    Thank you!
  • Post in thread: Wiring for safety - can I overlap cables?

    Thanks. Assuming that no accessories are available, they don't sell that stuff in stores where I am and their electrical safety standards are questionable to say the least, what cable mounts do you suggest I use (ie. materials so that I can find some alternative).
  • Post in thread: Earthing and surge suppression in high risk zone

    Hi All, I have a 3.3kw array split into 3 x 1.1kw series in parallel which then tie into a surge suppressor which is connected to a physical earth pit a few feet away on a 6 gauge copper cable. The live cable runs 120ft to a 50 amp breaker and then to the inverter which is connected to another...
  • Post in thread: Earthing and surge suppression in high risk zone

    Thank you! My next question is how do I wire a split phase spd. I have an ac spd rates for 275v but it has two L inputs. The DC spd is straight forward as it is labelled with plus and minus but the AC one only has 2 Ls. Would I need a special sod for split phase or will the one I have work? Is...

    I'm in Yucatan, Mexico

    Thanks. 48v, sorry. I was told that due to the large distances (with hills) between the solar panels, inverter and house it would be best to have more than one earth pit.

    Thank you, yes. I will do this as soon as possible. Having no internet does complicate things
  • Post in thread: Grounding question - how to connect ECG from panels to Growatt inverter

    Hi, I found this video on another post where Mike Holt explains that you should use one common grounding point for the whole system rather than using multiple rods. In practice, how would you connect the PV EGC to the inverter? I have a Growatt SPF 6000 DVM MVP and there are only two entries...
  • Post in thread: DC breaker wiring - weird diagram

    Hi All, I'm scratching my head trying to figure out how this 20a DC breaker is wired from the diagram on the unit. It's a Suntree SL7-63 rated for 800vdc. I'm a beginner so was expecting the supply to go in at the top and the load to come out from the bottom but this doesn't look that straight...
  • Post in thread: Wiring for safety - can I overlap cables?

    Hi All, I'm a newbie who recently installed a 48v solar setup with 3.3kw array and 6kw inverter. I am finally ready to go ahead with the AC installation in the house but I'm wondering if it's safe to overlap cables like positive, negative and earth. Any recommendations are highly appreciated...

  • Post in thread: DC breaker wiring - weird diagram

    This is great. Thank you so much for clarifying. I don't need 800vcd so will use the quick route ?
  • Post in thread: Wiring for safety - can I overlap cables?

    Hi, thanks. I meant this (see pic) are there any rules on which cable can or can't cross another?
  • Post in thread: Wiring for safety - can I overlap cables?

    Those lines are the PV input. One comes from the 50a breaker and the other from the surge suppressor. Where I live they don't sell nuts to connect 6awg cables so I spliced them. The red is positive the black is negative. Max input is 42 amp and 93 volts. The AC output from the inverter is placed...
  • Post in thread: Need help with reviewing my installation

    Hi All, I've recently setup a residential solar system in a remote off grid location and need help reviewing my final installation plan. I have some of the wiring done but some of the connections are still temporary until I can get a better idea of what I'm doing. I don't trust local...
