I'll get in touch with them about it and see what they say.
Luckily I'm in a rural area and on prepaid at the moment. if there's too much hassle from them I'll have to go completely off grid
ok I've found a regulatory site that shows the system I'm installing.
its classed as a standalone system as the two sources are not connected in any way
With all this talk of having to register grid tied solar systems, I am half way through installing an off grid system to run along side the eskom utility.
Basically I am installing a separate wiring run powering 5 sockets and the house lighting.
As these two are kept completely separate...
