Connecting battery charger/battery/inverter systems to the Eskom grid supply, as suggested by Michel Melengret, should be prohibited. The only exception could be for uninterruptible power supply systems, but then for computers and emergencies only. The use of this type of sys-
tem as a backup for Eskom failures is most wasteful. During the last few months, hundreds, if not thousands, of these have been installed in mostly well-to-do households at enormous cost). But do these owners and installers (and Melengret) realise that, once Eskom sup-ply comes back after a power failure, the batteries have to be charged up again? They are, in other words, stealing power from other consumers. This extra load might cause the next power failure or load-shedding. Intelligent control, as Malengret suggests, as a way to recharge batteries only at night, is far fetched and non- existent in the hundreds of systems installed lately.
