About 4 years ago,when we were subjected to the first round of load shedding, I realised that it was only the communication ,entertainment items that I really wanted. I bought a 1500w modified sign wave inverter ,1 95 amp/hour good battery, and some other items such as fuses,, voltmeter ,main isolator switch , constructed this all on a anodised metal baseplate with wheels, an added an extra 12v computer fan for extra cooling. I installed two socket outlets on it for 220v ac, and one for12vdc (maybe a lighting circuit in future.) I ran an extra subcircuit in the house, which the tv and two computers, and the router is plugged into. this subcircuit is connected onto a plug top and onto the mains supply. I have a cheap 12v car battery charger the the inverter. When load shedding occurs, all I do is remove the subcircuit plugtop, and plug it into the inverter socket outlet, I manually switch the inverter on, its really a simple system, but certainly has worked faultlessly when needed. Total cost was about R8000. At the moment would like to maybe add a second battery, which would push up my run time to over 4 hours. Have a gas stove , already, Had ideas to expand my system , but just have not got around to it.
