Ok. Not size for the 120A DC output listed?Consult the manual and/or size for the 182.2A DC input listed.

I see.DC output is for charging the battery.
DC input is for drawing from the battery to provide inverter power.
If you size only for charging, you limit your inverter output by 33%.
I see.
Is it correct that 4awg (25mm2) 7feet wire can handle 150-200A?
And together with 4awg wire I can use a 180A circuit breaker?
Ok thank you.Wire ratings are primarily influenced by temperature - the rating of the insulation, ambient temperature and if it's in any kind of conduit.
These UL battery cable ratings are a good place to start. Not endorsing this site as a wire source, but it's a good reference:

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, thanks.If they're not in the engine compartment (where it's hot), 210A for 2awg is do-able.
The other consideration is wire length. Longer wire has more resistance, and may be insufficient due to voltage drop:
Voltage Drop Calculator
This free voltage drop calculator estimates the voltage drop of an electrical circuit based on the wire size, distance, and anticipated load current.www.calculator.net
This indicates that 48V, 182.2A, 2awg conductors of 10 feet each will results in a voltage drop of 1.19% - should be fine.
Sorry, 1.25X and round up to the next available size. You'd be looking for 225 or 250.
Ok, thanks.
Why should breaker be 1.25 X wire rating?
Won't that be danger for the wire?If you run fuses/breakers at their rated current, they will eventually trip. 1.25X prevents nuisance trips.
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
