  1. Grid tie without battery backup question

    Yes, I meant that sunnyisland, not sunnyboy. At the scale you mention, a small lithium battery will obviously be more cost effective.
  2. 5kva Axpert MKS model - faulty

    Yes. Yes.
  3. Surge Protection For Solar Panels

    I prefer using Type I + II (Type 1 + 2) surge arrestors. They are far more expensive than the normal Type 2 surge arrestors, but I would rather be safe than sorry.
  4. Don’t send your Bitcoin Cash to Luno

    Agreed! I've sent BTC and ETH to and from Luno many times. Just make sure you got the right address.
  5. Newbie needs advise on stand alone system please

    I have run 235W and 255W panels together, purely cause "that's all there was" for a long time. In parallel, it will default to the lower amperage. In serial, it won't matter much, but the total voltage will be the sum of the panel's voltages. It is not ideal but will work if that is what you have to work with

    You get 10mm2 as well.
  7. Mecer 5kVa settings and monitoring

    I can do the installation, will PM you my contact details.
  8. Ironically they were designed with marine usage in mind.
  9. 5kva Axpert MKS model - faulty

    mustek could also repair it.
  10. Axpert MKS 5kva Power-Cycling in OFF position

    Agreed. Many inverters will still operate, at least to charge the batteries, when the PV and batteries are connected. Switching it off generally only stops AC output. Some inverters though have a battery and PV isolator if you want to disconnect / switch off those as well.
  11. Anyone use Solarus panels before?

    but that it "hot water energy" not electrical energy. My, and I guess most people's needs are a lot more towards electrical energy than hot was energy.
  12. Grid tie without battery backup question

    Ironically, although I want to use a Goodwe, not because @Chris Hobson manage managed to do run it without batteries, but because it's a nice inverter, it's too small for this site. I need to power 7Kw constantly so the SMA would not work in this case either. And to add battery backup to an SMA system is much more expensive, since you need to have a sunnyboy as well, than just adding a battery bank to an Infinisolar. Even Victron are battery driven inverters with MPPT as an option so that wouldn't work here either. Anyway, I just wanted to get my facts straight since my business partner recons it can be done, I think / thought it couldn't
  13. They claim 4 time more production as same size panels. https://www.cbn.co.za/services/power-solutions-energy-efficiency/advanced-solar-technology-of-solarus-applied-to-landmark-vineyard-hotel http://socialstockexchange.com/members/solarus/
  14. Hi, I hope someone has run into this before, since I haven't done anything like this yet. Has anyone used a grid-tie inverter without battery backup, and it still works when eskom fails? i.e. will the inverter still draw power from the PV array, or does it need a reference voltage to work? My gut is that it needs a secondary reference voltage, i.e. the grid or battery bank to work. 2 suppliers also confirmed that it definitely needs a reference voltage of sort to work - on all brands I would have wanted to use, i.e. SMA, Victron, Infinisolar.
  15. Newbie mistakes on first solar install

    I use a small "DC Buck booster" to draw power from the 45V (54V) battery bank and convert it to 12V, works quite well.
