Yes only if you have a larger installation - my supplier offers a free export meter and installation.
Depends where you are - thought rather than clog up the GTI thread would post for info.
Thanks bbhs!
It may not be ralative to us USA guys but it was still a useful referance point! I learned a few new things related to what you have to go through now.
And thanks for not cluttering up the GTI threads! I do appreciate it! Hope your example is a good infulence on a few others!
