Southwire, Ft. 12 Yellow Solid CU THHN Wire - However i should say that the extra i examine your posts, the extra concerned i am which you don't have the working knowledge vital to correctly do this assignment. I think you'll do your self a massive choose by using concerning an experienced, legitimate installer of battery-primarily based electricity systems. If there isn't always one regionally, i endorse a certified electric engineer.
One extra issue. On long distance runs, it'd be much less costly to use the stiffer 1 - zero huge strand copper twine in conduit as opposed to the high strand copper. They make "in line" areas to convert from low strand to high strand 1 -zero wire at the termination points on the battery bank or inverter. Adding a 2nd battery financial institution of even just 2 batteries, on the inverter area, will allow for cleaner begin united states of americaand peaks in masses. Keep in mind to fuse the second one battery bank.
Study parallel conductors and the "25 foot faucet rule" inside the nec. Low voltage, below 50 volts to floor or betwean conductors, desires simplest the right fuzing to shield the twine however you may discover, because of the very huge conductors used, you can need to decrease the fuze size to guard the device. They make "double lugs" for 1-0 wires for connecting to inverters and you can parrallel low voltage wires from batteries smaller than 2-zero so long as the overall duration of each conductor in the parralel run is identical in period and same in size. The inverters inner fuze protects the conductors so long as they're sized smaller than the full load ability of the twine and the conductores are 25 toes in duration or less. On distances over 25 toes, the conductors have to be fuzed at the batteries. 2 - a hundred watt slow blow fuzes would shield the 2 1-0 conductors for inverters wherein your general used load might no longer exceed two hundred amps or 2400 watts at 12 volts 4800 watts at 24 volts. Slow blow fuzes could permit for motor starting and peaks that a few hundreds may additionally experiance as long as this is inside the rated "top" if your inverter. Voltage drop is primarily based on load modern and on low present day inverter masses, many inverters will still run with a voltage drop right down to 11.2 volts for a quick period of time on a 12 volt device. I've located that with the aid of connecting the inverter as close as feasible to the sun panel fee controler enter, the better pv voltage will assist mitigate the voltage drop on load start up for motor leads like air conditioning or fridges durring daylight. I also recomend you use separate inverters for each moter load in any other case muliple masses can triger a simutanious begin whilst the voltage drop trigers the thermostate of the other unit. You only want one inverter for all your led lighting hundreds in your home and small elecronics.
