Won't that be danger for the wire? Can I use a 16A 1000V TOMZN breaker between my panels and Inverter as a on/off switch? I have 6S 230w panels. 230x6=1380w Vmp=30v so 1380/(30x6) = 1380/180=7.66A

Ok, thanks. Why should breaker be 1.25 X wire rating?

Ok thank you. So according to the UL battery cable ratings I can use 2awg cable for 178A? Is this correct? Or should I go up to 1awg rated for 208A? Would it be feasible with a 200A breaker og should it be exact 222,5A with a 2awg wire? How exact should the numbers be?

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?

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?

Ok. Not size for the 120A DC output listed?

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:

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?

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?

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?

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

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.

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...

I have 6 230w panels with following specs: Voc: 36.9V Isc: 8.31A Vmp: 30.2V Imp: 7.62A What is the best panel configuration for the MPP MAX 11KW?

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...
