  1. 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....
  2. The vacuum breakers as far as i know, the ones situated at the inlet and outlet of the geyser is only there to prevent the geyser to collapse due to full vacuum and geyser unable to draw air in this event... these work basically like an inverted non return valve as far as i know... if there is water it will push the valve or breaker closed, if it needs air the valve will open to allow air to escape... regarding the air release valve installed at the highest point... i even manually opened this one to let out air until it was only water flwoing out but still no joy... i am also of the opinion there is no flow... maybe some trapped air... but since there is no leaks anywere visible... and i opened all taps for air to release until it is only water i cannot understand why it is not working... and 2 installations... neither is working.... ^&*()_ i am normally quite patient, but have tried everything, and i am 1.98 meters tall, my roof is not exactly a user friendly enviroment for me to work and spend time! oh the joys.....
  3. hi Guys, Thanx for the replies so far... that is what i can understand @Fuenkli... i can hear the pump is running... i tested with multimeter voltage is 16volt (dc solar powered pump) but i can even hear it is pumping.... i disconnected the valve, took it out and tested it, working 100%.... I had or did install an air release valve... at highest point.... i also reckoned no flow... but %^&*( why... pump is installed at same level as base of geyser so should have sufficeint water feed.....??? Oh an i used method one... should maybe try method two.... is about ready to load the whole setup onto my bakkie and dump it at the local trash heap....
  4. Hi Fuenkli.... sorry makes sense... i followed these instructions below... first updating and ensuring my exising installation was corrected if not according to standard or sabs installation standards... although again for the record i am no plumber, although looking at kwikot diagrams my existing geyser had one or two smaller installation errors i first corrected before installing the evt geyser as per installation instruction... only thing i did differently was installing an additional non return valve (flapper type) after pump, but thought this should be better and actually help.... have a look and fire away... i will appreciate any advise or things i can check since i am frustrated crazy and at my wits end with this installation.... as mentioned i think it is a flow issue, when i open i warm water tap or shower while pump is running during the day there is sometimes excessive noise, maybe pump cavitating... but why can't it feed enough water from geyser... pump inlet and outlet is 15mm i used 22mm coper pipe to connect with reducer to ensure enough water is fed... this thing drives me mental....

  5. Hi Guys, Is there no plumbers or people with plumbing experience on here... finally received a drawing or directions from the sun pays, follow it to the letter, everything installed but the setup is not working. I suspect i am not getting enough or any flow... not sure what the cause can be... i hear the pump "working", took it out and tested it pumping water from a bucket, but then it is obviously not pumping against a head... the temp in the solar collector reaches 104 degrees minutes after the sun rises and never drops, telling me there is not or little water in... wtf is the problem... i am so annoyed with the system by now... and the sun pays seems not interested or unable to guide me to find the error... anyone please..... thanx in advance...

    hi Paul, Quite the novice myself, however i will try and answer the things i think i am fairly sure about... i have a similar setup.... one problem you are facing during general mode is because it seems or sounds like you are not grid limiting, and is indeed feeding back into the grid, that way it will not charge the batteries first (in essence you are using the grid as a battery transferring extra generated power back to the grid). You need to limit you exporting wattage via the pv master app to 0 watt. That way any extra power not used by your instantaneous load will be charging your batteries, now it goes into the grid, change this setting and any etra power will go straight to your batteries the moment your pv start generating,(grid backfeeding is also depending on where you are actually illegal, except for capetown and i think PE last time i checked). Luckily with the goodwe it is not dangerous since it will isolate itself if the grid goes off preventing an accidental electrocution of a guy working on the municipal lines.... in theory... If you fix those settings you will find the general mode works great. I have a similar setup to yours and regularly or daily charge my batteries at a rate around 3000-4000watt or there about.... you can go to a maximum of 100 amps charging current granted your batteries can handle that charging rate.... for the mppt's, that is the dc rated voltage per mppt string, so you can safely add the additional panels on the second string, should be no problem, you can add even slightly more since you are still under the theoritical maximum and there will be additional losses due to cables and panel angles etc etc.... hope this helps or makes some sense...
  7. @plonkster any ideas guys.... how do i find the fault... i checked all the globes as suggested although as i mentioned this should not be the issue since several rooms are out, and a blown light bulb surely won't cause several rooms not to work, surely the lights are all connected in parallel etc... i checked the breaker and it works, meaning i can measure current going through it when on... and none when off... i opened all the switches and checked connections... checked light fittings as well... all seems ok (repaired two dodgy looking connections, but still no joy)... how or where do i start to get the fault... no electricians available this side for the foreseeable future due to covid.... any advice anyone.... sorry to tag you plonkster but you do seems to know about anything or everything electrical....
  8. Hi man, Sorry i should have mentioned, mixture. The hall or passage have led lights in, in most rooms it is energy saver screw in lights... 11 or 14watt warm white globes....
  9. Hi Guys, So hoping there is someone knowledgeable who can perhaps assist.... so i was working on my solar geysers and alarm setup during the lockdown... just as background story / information... since two nights ago my lights are just going crazy... every night around 18h30-19h00 if i switch on my passage or bathroom or dining room lights or some of the rooms lights (seems totally random in terms of which light triggers the F-up) and then the after a while, sometimes almost immediately it start to flicker, goes weaker in intensity and then completely off... circuit breaker does not trip when this happens, and the lights won't switch on again until the next day or night.... i manually switched off the breaker everytime this happens for safety, or seems of feels safer to me, next morning it works again. FML... what could this be, how do i find the issue... i have two light circuit breakers, only one circuit is affected (both 10amps each), but means half the house, or about 6 different rooms and the passage, super annoying.... since the light and trigger all seems random i don't even know where to start fault finding... except perhaps starting with an exorcism... ffs... i have single phase power... any help will be appreciated... (i am no electrician but know my ways around the basics and have a proper multimeter to test etc) i need to have some sort of guideline what to do though.... Any advice at this stage will be appreciated... no other light or plug circuits seems to be affected except all the lights connected to this particular circuit breaker, can's see or smell anything burnt or damaged during work but i guess it is possible....
  10. hi guys, So to all the experts out there, bought a heat tech hp geyser, and a 18 tube evt solar geyser from sun pays. Can anyone supply a diagram on the piping, on how everything should be piped for the system to work properly, where what valves etc should be... i have no plumbing experience, but is handy enough to install the piping if someone can hopefully guide me as to where what should go ideally. I have the geyser as well as the EVT already installed, i just need to do the pipework...? thanx in advance guys...
  11. Hi @coulomb thanx for the reply, i will try it and see what happens, mine is not switching correctly, i will try changing the setting and see if it helps... also thought it cannot be correct, makes not sense since it will basically not help if it basically simulated a trip everytime before changing over.... will see and check, unit supposed to be brand new.... thanx again....
  12. Hi guys, thanx so much for all the feedback and advise. I changed the settings as recommended, and the inverter is now working, the way i thought it would and should, just one more issue left, if and when it switches between the utility or eskom or grid power and powering from the solar or batteries, the moment the load is too big and it needs to switch, the switch is not smooth, meaning the power goes off, almost like a breaker trip for a few seconds, and then power returns, i thought the transition should and would be smooth... is this normal... can anyone comment....? Just seems odd, and can def not be good for anything electrical connected to have a few trips a day because it switches between the sources @Coulomb @Chris Hobson @plonkstercan you guys perhaps comment if this is normal behavior for this inverter, and if not, what can cause this....?
  13. @Coulomb Hi coulomb... thanx for the reply... will read through it and see if i can understand everything.... i really hope the batteries aren't stolen, it was bought at a reputable business mentioned earlier, not off the back off a pickup, that being said, after the carte blanche episode i did have a look, and the specs seems different when compared to the leoach, similar on some things, but these seem more powerful, but then again both are lithium so i guess they should be similar in essence, and the batteries physically also looks completely different, is possible that the enclosures was just changed i guess.... anyway, again i do appreciate all the input, i will try and change all the settings and see how we go! Model number of the mecer inverter is SOL-I-AX-5P64... thanx so much... appreciate you taking the time man....
  14. @Coulomb can you please comment on my intended settings in post above... and whether my wiring setup is correct... on the settings portion especially the settings highlighted in red i am not sure how and why to select what.... thanx a lot man....
