Solar Panels Query

[Bjm]

hi, this is a discription of my system

i have a solar system installed and supplied free, they just keep the feed in tarriff and i get the electric during the day free.
i only mention this because i feel a lot of people may go this way, but the operation and output of the solar panels are monited remotely, so that if theres any problems they can arrange a call out.
the monitering can be done by one of two methods. using a built in sim card that regularly updates the control centre at predetermined times.
the second way uses a radio signal that is sent to the next solar fitted house, then the next and so on, when it gets to the last house in the loop that will contain the sim card control unit that reports to the control center, (note that is only solar fitted houses using the same company, and does not apply to privately fitted systems)
this means that if you mess about with the system in the wrong way then the company will be arranging a call out.

They have installed 18 solar panels, two banks of nine, each bank connected in series and the two banks connected in paralell. the panels cables run into the loft to an isolation switch before entering a pv controller and the grid tie inverter (which are modular in design, but under one cover and look like a single unit. the cables then run into another isolation switch then the mains.

the way the system is put together does have some flaws that would allow a feed off, or/and a system put in place ready to use when the shtf.
the trouble with having a feed off is that although it can be done covertly you would have to be willing to reverse it back to normal if they ever needed to do maintenance on the system during the lifetime of the contract.(this is i am told rare and they do arrange a day to call and dont just turn up) but a system put in place is fine and can be set up and connected when the grid goes down for good.
as said in other posts the voltages involved are deadly and not to be played with unless you have an understanding on what you are doing. and the way my system is set up may not be the same as yours.
