I was planning on tying into the Magnetex 6300's DC distribution which appears is lighter than #4 in and out to where it connects to 1/0 cables to the batteries.
So to achieve a maximum of 75 amps a #4 pos+ cable wound need to be run from the converter/charger to the battery banks 1/0 cable or directly the battery bank?
Either way, appears it would require approx. 8 to 10 feet of #4 wire.
My experience with wiring vehicles for batteries is the neg- ground wire usually doesn't require to be the same gauge as the pos+. While wiring my Jeep for a second battery I used a smaller gauge neg- cable and a frame ground.
Some high amp devices such as inverters, winches, etc. it benefits to use the same aught for pos+ and neg- ground.
I have a couple of inverters in storage I haven't really used in the past. One is a Trip-Lite PV2000FC 2000/4000 watt that has 2/0 cables. Some inverters and combo inverter/converters it's recommended to use 4/0 pos+/neg- cables. Trip-lite recommmends to use 2/0 or higher for the PV200FC.
2000W PowerVerter Plus Industrial-Strength Inverter with 2 OutletsThe PV2000FC uses a PWM sine wave which I've gathered is a step above a modified sine wave but not as good as true sine wave. Considered a mid-level waveform by most, desirable for all but the most sensitive of critical of computing applications.
I also picked up a used Xantrex 1750 Plus which is probably good for up to to around 1200 watts.
Both are not true sign wave but should be good enough for my current needs.
However for better efficiency with the entire installation battery bank, converter, geny, etc. a true sign wave inverter is a better choice as it effects battery charging when using a geny.
The problem here is not all inverters are designed for off-grid systems using a geny . Some inverters even though true sign wave can make a battery charging system to have lower efficiency similar to using a modified sign wave inverter.
So when looking for an inverter to use with an off-grid system you may want to look for one that's been certified for off-grid as some are only certified for a grid connection only.
