] Hi, I am getting increasingly confused and puzzled by the minutes between the DNO and the installer. Hopefully, your wise guidance will help me to see more clearly. Quick recall for those needing a catch-up I currently have a 4kWp facing SE with FiT I am planning to: add 11kW of panels over 4 different locations (7.1kW NW, 1.3kW SW and 2.75kW West facing but on the gable) Start with 10kWh batteries Batteries to be changed from the existing 4kWp array + the new panels A request has been made to the DNO for an 8kW hybrid inverter Now, the DNO apparently asked to reduce the array to 17kW. I asked where the 17kW came from and the reply was the installer is going to resubmit the application with a new inverter design and that basically, the DNO are including the battery system as part of the generator and thus judging the system size at over 17kw. Btw the DNO is Scottish Power. Why are they including the batteries when the export bottleneck is the inverter? This would also mean that every time I want to add more batteries I need to ask for the DNO's approval. I never came across this. I would really appreciate it if someone can guide me on how I should respond. To me, this is not right but I have no ground to defend my feeling. Thanks a lot PS: I have not seen the design from the installer. We just discussed the equipment so I do not know what he actually submitted. :( [/QUOTE]
