Hi everyone, Recently moved to a new place. Need a new inverter since we're having frequent powercuts. Currently we have an old inverter that is only able to support first floor (where the bedrooms are located). Noob questions: 1) How good is Luminous? In terms of quality of the product and after sales service. Any other brands I should look at? Btw, I was out of the loop, apparently Su-kam has shut down... 2) I'm looking at this model which is rated for ~4400 watts. I'm used the load calculator at Luminous's site - I assume that this will be sufficient to operate 3 fans + 8 CFL lights + 1 Air-Con + 1 Fridge for 4 hours? The calculator shows I need 6 "200 Ah at C20" batteries. At Rs. 15,000 for each battery, this will become prohibitively expensive. So I'm wondering if I should buy a higher capacity inverter + a couple of batteries (just for lights + fan) and not run the air-con this year. Over the next year we can keep adding batteries, since the model I shortlisted supports upto 6 batteries - does this make sense? 3) The guy who installed our current inverter did not connect it to 'power'. I'm not sure what the correct term is, but basically all large appliances (AC/ Fridge) do not run when the power goes out. Not sure if we should do the same with the new inverter - what do you guys recommend? Thanks for reading.
