  1. The only way to get that is to have loads that draw the full power from the panels. The panels will never produce more than they are asked for from the loads/inverter/battery.
  2. Yeah I always simply use Ctrl/PrintScreen, then Ctrl/v works like a charm from any pc with windows or linux. Well on this forum anyway
  3. here is the original from the posted excel sheet that @Antonio de Sa posted
  4. are you trying to match 3 smaller panels ( the parallel ones ) to the 4 other panels in series? Effectively giving 5 panels in series. if yes then that would be correct.
  5. if your solar is sufficient then it will hardly ever use grid anyway But definitely do not put it higher than 50A
  6. lithium batteries perform best at 0.2C so your 50amps / 2 = 25amps to each battery is optimal already and should not really be changed It wont kill the batteries going higher, but they will sure last longer keeping it the way it is. And as @Nexuss said too, if it's been happy all this time then don't mess with it
  7. I have not seen the ecco range for sale in SA yet. They basically fit the normal 8k into the 5k chassis, and the 5k into the 3k chassis. Mostly a cost saving, so some of the "not so important" hardware is specced lower or omitted.
  8. That would be solaredge But they are quite expensive systems
  9. I dare suggest that is not limited to the solar game...
  10. I have been saying that for ages now Standby ( UPS ) Systems Will No Longer Be Allowed. ( their fancy info-graphics are not so disguised scare tactics ) They are e...ing insane, but I do understand why they are having this knee-jerk reaction ( nothing to do with safety as so many keep defending them on ) The rapid rollout of solar by all their normally good paying customers is threatening their revenue streams and they are sh$ng themselves as to where they going to find the funds to subsidise the non-paying users. So for them simple - regulate the crap out of it to slow down the uptake, as least for as long as no-one challenges them on their rules. IMHO - for UPS style non-grid-tied/interactive then as long as my/your installation is safe and electrically compliant ( valid CoC ) then their suggested rules seem to be a bit much of an over-reach.
  11. That trickle feed is quite important, the inverter is not quick enough to prevent power going back to the grid when loads switch off, that trickle feed helps mitigate that back-feed a bit. I have found 50watts to be a sweet spot on my setup.
  12. The CT coils MUST/SHOULD be at your incoming live just after your municipal/eskom meter before anything else. This is usually at the entry point of your main db. Also on the images of the screen you post it is not showing your home grid at all? The 5k units have a small internal fan, that only comes when the caps get a bit warm, that fan boosts some cooling over the capacitor bank. If your cover is on you should hardly hear that fan,
  13. Correct, and part of that being an "expert" is that they should be taking the time to explain the install to the customer, especially all safety aspects. That layman who is clueless needs to be given at least the basics of safety for their system, anything less would be irresponsible. Many installers do the install and then are gone onto the next install, leaving the poor client clueless on what to do if there should ever be some sort of fault or emergency.
  14. Agreed. I myself would like as much info as possible before dropping 10's of thousands into equipment. But then again some people buy cars without even test driving them.
  15. If that big chimney shadow misses the roof then I would put all on that north/east side. but afternoon production may be on the lower side, which does not matter too much if the batteries are not being used too much in the afternoon. Maybe aim for more panels and add those extra to the west side to compensate/boost the afternoon production. Those panels are VMPP: 34.9 V and Voc 41.3 V so 10 in series on one mppt maybe just on the safe side and depending on the inverter? may have some clipping of the current produced. Those panels are about 17amps.
  16. Go to the warehouse and see if they legit The JASolar panels 550watt on their site are selling below cost, so unless those fell off the back of a truck somewhere or they importing directly themselves then I would be very hesitant to give them any money. The site is currently about solar, but the FAQ's are talking about custom PC rigs, which may indicate they previously "sold" crypto rigs. Maybe they legit and simply pivoted from crypto to solar
  17. Crazy but possible considering the massive dumping of cheap Chinese inverters and batteries coming into SA at the moment. There is a big market for budget systems. Then of course there are also the many scam offers that are catching all the desperate load-shedding-weary people out there. You have to wonder sometimes, on this ad for example, legit or not - AC box with MANUAL and AUTO changeover
  18. What power amps is the turbine producing and pushing into the battery and is it constant enough to charge the battery to full? Wind turbines do not usually produce a constant flow of power so it may be that the battery is not getting properly charged up? Do you have loads on the battery? Do you have solar to help with the charging or are you relying only on the wind turbine for charging?
  19. with all the rain in cpt these last few weeks I will have loads of power
  20. For safety of your equipment do not go past the MPPT Range(V) of 425V anything above that risks potential damage. The ideal voltage for maximum performance is 370V that's the point where the MPPTS work at their best.
  21. If the installers are buying retail and then adding a markup then they are simply not reputable installers. Reputable installers should have trade/supplier/installer accounts so once they add their markups they should come in about the same as retail ( some even below retail ) on their parts list. If they are coming in above retail then find a new installer to quote you My Opinion
  22. With the sunsynk/deye inverters you must always have the CT installed ( Correctly at your incoming eskom/utility live line before other circuits ) to ensure everything works correctly.
  23. On the solis s6pro you can connect the microinverters to the aux/gen or to essential loads output then the inverter controls and pushes power where it needs to go. Something I do not think the sunsynk can do.
  24. you should get roughly 25 kWh AC per day in ideal conditions good days could be more, bad days could be less. Provided of course that your batteries and loads have sufficient draw on the panels.
