Due to on going load shedding, I would like to run my 220v house lights on 12v using two 105ah batteries and inverter. The batteries would be permanently charged by a 220v charger. The total power for the house lights is 175w ,obviously they will never be all on at the same time and luckily I do have a spare small 350w inverter. 

Is the above possible ? Anyone with similar setup?

Sounds like a good idea.

Alterations would entail isolating the lights from the 220 volt mains at the DB and connecting to the inverter.

Suggest using a qualified electrician to do the alterations.

I have used this set up for the past 4 years without any problems. You will need to do a bit of ceiling crawling but it is worth the effort. You can split the LED modules as required but I use 3 modules  in big areas and single modules in bathrooms etc just connect the modules to a piece of wire and see how much light you get and place them accordingly before you mount them permanently.I make a small hole in the ceiling cornice just big enough to push the wire through and glue the LED modules to the ceiling and solder the wires . I place a pull switch in a central area and connect all the lights up . In all I have 12 LED modules R15 per module , 2x 7Ah alarm batteries R230 per battery , a 10A solar charger R280 and a 30W solar panel about R300 , total cost with wire , pull switch and fuse about R1600 . This set up has run for 4 years and used amost every day without a hitch , no fiddeling in th DB , no sparky needed , just remeber to use the correct fuse according to how many modules you use and solder all the joins and insulate with heat shrink for good insulation.

I have also installed 19 small 12V LED's throughout my house. They are controlled/powered by a 7,2Ah battery and this was done 3 years ago. I am considering to maybe add a solar panel and controller for the charge of the batteries. This setup is also not tapped into my DB board and runs completely separate.

Great idea , and also cost effective as well.A small clarity, where re is your solar panel mounted? Roof or inside the window? How many watts are those lights?

The LED wattage varies with an average of 1.5w per module , I have a tiled roof so I just pushed the wire through a gap between the tiles and glued the panel onto the roof tiles with no more nails , I didn`t get too technical with positioning just where I thought it would get the most sunlight.

The madam reminded me that I have a stash of Lumeno 6LED strip lights in the house,I want to mount these on the doorframe above the door , then run cable through cornice. These are only using 0,12A per hour which very very economical. I have attached photos, (it’s  still untidy). What are your thoughts on mounting it on the door frame instead of ceilings?

Hope my engels come right through it is possible but say their is for two or three days no electricity how will you load your batteries again maybe for a back up think about the sun as n power resource (sun panels) sterkte 

One could have planned for days or weeks without power 13 years ago and the event did not come. In over 22 years where I live we had only one long power failure - not load shedding and we were without power for 36 hours. All other times of no power was only for may be up to 6 hours at a time. Really no train smash as all of us have camping lights and can braai or use the gas stove.

At least Rare Breed did get good answers and yes if you don't need 220V to charge laptops or phones the 12V option with LED strips or lights is the cheaper option.

I run an inverter with 100Ah batteries and have my plugs and lights on it via a transfer switch. Although all plugs have power we make sure not to switch not needed things on during the load shedding period but use the normal lights which are all LED or CFL. If phones need to be charged I use USB sockets on my battery box at times like during the day. We cut hay while the sun is shining and panels are giving us some power even if it is raining. About 3 times I charged my batteries at night from my m-bike for a few minutes for each battery during the rainy spell in Feb.
