The technical aspect of registration seems to be pretty much the same everywhere. All other municipalities are largely basing their policy on COCT, and COCT is based on SANS (I think it's SANS, some standards issuing body). What is different from city to city is the red tape and which queues you have to stand in in which buildings.

The technical checks are mostly safety. This includes correct identification of breakings, and warning labels in certain places so that an electrician (municipal or otherwise) knows that they are dealing with multiple sources of power (this was the only point I failed on, but it was easily rectified).

I worked with a company named Pure Energy. You can email them on [email protected]. They tell me they do registrations all over the place, and they certainly seemed up to speed not just on the technical side, but also in terms of the municipal processes. In fact I signed a letter early on that granted them authority to act on my behalf, and they then took care of all the paperwork, the setting up of appointments and etc. If your time is worth something to you, then this sort of service is worth checking out.

Sure it cost me a few K, but it would have cost me a few K anyway to get an engineer (and it must be an engineer) to prepare the drawings that are required (Pure Energy did this as part of their service). It would have cost me to stand in queues at offices all day. So I regarded the money as well spent.

Also they should be able to advise you RE the meter, if it has to change, who bears the cost etc. 

NB! They are not going to fix any defects they find. They will just say that such and such is required and that's up to you to get done at your cost.

I only have 1 ct coil and it was installed in the inverter where it unscrews. They moved it to the new ac db box where the switch is to move it up for eskom or down for solar. The slave shows zero input. Moving it made no difference but its far from the main db.

Switch on a low load. Switch the grid off and post the system stats screens for both inverters prior to grid off and while the grid is off. From this one might pick up the reason. 
This is the screen that shows all the instant values from grid PV battery and UPS load. 
Don't want to start guessing without readings.
