  1. A.k.a Greenskyenergy - definately a scam google showed that www.thewattstor.co.za cached page had an address as below 2 Peddie Rd, Wadeville, Germiston, 1422 Green Sky Energy, 2 Peddie Rd, Wadeville, Germiston, 2000 http://www.greenskyenergy.co.za/ When checking it out on google maps green sky energy pops up as being at this location with lots of comments that it is a scam. https://www.google.com/maps/place/Green+Sky+Energy/@-26.2710863,28.1712433,15z/data=!4m13!1m7!3m6!1s0x1e951a6f8f2f541b:0x360dea8997cf6b81!2s2+Peddie+Rd,+Wadeville,+Germiston,+1422!3b1!
  2. Just a thought, the panels lose efficiency after about 3-5years and drop by around 5-10% anyway, so get panels that wont exceed your VOC, 335w or similar,try to keep each string the same, and add to existing array. Alternatively if you had multiple arrays pointing say east and west, one could use existing panels to carefully oversize an array, position the panels in such a way that enough get direct sunlight say in the morning, the oversized portion getting less light, and it swops around in the afternoon, that way it will give a you a more flat peak on your PV curve, you will generate on
  3. Also check your TP valves (overtemp/overpressure) on both geysers,as I have seen these leak slowly and drop the temp overnight substantially, and consider if you don't have a hot water leak somewhere on one of the hot water pipes. I once had a evacuated tube geyser that failed to heat, via solar or electrically assisted, only to discover that the galvanized pipes had sprung a leak somewhere and the leak was not coming thru the walls or floors? They ended up running new piping to the taps and this sorted the problem. we could only find the issue with all taps closed and hen monitor the wa
  4. Greetings all, Today I went thru to the offices of preston systems as per their website, (Below), to try and make a purchase. New Road Office Park, 5 New Rd, Glen Austin AH, Midrand, 1685 Tel: 011 504 2250 [email protected] www.prestonsystem.co.za However when I arrived and security asked whom i was their to see, they advised that Prestonsystems.co.za appears to be a scam as they are not tenants at th
  5. We implemented 3 systems and have been pleased with the results 1. Backup water Municipal water with 1890l storage, pumped to taps for basins, showers, geyser, kitchen and washing machine, with a bypass option if no power or pump fails. 2. 1000l Grey water temporary storage tank, with pump which runs off PV or mains depending on weather / time of day we run it purely used to irrigate the garden. 3. 2 x 5000l and 2 x 1890 l tanks for rain water, used purely for flushing toilets running off a 3-400watt pump which runs off PV or mains depending on time of day used. Also ha
  6. Folks are also taking the easy option and plugging in these types of globes with battery backup. Not sure how well they work though? https://www.google.co.za/search?source=hp&ei=GiFiX8fRFaO3gwft6bL4CQ&q=light+bulbs+with+backup+battery&oq=light+bulbs+with+back&gs_lcp=CgZwc3ktYWIQARgAMgIIADIGCAAQFhAeMgYIABAWEB4yBggAEBYQHjIGCAAQFhAeMggIABAWEAoQHjIGCAAQFhAeMgYIABAWEB4yBggAEBYQHjIGCAAQFhAeOggIABCxAxCDAToFCAAQsQNQwzVY8V5g9XhoAHAAeACAAecCiAHEK5IBBjItMjAuMZgBAKABAaoBB2d3cy13aXo&sclient=psy-ab#spf=1600266536310
  7. The key thing with geysers is to be sure they cannot overheat and create super-heated steam and then explode. The Two safety's to prevent this are usually the Thermostat (mechanical type cutout) that wont allow the geyser to over heat, and the Pressure / temperature valve on the geyser outlet. With the geyser wise units they also have a mechanical cutout safety on the electronic temp sensor, as well as built inelectronic safety that will stop powering the element if there is no increase in water temp, within 1-2 hours. This prevents a faulty temp sensor / geyser overheat, and also stops
  8. Our dishwasher has two heating cycles of about 10mins each over the 1h56 minute cycle. It then draws around 3kw to heat For around 10mins per heating cycle , and wash. Lg dishwasher. I recently investigated a newer dishwasher and found that our 8 year old one is still pretty close to using around 1.2kwh and around 13 liters per wash. So the expensive dishwashers seem to get that down to around 1kwh and 6-8 liters per wash, so not worth the cost for gautengers, but if in the western cape may consider saving of 5 liters worth the R16k?? The lg automatic washing machine setup favori

    Axpert problem

    Hi Dros, if the panels are in 3S4P configuration you could try to cover the 3rd panel of each string ? Effectively shading it completely. Until your installer could get to you? Not sure how practical this is? Good luck, hopefully the over voltage on the mppt hasn’t caused any damage? alternatively it maybe safer to simply isolate the array from the mppt altogether, to prevent any risk of damage.
  10. There are many models and variants of the AXPERT 5KVA, and as I recently found as well that models I had were not compatible with the newer versions on the market. I ended up having to buy three new units The communications cables were the same as far as the eye could see between the old and new versions. What makes and models of the axperts do you have ? check the nameplate on the side for the specs? Also both / all inverters must share the same battery bank. Also older units had a power factor of 0.9 and the newer ones I understand are now a power factor of 1.0 which can be one o
  11. Good Evening Arandoza

    Can you kindly inform me if the two RCT Axperts are still available as per powerforum classifieds

    I am also interested in the JA 275W solar panels

    Please PM for futher action to be taken

    Thanking you


  12. Also curious if they work with the Axpert’s?
  13. What application would one use with an axpert inverter to read the inverter values and post them? Do you have an app to do this yet?
  14. I am running 2.88 version from centurion solar, and all is ok. It included Emoncms on the pi, and could be setup to feed both a local and cloud instance of emoncms. If you have a look on the centurion solar and then on the iccsoftware websites one almost gets the impression there was a falling out? If I recall correctly the ICC site talks about advanced reporting only being supported if you buy a specific version of the pi version including the pi and hardware from ICC? And the version numbers of the software are 2.9x, where as the centurion solar ICC software just states there are no fur
