    Solar configuration

    Ok, great. Thank you! Where can I find a reliable wire rating chart? Is this reliable? So wire size for 182,2A is 00awg (67,4mm2) wire?

    Solar configuration

    I see. So for sizing for the 182.2A DC input listed: Is it correct that 4awg (25mm2) 7feet wire can handle 150-200A? And together with 4awg wire I should use a 180A circuit breaker?

    Thank you very much! 😊 How to determine wire size and circuit breaker between inverter and battery? My battery is 48V 270ah (13kwh) Here is the inverter:

    Solar configuration

    Ok. But according to your "1.25X the wire rating" statement I should have a 25A breaker when using a 13awg wire which is good for 20A? This is for protecting the wire?

    Solar configuration

    Ok nice. I've already a 2.5mm (13awg) wire buried from the garage to the battery shed. What about my 63A circuit breaker, is it pointless to use?

    Solar configuration

    Ok, I've bought a 63A breaker, it's maybe too big? Wiresize: is this correct?: I have 6S 230w panels. 230x6=1380w Vmp=30v so 1380/(30x6) = 1380/180=7.66A So I have to use a wire that's good for 7.66A? 1.5mm2 (15awg) wire is good for 15A so it should adequate?

    Solar configuration

    Where is the "max fuse" value on this? Should it be listed here?

    Solar configuration

    Ok, thank you, then I'll go for 6S Ok, no fuse in 6S configuration. Anyway I want a breaker to cut the power if I want to. What size circuit breaker do I need before the inverter? Ok, so strings is the same as parallel.

    Solar configuration

    The same with this inverter? I have a Voltronic Max 8kw. Is it possible to have 3s2p? It's often shading on three of the panels... And what size circuit breaker? I assume I don't have to fuse the panels in 3s2p configuration? I don't understand the manual with the recommended solar panel...

    Ferrule on circuit breaker?

    Yes it has clamp style terminal. How tight should it be? Should it be impossible to take it apart with the bare hands? I tightened it the hardest I could but I can take it apart with the bare hands...

    Using wood/plank/barge as mounting rails for solar panels on the roof.

    Is there any issues with using wood/plank/barge as mounting rails for solar panels on the roof? It's much cheaper but it's almost no one using it. Is there a reason not to use it? I found just one guy on YouTube using it:

    Zero-export inverter, not backfeed to the grid

    So if I connect the grid mains to an offgrid AIO (like MPP MAX 11kw), the inverter doesn't has to be tested according to the standards (Certifications)? The inverter doesn't has to be approved and I don't have to tell the power company about it?

    Zero-export inverter, not backfeed to the grid

    Ok great, so if I use a transfer switch the power company will consider this as "not connected to grid"? Like this? It's called semi-offgrid in this link here. Does this power transfer switch ensure it doesn't feed power back to the grid?

    Zero-export inverter, not backfeed to the grid

    Do you mean even if I connect the mains in to an offgrid AIO, the inverter has to be tested according to one of the two standards (Certifications)? The utility gave me this answer: "As long as there is an off-grid solar system (not connected to the power grid), you do not have to send an...
