14 Gauge Wire Resistance, Foot - Ideas2014 there is no reason you can't have extra then 10 feet of wire among batteries and inverters , im strolling 24 kw 3 radians 8kw nearly forty toes from the batteries, yes i've multiple big wires ie eight 2/zero wires its all a mater of voltage loss ,you could measure between the inverter in and battery out with the aid of adding a cord in your voltmeter to extend it . Below full load you don't need more then a few volts loss or your loosing efficiency.

Voltage drop in cables is a nicely understood engineering calculation . Understanding the cable length appearance up in a cord chart the resistance consistent with foot , instances that with the aid of the period and you've got a total resistance ,when you have two equal sized wires divide the resistance in 1/2 , next calculate your modern-day draw , 30 kw with 48 volts is 30,000 /forty eight = 625 amps, at 625 amps to lose best 1volt you will need a resistance decrease then .0015 ohms a meter of four/zero is .00016 ohms 2/zero is .0002 and 1/0 is .0003 ohms in keeping with meter . A 10 meter run at 625 amps would want a single 2/0 wire at .002 ohms. Now 1 volt is a truthful loss you said it changed into for occasional 1 hr use in an effort to have a loss of 650 watts/hr within the cord would be suitable, in a in use all of the time grid feed like i've at 24 kw i wanted less loss so i geared toward a lower voltage loss of .1 volts . I might advocate runs of 4/0 or bigger twine will let you run for longer periods if wanted with out to a lot cord loss, the alternative place to recall is how low a voltage your inverters can take , look up the spec if 48 volts is it, then the 1 volt your loosing may additionally restriction your decrease battery reduce of set point. This isn't always normal solar engineering but a unique case.

Thanks michael. The guide says "ac wiring need to be no less than #10 awg gauge copper cord and be authorized for residential wiring according to nec(thhn for instance)." So that offers me a start but i suspect there may be a advice/calculation based on the gap or does ac no longer loose electricity like dc?.
