Question 3

Why does Victron forbid the use of closed conduit for high current DC cabling

Accepted Answer

High-current DC cabling is not generally advised to be placed in a  closed conduit because it diminishes the heat dissipation capability of  the wire, which negatively impacts the ampacity of the wire.

For most of the 120v Quattro line, 4 DC  cables will be used (2x positive + 2x negative) so, for instance, on the  12/5kVA that would be (4) 4/0 cables bundled together, and where a  single 4/0 cable has a maximum continuous ampacity of 445A (assuming  high-quality UL1426 marine wire), that same cable when bundled with 3  other cables now only has a maximum continuous ampacity of 267A.

That too is assuming "typical" ambient  temperatures, whereas the same setup of (4) 4/0 cables inside, say, an  engine room with high ambient temperatures, each cable would only have a  maximum continuous ampacity of 226A.

Obviously this will make proper fusing very difficult, since where you could fuse  a wire at 400A now you have to fuse it at 200 or 220A, in which case  you would likely be quite routinely blowing fuses. So although Victron's  admonishment against installing the wires in closed conduit  may be an aesthetic nuisance, A. a raceway would be fine, and B. I'd  personally much rather an installation be slightly less aesthetically  pleasing than have to deal with either blowing fuses all the time or  risking melted wires and potential fire.

Question 4

RMA

Accepted Answer

Many problems can be resolved with minor system modifications.         Since we are unfamiliar with your system, please provide the         following information:

1, A description of the fault, and under what conditions the         fault occurs.

2. The steps you’ve taken to troubleshoot the problem, and the         results of your tests. The voltages at the input and output         connections of the controller when the sun is up are important.

3. The significant components in your system, for example the         batteries, breakers, and especially the solar panel wattage and         Voc specifications, and whether multiple panels are parallel or         series connected.

4. A photo of the system as a whole, and also connections at the         controller, the breakers, and the battery. Since we can’t view         your system directly, photos are extremely helpful in helping to         diagnose the problem, and speed up the process.

5. If your system was professionally installed, the contact info         for the shop or installer.

Once we have that information, we'll take a look at the         installation and see if we can offer any additional         troubleshooting steps to take or, worst-case, start the RMA         process so that you can send the unit in to us for testing, and         repair or replacement if necessary!
