    Cycling batteries when not in use?

    I think you need to leave the Axpert on but you can switch off mains breaker between the Axpert and the load. Regards Mark

  6. Was admiring this piece of blue kit today and spotted something interesting (a worry actually) in the video... See if you can spot it... clue attached... Great piece of kit and I love the additional screen addon.

    bmv 702

    Very nice bank... we are all very envious... I would set bulk to the highest setting 58.4 and float to 54.4 and then each axpert to charge @ 20A (- I think highest @25A) so 120A to 125A max (both AC and PV). I think we all agree hat 10% charge rate of max capacity, so 128.8A for your bank. That bank needs serious amps to get it to a full charge! Obviously check water levels regularly, I would expect to see a nice bubbling of the electrolyte Check the cable spec... can it handle 120A (they look ok...) @Chris Hobson what do you think! Regards Mark

    LiFePo4 Cells 38120

    3.2V * 16 cells = 51.2 V @ 10ah So 300ah = 480 cells @ 330 = R158 400 without the bms, cables, fuses etc. Are my calcuations correct? Pylontech's for me I guess 6x 14000 = R84000...
  9. Even having water can be an issue... we in Grahamstown found out the hard way last week... http://www.grocotts.co.za/2018/05/25/makana-failed-us-outcry-over-water-risk/ So having backup water isn't a choice I think its a requirement. Even if just to allow you to treat muni water yourself!

    AussieView Manual.txt Thanks guys... very nice functionality!! You will like this @Chris Hobson
  11. The other argument against trackers (given the cheap prices of panels) is to just have more panels in 2 strings facing sunrise and sunset (or NE and NW).
  12. NERSA may be backtracking on this... http://www.nersa.org.za/Admin/Document/Editor/file/News and Publications/Media Releases Statements/Media Statement - Consultation Paper on Small-Scale Embedded Generation.pdf Seems they will be reissuing the a new amended SSEG. Search for @chrisyelland on twitter. This may be excellent news!

    BMV702 battery monitor

    Does the voltage recover after the hair dryer, etc without running the gennie?... I would trust the BMV and see how things go... 48.8V and 81% maybe the best you will do with old batteries (per @plonkster previous post).

    Pylontech US2000B Plus

    When I have the money this is the way I'll go... Chris and I speak regularly but sadly we see each other seldom... He is also keen on the PT's and I like your setup. I do almost the same with the Infini 3+ but just don't have the batteries yet. Thanks for the feedback! Cheers Mark

    Pylontech US2000B Plus

    Hi again @SolarNoob Looks like the PylonTech's are treating you well. Are you off grid and if not how much do you use of the Grid to top up and when. I would love to go the PylonTech route but have more load than I think 4x PT's will handle... but then I compare myself on PVO I see you seem to handle fine PS: My performance is low as I don't use my batteries at all... just float them off PV during the day... I have what @Chris Hobson and others call a "draadkar or el cheapo" set of 12V 100ah Excis ... Regards Mark
