saflyfish Posted February 5, 2020 Share Posted February 5, 2020 Ive been looking at the two options.The quietest genny you can get for the power i need is the honda eu65is inverter gen at R60k.Its a 6.5kva unit with 5500W.Im in a complex so cant have a noisy gen.Ive phoned a few inverter supply companies and they reckon about R40k for a similar inverter unit with batteries.I need to run the following:1 x 12000 btu split unit aircon,non inverter (new ac)10 x overhead energy saving bulbs at 14w each,not led2 laptops and chargersFibre line,fibre router so we can work on laptops and have internet2 x 32" full hd led tvs and two dstv decodersPrice aside when we run into stages 3 to 8 the gap between sheds can be as short as 2 hrs.I believe the batteries take 6-8 hrs to fully charge.So im undecided as both have advantages and disadvantages.Any advice,suggestions greatly appreciated.

Richard Mackay Posted February 5, 2020 Share Posted February 5, 2020 Can you do without your aircon and watch TV on your laptop during power outages? If so you'll be able to do this for less than half of what you were quoted... Quote Link to comment Share on other sites More sharing options...
saflyfish Posted February 5, 2020 Author Share Posted February 5, 2020 Unfortunately not the aircon is non negotiable for the 2 hr load shedding Quote Link to comment Share on other sites More sharing options...

The inverter just sounds better and cleaner than a generator, The aircon is going to pull about 8Amp and you will need those batteries to be up to the task. Might be worth spending that extra R20k on extra batteries with the inverter. Quote Link to comment Share on other sites More sharing options...
JustinS Posted February 5, 2020 Share Posted February 5, 2020 Looking at your list, that is probably just over 2kW draw. Which is 4kWh for a 2 hour load shed. I got some quotes from Solar Man in Pretoria for around R50k for a similar setup (2x3kWh Shubart batteries + 1x 5kW Axpert inverter). Should be able to comfortably recharge in 2 hours.

You might only be able to draw 50% out of those batteries. Quote Link to comment Share on other sites More sharing options...
