What do you think about this?
An invertor mounted close to the DB which is connected to the lighting circuits only, with a relay coil energised by the mains power. The invertor and batteries could be mounted in the roof above the DB and the lighting circuits run up into a control box. The LED lights could all be 230 volt so that there are no issues with volt drop etc.
A relay mounted in the DB or in the control box above the DB with the NC contacts used connect to the inverter supply and the NO contacts for the mains supply.
When there is a power failure or load shedding the relay will switch off but the lights will stay on, powered by the inverter.
When the power is switched back on again the relay will energise and lights will be fed from the mains supply.
A stand alone inverter next to the TV for the home entertainment centre and a spare plug for charging stuff etc.
Gas stove, for cooking, heating ,etc.
What more do you need.
Running a generator is no cost effective and is noisy, beside what more do you need.
By the way a 2 plate gas stove with a 9 kg bottle cost a couple hundred rand and no COC is required, you dont need a R10 000 gas stove with copper piping, COC and oven just to get you thru load shedding.
Let hear what all the bright sparks have to say about the relay (used as an ATS) in the DB with the inverter.
