    New multi plus II install but main redpower wires getting too hot.

    Thanks, that’s kind of what I was doing, but my temperature on the 4/0 is -50 C to +105 C. = 221F isn’t on the scale, it goes up to 194F so I wasn’t sure if I was doing it right. I’m all copper so it’s on the left side of the chart, I’m guessing use the 194F box because that’s as high as the...

    New multi plus II install but main redpower wires getting too hot.

    I ordered a DC amp clamp, as well as a 350A and 400A T-fuse and holder and a new switch. How can I use this DC max current number I get with the chart to determine if there is an issue? I don’t quite understand the chart, perhaps the numbers I get with the clamp meter will help. I’ve been...

    New multi plus II install but main redpower wires getting too hot.

    That’s where I got my motivation to install this 3000 watt Victron system. He made it look so easy. I planned my system after his, I drew it up 2 years ago when he had the first inverter, the yellow one, but i wasn’t ready yet. Once the new Victron multi plus came out I decided to dive in, also...

    New multi plus II install but main redpower wires getting too hot.

    I don’t have room for a second inverter, I barely fit five batteries over the generator. I think I could do another 5 batteries in a different spot, but another inverter would be hard. the batteries are $200 off today (prime day), I was thinking about doing the other 5, but if I can’t make this...

    New multi plus II install but main redpower wires getting too hot.

    I was probing everything, I tried at the holders bolt lugs, then at the cables crimped on lugs, I didn’t push into the wire if that’s what you meant. I checked from the right (out) side of the shut off switch to the input cable lug of the fuse holder, that’s where I got the largest 0.010 Once. I...

    New multi plus II install but main redpower wires getting too hot.

    I’m going to order one, what size do you run?. That fuse is blue sea. Apparently the T-fuses where hard to get for a while, so theses where the next option. looks like they are available now. this is a Victron distribution box/buss bar, it should be good. I’ve been tracing the heat source, it...

    New multi plus II install but main redpower wires getting too hot.

    I put this jumper wire on and eliminated the fuse and switch and the wires didn’t go over 110 degrees, felt more normal. I put the switch back on, this time the right way and it’s heating back up. Already past 140, maybe this switch is bad. Any ideas or help would be appreciated, thanks.

    New multi plus II install but main redpower wires getting too hot.

    The right side of the short wire at the shut off switch is 10 degrees hotter then the left side of the short wire and the fuse holder and other stuff. That left side of the switch seems to be the hottest as the temperature climbs. My temp tool isn’t reading the right side of the switch as well...

    New multi plus II install but main redpower wires getting too hot.

    I’m not sure if I did the voltage drop test right, but the shut off switch was up to 0.060, the highest of all. The fuse was up to 0.030 alone, the short wire was .002. All together was hitting 0.10. Is that allot? The littler fuse on the distributor for the wire going to the inverter was 0.030...

    New multi plus II install but main redpower wires getting too hot.

    Hello, new to the forum. I just installed a multiplus II 12 volt into a RV With 5 battle born batteries. Everything went pretty good, but the short 4/0 wire between the fuse block and shutoff switch of the hot side is getting really hot when i run the ac off the batteries (AC and frig pulling...
