Minn Kota, Draw Chart, Mersn.Proforum.Co - The comment on soldering battery cable makes me recoil. Soldering a crimped connection that isn't properly crimped increases resistance at the lug a good way to cause the lug to amplify, operating free, and in case you are not lucky, molten solder all around the region. And no you cannot resolder it reliably. The simplest satifactory connection is a crimp, of the correct size, completed with the proper tooling. I select the open ended kind lugs, tin plated, accomplished with hydraulic crimping tools. I flex the connection after making the relationship, looking for any movement of the strands within the lug. After it passes this take a look at, i coat the whole lug except for wherein it connects electrically with varnish. Please be aware that shrink tubing that isn't adhesive coated is not water resistant! It definitely makes the relationship much less dependable as it will cause water to be trapped within the connection vicinity. Fundamental chemistry comes into play,two distinctive metals, a touch electrolyte? The only question is whether you built a great battery or a horrific one. The result is the same, a bad connection. I spend may additionally a year keeping wiring in electroplating factories where high amp dc is the norm.
Voltage drop in cables is a nicely understood engineering calculation . Understanding the cable length appearance up in a cord chart the resistance in keeping with foot , instances that by the length and you've a total resistance ,if you have two same sized wires divide the resistance in half of , subsequent calculate your cutting-edge draw , 30 kw with 48 volts is 30,000 /forty eight = 625 amps, at 625 amps to lose handiest 1volt you would want a resistance lower then .0015 ohms a meter of four/0 is .00016 ohms 2/0 is .0002 and 1/zero is .0003 ohms in keeping with meter . A ten meter run at 625 amps could want a unmarried 2/zero twine at .002 ohms. Now 1 volt is a fair loss you said it turned into for occasional 1 hr use so that you can have a lack of 650 watts/hr in the wire would be proper, in a in use all of the time grid feed like i've at 24 kw i wanted less loss so i aimed toward a lower voltage loss of .1 volts . I would recommend two runs of four/zero or bigger wire will allow you to run for longer periods if wanted without to tons cord loss, the opposite vicinity to bear in mind is how low a voltage your inverters can take , appearance up the spec if forty eight volts is it, then the 1 volt your loosing can also restrict your decrease battery reduce of set factor. This is not normal sun engineering however a special case.
