    • Off-Grid Trial For August/September 2022
      With all the confusing talk of new eskom tariffs with R900pm fixed fee from next year, my wife and I have decided to trial going fully off-grid for the month of august using our modestly sized DIY solar system.
      For the next 6 days till the start of August I will be doing some trial test runs just to fine tune timings of everything.

      For starters I am running Loadshedding from 9am till 9pm.
      My crypto mining rigs will now only run from 9am till 3pm everyday to give the batteries a fighting chance

    • Earth leakage not working when mains down
      Hallo Gents,

      Can someone enlighten me on this issue, I have a plug tester showing correct plug wiring and correct earthing. When there is power 3 lights are on and all good. But when there is load shedding or I turn off my main feed the earth leakage light goes out. I do this test on a plug that is coming from a solar inverter that is wired into the db’s earth and neutral and live going through a cb. 
       

      Where do I start looking?

      Thanks!

    • Evening,

      Has anyone purchased items from the power forum store? I am struggling to see if items are in stock or not. Would like to know before making payment (60K).

      Have tried calling and emailing. No response.

    • Hallo,

      As so many previous threads, I need your advice.

      My elect bill is about R4k per month, I need to reduce that and minimize loadshedding.

      I only have R65k to do this. I will DIY what I can but need advice.

      I was thinking a Sunsynk 5KW inverter and a small battery for starters. Something like this:

      https://powerforum-store.co.za/collections/batterys/products/pylon-us2000b-plus-2-4kwh-li-ion-battery-excl-brackets

      Budget is now at around R38k.

      Is it possible to add panels and get all the cables/mounting/DB board/sundries?

      My idea is to run most of my load during the day, when we have sufficient sun and only to use the battery during loadshedding (running only essentials). During night/cloudy days, I will use grid/Eskom. 

      I am hoping that the above would save me about R1500 per month on my bill? If it saves me R1500 on the bill, I can spend the money.

       

      I have the following:

      - 2x 200litre electrical geysers

      - 1x Stove

      - 1x 750kw swimming pool

      - 2x Front loader washing machines

      - 1x Dishwasher

      - 1x 1.1kw borehole

      - 1x Electric fence

      - 4x fridges

      Only using LED lighting and I do not have any power monitoring. I take a picture of the electricity meter daily at 06h00 and I see the most I have used during a day is 45 units. The least is around 17 units. We do not use the stove/oven since we have a airfryer and a deepfryer. I know I need to reduce my daily consumption but spending R7k for a gas geyser (times two), leaves me with R51k. Adding electricity monitoring, reduces my budget even more. 

      What do you suggest?

    • hello, sorry for the translation but I'm Italian. I expose you my problem, I have a 3200w 24 volt inverter I noticed that the battery Zavoltage reading is wrong. When I am taking 1kw the difference in reading with the tester also reaches 2v. Is there any advice or any component to replace? thanks to all cordial greetings
