    Volatage drop

    Yes great idea. I can even use my thermal imager for this. Also agree, cables will need to change. I was thinking of pulling out the existing and going for 73mm2 welding cable but, as suggested above, it will be easier to run another of the same 53mm2 cables.

    Awesome, will definitely test breaker. Cheers

    Yes, I have the inverter connected as per image on the right.

    Yes have a 200amp circuit breaker very close to the batteries

    Thank you so much for the detail. Most of it is over my head. However based on me not running a reverse charge through the BP, do you seen an issue with the inverter connected on the in/battery side of the BP? thanks again. rob

    Yeah definitely just a pure sign wave inverter. I’m going to bypass it to test the system now regardless. Thanks

    Hmmm, they, as in the retailer here said no issue as long as connected to the battery in side it wouldn’t affect it. But. Now that you say that I scan easily disconnect from the BP and test. Cheers.

    Correct, inverter connected straight to battery side of the BP.

    Ok, I can definitely try that. Does this change at all if the max I will use from the inverter is 2200w?

    Itech world 3000w company here in Australia, likely Chinese made though. They do get pretty good reviews here.

    Hmm I think it may not have much to do with the cable set up then

    Is there a way to test the inverter to see if it is the problem?

    Volatage drop

    Thanks to you and Matt, are you saying that a 3kva inverter will draw 275A? If so I am definitely well below At 200A system supply. Getting nice big gauge lugs to suit the wire was also an issue at the time so I will look at up grading them also. Would I be better swapping to the 70mm2 cable...

    Hi gurus, I have a twin 130AH lithium set up in my car. So 260AH. The batteries are for start up and auxiliary components. The BMS automatically cuts power use to ensure the car is always able to be started. Anyway….I’m running 53mm2 cable 6m from front to rear. Same cable pos and neg, Victron...

    Voltage drop

    I’m running 1/0 AWG cable in my system, I am getting voltage drop at my inverter. obviously need to up the cable size to AWG 2/0. This cable is not available where I am for me to change out the cable. So my question is if I was to run a second smaller cable, 8AWG (which I can get and run fairly...
