    I will parallel the breakers at the inverter side ( bottom part of breaker) So the cables between the 2 breakers will be a busbar replacement. Pink

    Is there any reason for not parallel my 2 batteries by just parallel them at the battery breaker with wires between the breakers? Pink

    How they know whats used at the different rates? In my place they just read of the analog meter once a month how many units consumed (If i not misunderstood something) Pink.

    Growatt used to be max 18A but later upgraded to 21A with new firmware. Pink

    V limit 450VDC. So v limit will get you around max 10 panels if all in one string. 2 string in parallel you can have 16 panels. Pink

    If you able to connect 2 strings in parallel the voltage is half compared to all panels in serial. Growatt now handle 21A. V limit 450VDC. So v limit will get you around max 10 panels if all in one string. 2 string in parallel you can have 16 panels. Pink

    Growatt SPF500ES now support 21A, who is perfect for most 330-350 watt panels with around 10A Current. That way you can set up for example 7+7 or 8+8 panels with parallel connector and then a more medium voltage level. In this example you get around 20 Amp and 400v and 5k watt panels. Then parallel inverters up to needed capacity. Edit: Its smart not push the V limit.. Pink

    I got mine 330w panels for 2990. but the price was in the store only. Pink

    Much interesting info here.. I had to think over my plan as a last opportunity before adding my panels to roofing. So plan is 7s2p on each side. each side to its own Inverter. i have 12 degree North and 192 degree south. My roof angles about 15 degree. Plan is panels on the outer part of garage because of longer sun time. In afternoon house give some shadow on the part of roof nearest hose. Should I consider all panels on South side??

    My planed diy 2 x 13kwh will cost 140k Pink

    You can get very nice deals on 340w now, check out for example Global House. Pink

    12mm x 180 cm ground rod for surge proctor is ok size? There is maybe a 16mm version too.. and length 240cm. Pink

    How you apply the Uni-Seal jointing? Cotton stick? Pink
  15. Pink7
    Main idea was sanding then cleaning then Uni-Seal jointing compound and then assemble. Pink
  16. Pink7
    Use fine sandpaper ( 400)? A quick rub over with emery, can you explain? Cleaning busbars. terminals etc with alcohol? Pink

    Thanks for the info Crossy, there been lots of issues with Growatt spf5000es with Neutral ground bonding ao i guess i dont dare go that route. ( Most on US version as i understand) Pink
  18. Pink7
    I has start thinking about doing same. Do you have same ground for inverters and surge arresters or they are separate grounds? Pink
  19. Pink7
    I remember a active member here on the forum had grid ground hit his MPPsolar inverters.. so i would be positive for a plan who not include grid earth/ground. I have a hope to run my setup more or less offgrid. Can you explain TT "island" with a local earth rod? I need to ground 4 ports from inverters inn/out AC ports, and 4 Surge Protectors. Pink
  20. Pink7
    My inverters is placed near my main breaker box. I will use a new local earth for my 4 x Surge Protectors. Pink
  21. Pink7
    So my grid ground cable is connected to my breaker box who goes to home main ground. I have 2 inverters with acc in/out each with ground ( so 4 ground port in all). Could i just connect all those 4 ground together and to my main ground cable? Pink
  22. Pink7
    With grid in to inverter turned off on breaker you still connected to grid ground/earth? Pink
  23. Pink7
    I want gloves who protect my hands to electric current, and who also protect battery poles, bars etc from marks and dirt etc. Any of you used gloves on this type jobs? What gloves to get? Pink
  24. Pink7
    Smart that you have grid opportunity on inverters and jus enable it when needed. Pink
  25. Pink7
    Thats nice that you able to reduce PEA to near zero. I want to try run my Growatt inverters without grid connect for less chance for any issues so i try double check my plans before next step. My plan is 9.5 kw panels and 26kw (2 x280A 48v) battery. We currently use 20-25kw per day from PEA. How this will ad up ..or not with different weather types i dont have much idea on..Time will show.
