There are a number of local manufacturers of prepaid meters in RSA. To get your meter into the market, you going to have to submit it to SABS for testing, and then get SANAS approval, irrespective if you have other testing laboratories certification. You then have to look out for tenders, in which the meters are requested.

Too much hard work, jumping over hoops and other necessary requirements in my view for this extremely competitive small and closed market.
