  1. well then it is still retarded, both fukushima and chernobyl was due to GROSS human negligence or error, and neither of them the actual fallout was nearly as bad as what the press or stories makes it out to be, yes nucluar fallout is not what you want.... i am not ignorant to that... just making the point that people who little to nothing of nuclear speak about it like they are experts on the subject which is quite annoying.... evedently the nucluar waste generated by the pebble bed reactors would have been so little that all waste generated during its operational time could have been stored o
  2. great point or idea bobster, having worked on the old Pukke or north west PBMR project on their micro model simulation project while finishing my studies, i can vouch that nuclear is by far the cleanest and safest form of energy generation (or atleast was when we did the research now more than ten years ago... i doubt it has changed much), but most of the tree huggers have NO sense or idea of how these plants actually work, and the technology behind it... actually neither how the normal coal or gas fired plants work either, so why comment on something you have no idea on... i think if memory
  3. Does your system trip while eskom is present....? Almost sounds that way when you describe it... it is def not supposed to do that.... i have the same inverter.... did not split my backup and essential loads... not in the traditional sense, i have the entire db loaded on the main supply side of the inverter, and the backup as well, switching with a manual changeover, i have never had the inverter reset or trip when used on the back up side if the grid is off, you can on the one had easily do it, but also if doing things responsibly it can actually be quite hard ( i am in similar setup to yours
  4. i am pretty sure if you build a proper support structure to install the panels onto, and just pop rivet the panels frames to each other with some sillicone inbetween you will have zero leaks. sillicone makes for a pretty strong bond and waterproof bond, and will take on the exact profile obviously. I would just look at perhaps getting a better type that is maybe UV stabilized. Also maybe during the design put some spacing here and there between strings, should you need to clean, or do some sort of maintenance... although you should be able to get access from below....
  5. yeah man, i hear you, product is ultimately only as good as its support... think this is were sunsybc is going to hurt the goodwe brand.... just on a side note.... you did follow the thread about the nuetral and how it should be connected on the goodwe, was a issue, on my installation, before the chinese guy rocked up....
  6. @gbyleveldt sorry to hear about your issues, i bought four goodwe inverters, two em, and two es models, the two es worked perfect from the word get go, so did the one em, the other one was a disaster from the start. I did all 4 installations myself, not rocket science to be honest, although as soon as i had issues with the one it was a issue that i did the install myself, eventhough i am way better qualified than most installers probably with all due respect.... anyway, long story short, struggled for weeks with segen, it was a nightmare, their service is [email protected], excuse the french, no other way t
  7. Hi Paul, THa is very interesting, i am also using a goodwe, also the 5048es at my home installation, and have a axpert or votronic at my office.... imo the goodwe was light years ahead of the voltronic.... but i was recently wondering how the sunsync would compare since the similar pricing and the units on paper does look impressive.... that is good news to have another option.... @gbyleveldt i have been using my goodwe with 5 x 4.8kw lithuiom batteries not supported by the inverter firmware for almost two years no with no problems... without the bms functionality or co
  8. hi man, i made myself custom mounting frames from angle iron, due to shortage of material at the time of installation, but also because i wasn't crazy about the existing designs. I stay in the vaal, vanderbijlpark, and we get ridicilious winds here from time to time, twice a summer there is storm like wind pulling out trees... so i was weary of panels blowing off. I have a tile roof, at 12 degrees i made a simple flat iron adjustable connecttion at the back, so you just remove two screws and adjust it to a second or different setting and insert the screw again... and boom diffferent angle for
  9. hi, I was pumping about 2.7kw into my batteries, rest went into my house load.... snapshots i took wasn't the best ever,i have to admit i was a little excited when i saw it, was for around 25 mins at around 7kw... will check my VOC, i have the canadian solar panels.... however my dc voltages are close to the maximum upper limits... but system is pumping like a beast though so seem to be happy... did 40kw last week sometime, adjusted my panel angles a few weeks ago, so reckon i will be able to get another one or two kw extra in december during a clear day..... rest of the days production
  10. i have to agree with @fixamess, the goodwe is really a carefree inverter for the novice user, making for an easy installation.... and it is very efficient and can handle quite some nasty loads without problems.... you can oversize quite a bit... i have 22 x 330watt panels installed, totalling a theoretical value of 7260watt... and i constantly get around 5900-6200watt during peak producition which goes or equates to between 80-85% efficiency... during the week i actually had the inverter hit over 7000watt producing stable for over 20mins... this week has had lots of cloud cover so i am sure th
  11. Hi Plonkster, I am still a little confused, so will the inverter work better at 500 v oc rather than at 550v? I have 22 candian solar 330watt panels currently setup in two strings of 11 panels each, giving a theoretical value of 501.6v (v oc is 45..6 @ STC, or 41.9 @ NOCT), i have another two panels already mounted, as well as cables in place and everything, but i never connected them because i thought it might cause problems, since my losses was less than what i expected from theoretical values.... so if i understood correctly, my v oc on the panels will be 547.2v oc if i add the
  12. hi guys, Not to derail the original thread or question, but it actually made me think of something i saw the other day, but perhaps @FixAMess or @Fuenkli or @Jaco de Jongh or @plonkster or @Chris Hobsoncan just clarify something, obviously you need to pair the strings according to max rated wattage etc, as well as the max amps rated for the inverter, when considering the volts though, in the goodwe manual it says the mppt voltage range is from 125-550 volt, then it also says that startup voltage is 150v, and then finally it mentions that the MPPT voltage range for full load is 215
  13. so out of interest, i reinstalled and changed all the piping to the sans alternative installation over the weekend... works 100% without changing any of the hardware... still not sure why the supplier would give an installation option that does not work... happy it is sorted however... thanx to everyone who exchanged ideas and took the time to comment and help problem solve.... thanx guys.... had a few hot solar showers this week... works perfect now....
  14. to all the guys who replied, thanx a lot, as far as i can tell, i have everything connected correctly though, pump pumping in the correct direction, no non return valve facing or installed in the wrong direction etc etc. The flapper type non return valves i selected because they have way less resistance then or when compared to the spring loaded counterpart, and can be opened blowing into them very easily, so i am sure that is not the problem, which also led me to thinh the head might be the problem, but surely the pump must be able to pump against some head, my pipe work is not that far to th
  15. sorry, i worded my explaination on the vacuum breakers wrong... last section i meant when needed it will allow air into geyser... not let it escape... that is my humble understanding... again by no strecth am i a plumber... or have a lot of plumbing experience... just how i seemed to me when i tried figuring it out when installing the solar geyser.... obviously there is more to it than what i thought... must be missing something stupid here....
