The questions posed by RE/backup power

My experience is that the providing for one’s own domestic power needs is quite a challenge. One has to do a fair amount of investigation as to what one’s power needs are.
One can be easily fooled into thinking that it’s fairly straightforward. However unless you are installing a mega genset to cater for your needs you will find the complexity of your power needs from a dedicated system surprisingly complex.

Once one “gets that”, the challenges, one may have a brief glimpse at the complexities Eskom has to deal with on a national scale, as they face the same challenges - just in MW and GW instead of kW.
