  1. That calculation Z-R is the real value. Other added extras are benefits that can’t be measured by Rands. Solar is far from perfect, but it beats the load shedding!
  2. Same here, on a good day I still draw 0.5kWh from my prepaid meter, and in the afternoon the excess solar has nowhere to go. I started using fans and portable aircon just because I can, and I guess in winter I can use an electric heater instead of gas. it’s not perfect and payback is very very long but to me the effort is worth it. No load shedding troubles, replacing gate motor and garage motor batteries, less paid to our dear municipalities, reduced carbon footprint and increasing the value of your property.
  3. Hi Bobster, Achmat’s estimation is pretty accurate way of calculating the long term returns. He has enough data to look over a longer period of time. I would optimistically take total amount of solar panels and multiply that by 4.5 hours. That would be rough estimate of what solar can produce on average. In your case you should average around 560kWh per month. That is already more than you consume but losses on battery charging plus solar variation will set you back a bit. My panels on a sunny day charge the battery from 30% to 100% before 11:00 and on a cloudy days like today I
  4. Did you manage to find a correct setting for your tesla? Maybe share some settings screens for us?
  5. Just proving my point. Your CoCT balance is R741.93 +service charge of R12.36*30 (R370.80) -R1116.08 = -R3.35 You would have been better of going off grid with batteries. Lets look at CoCT - they scored 1120.48KWh from you, basically leaving you with zero account, and sold that at R1.83 or more to your next door neighbor. Happy bunch! Not to mention that they will cap you off after 12 months of you becoming net exporter. If they don't, I'm happy for you. On average, you produce about 50KWh surplus on top of what you use during the day, and consume about 13.5KWh at night. Yo
  6. I agree that battery ROI is not very good, but for some people it is a necessity (small children, people with medical needs etc.) and for some it's a comfort. The person starting this post already has a Tesla battery and only question is to not get charged for feeding back. I am certain they did their calculations, work out their payback and made a financial decision based on that. But my point still stands that conditions between Eskom or municipality and SSEG are unfavorable and will actually get worse. You are currently paying at 2.5 times the price the energy you sold them the sa
  7. This is the point I was trying to make. The conditions are not favorable for SSEG anywhere in South Africa. I am in Ekurhuleni, and if I want to feed back, I have to pay for the change of meter and get ZERO for feeding back. Best option, as per Achmat, zero feedback and store excess energy in batteries. Considering load shedding, unreliable supply, municipal account complications and all those factors, we cannot think outside of the box.
  8. Hi Erastus, I assume your last column is 2 months behind due to them having to calculate and give you credit? My worry is that in the info sheet attached they state that you have to be a net customer over a 12 month period, and by October 2021 you will be well into an exporter. Does anyone have experience with this over longer period of time? What happens to the negative amount? Deducted from your total municipal account? PV info sheet on tariffs_final.pdf
  9. Agreed, so you have to pay 12K for the meter, pay monthly cost of R12.36/day and still be a net consumer of electricity. I would think that even after you have paid for the battery, which caters for ever so present load shedding situation, i would spend that 12k on more panels or more batteries in order to get closer to being off-grid.
  10. You just need to break Live wire that is supplying your pool. This can be done with Sonoff, Shelly 1PM, or contactor as other members suggested.
  11. Hi Bobby, only your top battery run light is on, other’s are off. everything else seems normal. is your baud rate set to 500 on can bud? does your GX device not show batteries at all?
  12. Maybe the best to let municipal electricians check it out.
  13. Hi Bobster, clapm meter on each property will give you a good indication.
  14. Lower voltage means higher current and this could damage your appliances. Anything with induction motor will struggle, although newer appliances are built to manage these kind of dips. i would for safety reason try to avoid switching on the inverter unless the incoming voltage is around 200v (+/- 10%).
