    Sorry, I did not think to explain the photos: The photos are of the fuse removed from the system, It shows the components and order of mounting. When it was attached and in use it was FULLY tightened, and not left finger tight as in the photos. kind regards Steve.

    Hello Sunshine_eggo, could I just check something else with you please? This is my thinking for cabling purposes: With my 2 string 4 parallel array, each string will create 2 x 38.12v ( 76 v ) and 1 x 10.2a. I am intending to use the: ECO-WORTHY 6 String PV Combiner Box & 63A Circuit Breakers (...

    Thanks for input, no I have not tried either, will do. I'll learn how to do the v drop test, and complete. thanks.

    Thank you for your advice, I don't think after speaking to you that i want to put another variable in the system that might fail. and it sounds as though the net benefit is negligible at best. thanks.

    Thank you for your reply, really appreciated.

    Hello Sunshine_eggo, Thank you for taking the time to read and comment, it is appreciated, your comments are well received. I have a E/W array, half on east side, other on west side. This is why I am over panelling, thanks for your observations. Concerning fuse size, here is the data on the...

  • Post in thread: WHY THE HEAT ?

    i have observed the heat starts at the fuse lugs, and then spreads along the cables, until the who cable heats. the last place to heat seems to be the bat terminal. I'll try bypassing the fuse and bolting the lugs together... thanks for you continued thoughts.

    Hello, ( Heads up, I'm a newbie) I am installing a solar array: 3s2p , 3 series 2 parallel 330w each panel 10.2A each panel VOC 39.12v each panel. Each series of 3 panels combined output is: 117v and 10.2A ( with a total array output therefore of: 117v and 20.4A, 1980W) I have the Victron...

    Thanks very much, I will proceed........ kind regards Steve.

    Thanks for the chart, its helpful. I'm a little confused with the wire gauge: The Inverter states its spec as 12v 1200 watts continuous power , it does not state its amps. however If my calculations are right the amps value at 1200 watts is 100Amp. The Inverter states in the user manual the...

    Hello, I would be really grateful for experienced persons thoughts / input as I'm trying to avoid a mistake.... I have a 2S4P system that I am installing. 8 identical Panels, each panel: 330W, 32.6V (VMP), 10.2A (IMP) 10.9 (ISC) My array is East / West, as a result I am over-panelling. My...

    Cable is good, (no heat when connected directly without fuse).

    Could you explain what the 150v comes from please?

    Thank you very much. steve.
  • Post in thread: Blocking Diode Question please:

    thanks for your responses so far... but both are not relevant to posted question. Question remains unanswered..
  • Post in thread: Blocking Diode Question please:

    I can buy off the shelf, but they do not meet spec. The panels only contain BYPASS diodes for different purpose I believe, not relevant to question, thanks anyway
  • Post in thread: Blocking Diode Question please:

    off the shelf diodes do not meet the min requirement as described, thanks anyway

    QUESTION REMAINS.... THANKS
  • Post in thread: IS THIS WHAT I SHOULD EXPECT ?

    Hello, I've just mounted my solar panels and I'd very much appreciate someone to spend a couple of minutes to check if my results are to be expected..... Here's the spec: Solar self build Generator Spec: 300Ah LifeP04 battery, max continuous charge rate 150A < 150v/70-Tr Victron SmartSolar...

    sorry, didn't mean to come across rude, apologies.. problem a little frustration coming out ( sorry ) I would not have even thought of them until I watched one of Wills videos, explaining why you should use them on a east / west roof. I give way to your testing experience, and if as you say...
  • Post in thread: Is it looking ok ?

    Thanks for your answer, If I've understood what you have said, in summary: 1: Although the array can generate a theoretical 2,640w, the MPPT will throttle that to a max of 1015w, which is within the 1080W limit of the combiner box ( so it's what is flowing through the combiner box, not what...

    Thank you, will do. I'll let you know tomorrow. Steve.
  • Post in thread: WHY THE HEAT ?

    Hi TorC Here are the results for the following points you suggested I do, Your observations and thoughts would be very welcome: Big picture: A) I'm not sure if it "normal" to generate this heat under these conditions? B) understanding heat is wasted power, when I remove the fuse and wire direct...

    Thank you LakeHouse, your explanation is helpful. Steve
  • Post in thread: Blocking Diode Question please:

    That's helpful to know, thanks. seems a consensus they have minimal impact at best. So I'm now leaning towards not include them. Can I ask your opinion ( on the comments ) made by another purchaser on Amazon re MC4 30A 1000V blocking diodes. "..... do not contain a Schottky blocking diode...

    Hello, I am about to mount a further 2 panels to my small emergency system, and I would very much appreciate if an experienced person here ( not a newbie like me- thanks) would take a quick look and comment if it's wrong! ( or right ? :) ) Please take a look at my numbers / panel configuration...
