  1. Then also thanks to @Youda
  2. Thanks a lot for the feedback, gents I already increased Float to 51.5V yesterday to try to get closer to 100% SOC - but I will give Plonkster's values a try now
  3. Yes, for me the Sonoffs simply screwed into the box that was behind the old switch. The pic above is a 1-gang, but 1/2/3-gang are all the same size Just be aware that the Sonoffs require a neutral wire to work, which in SA is not always installed. In my house, my upstairs switches already had a neutral wire in the wall box, but for my downstairs switches I had to pull a new neutral wire through to get the Sonoffs to work. So I would recommend checking what your situation looks like Here pics of old and new 2-gang
  4. This is what they look like installed. They were approx. 1mm shorter in height than my old light switches, so I ended up with a very small gap at the top that I had to patch with silicon
  5. Hi all, I would like to bring up this thread again. I had a Victron MPPT installed yesterday and have moved my panels off the Axpert onto the Victron. My installer has configured the Victron for my Pylontechs - but I am not 100% of his settings. So I am hoping for a bit of help from you guys please On the Axpert, I had the following charge settings (which seemed to work quite well for me): Bulk: 52.2V Float: 52.0V My installer has now programmed the following values: Absorption: 52.0V Float: 51.0V Equalization voltage: 0.00V Re-bulk voltage offset: 0.40V Absorption duration: Fixed Absorption time: 1h 0m Tail current: Disabled Equalization current percentage: 0% Automatic equalization: Disabled Equalization stop mode: Fixed time Equalization duration: 2h 0m Temperature compensation: Disabled Low temperature cut-off: 5 deg Celsius In ICC I can see that the Pylon gets charged to 52V and then hovers for a while around that value (I assume that this is Absorption) - with SOC at 97%. Then it drops to just under 51V and stays around that value (I assume that this is Float) - with SOC at 96%. So I guess my questions are: Are the settings above made by my installer generally correct? Or is there anything that I need to change? What would you recommend I'd use for Absorption and Float? 52.2V/52.0V as I previously had it or 52.0V/51.0V as it is now? What are upsides/downsides and risks of each? Thanks in advance for your help
  6. US model fits for SA I have bought all my Sonoffs from Banggood. With the shipping method 'South Africa Direct Mail (Tax Free)' the shipment has always arrived at my doorstep within 2 weeks (granted my last order was before Corona). And shipping costs were usually even cheaper than domestic shipping from a local supplier in SA
  7. Am running a bunch of T0 light switches all across my house - they work great. And if you order them from Banggood, they are only around $13 or so I really like the Sonoff/Ewelink stuff, so I have a bunch around the house: Outside lights on Sonoff Mini (wired into that light switch) Garage door on Eachen garage door opener Pool pump on Sonoff Basic (only one flashed with Tasmota; my pump only has around 750W, so the Basic is sufficient) Heat pump on Sonoff POW Sonoff LED strip Some other random stuff on Sonoff Basics Unfortunately not all Sonoff products work with IFTTT, but with the T0 and the Basics you can do really neat stuff (e.g. having your lights in the house come on when you get close to home in the eve) The pool pump is controlled via APM based on the ICC data, so switches on/off by itself (and gives option to manually override via VNC)
  8. I have a 60A main breaker and a 5kVA Axpert installed - but only 2.8kW of PV panels. My system was approved by COCT last month. But also would like to install more panels in the long run - so am also interested about trying to find a way to be able to put more than 3.5kW on my roof...
  9. Purchased the Pi and ICC software separately as it is cheaper than buying the bundle (and downloading the ICC image and writing it to SD card I can manage myself)... If you already have a Pi to use, then to me it would be a no-brainer Also purchased the Advanced Power Management software from ICC to control Sonoffs (primarily pool pump) based on ICC data - and works like a charm
  10. Set point temperature (parameter 1 on the panel) According to the manual, this is the optimal temperature setting and results in a 60 degrees outlet temperature
  11. Hi Durran I also have an ITS heat pump. However, I do not fully understand what you mean by the panel being dumb? Mine displays 2 temperatures: (1) at the bottom of my geyser and (2) at the outlet of the heat pump. If (1) drops below 50 degrees, then the heat pump goes on. When (1) has reached 53 degrees, the heat pump switches off again (see more details in the ITS manual available on their website). I have switched off the timer function in the panel (different views exist about that...) I have recently put a Sonoff POW in front of my heat pump as I was simply curios how much power it consuming. Am not using it for switching the heat pump on/off though. Other than switching the heat pump on/off based on the geyser temp (which my panel offers), what other functionality would you be looking for?
  12. My local installer quoted me a Pylontech at 50% higher than what I could source it from reputable local online shops. I was blunt and told him - and we agreed that I would source it and he would install it for me. On the rest of the stuff (panels and installation materials) he was in line or 5-7% higher than what I could find online. So definitely agree with PJJ about the double dipping. However, the difference was not big enough for me to do piecemeal-ordering the stuff from different websites - so I took the lazy way out and just sucked it up... But I also know of other installers (that are very active on the forum here) whose prices are in line with the online shops (but unfortunately not located in my neck of the woods for the installation...). So not every installer does the double dipping
  13. If you are within the City of Cape town, then generally correct - as per page 18 of the following document: Requirements for Small-Scale Embedded Generation.pdf from COCT's webpage Going Solar However, apparently this does not mean directly that your inverter is limited to 3.5kW. I have a 4kW Axpert installed and am certified by COCT - however I only have 3kW of solar panels installed (on which the generation capacity in the letter of certification is based) Applies to both (I am not feeding back to grid)
  14. Yes, it is. I am running that combo I got the link via mail from Manie. I would suggest sending him an email ([email protected])
  15. None of these settings have any impact on the inverter behaviour - they are only for for your dashboard and the savings calculation. You will see that with the exception of PV size, all other settings are under the heading 'Gauge Settings'. These only impact the range of the gauges on your 'Dashboard 2'. For example, the two 'Battery Volt' settings at the top define the range that your battery gauge on Dashboard 2 will display (lower and upper limit of the gauge). The 'Battery Volt' settings at the bottom define which color the gauge will be in (depending on the values that you have set). Again, all of these settings only impact your dashboard - but not the actual inverter settings. These you set under the tab 'Inverter Settings'
