All with lugs to crimp on, lug sizes for the above for use on for 10mm battery studs. I have seen solar flex (twin wire - black and red in flex) on the Rubicon catalogue. Looks like it would be great when pulling a string, etc. That would be nice in the various sizes. TwinSolar PV1-F is there product name.

October 20, 20169 yr @Energy Had a look at the store well done on a job done well!!! Keep it going Jay - hope to have some spare cash soon to support!
October 20, 20169 yr Author Thanks all! We just put the essentials up so long. Every week we will add more items. Next up solar flex cable and more trojan. :] Thanks all
October 21, 20169 yr Jason Are those busbars on the store suitable to connect battery strings together in a battery bank? I have 4 strings so would need a busbar for positive and negative respectively. Which one would you recommend? Cobus
October 21, 20169 yr Hi Jay, Some things I struggled to get hold of when I did my installation (and I have not spotted it in the store yet ) are: Panel mounting hardware DC disconnects / breakers for PV (high voltage) and battery (high current low voltage) PV Fuse holders and fuses DIN / DB mount battery fuse holders and fuses MC4 connectors / splitters / branch connectors / PV combiner boxes Then things like crimp-on lugs for the battery cables and crimping tools for those as well as heat-shrink tubing (red and black) to finish off the ends of the crimped battery cables. Thanks

Once when I was testing batteries, I found heat-shrink problematic when a battery had a internal short and the UPS kept on doing it's level best to power a 250w load. Heat-shrink melted.

I would think that cable of yours would have gotten equally hot without the thin layer of heatshrink. With vented batteries I do think it presents a bit of extra risk: that horrible paste that collects on everything gets in there and then it has a nice little pocket from which it launches it's corrosive attacks.

Heat-shrink gives a professional look to a cable joint and in this case to the lug crimped onto the cable and won't loosen and get all sticky and messy in time as when insulation tape is used. Heat-shrink will not mask a problem in the connection, but it looks a damn side more professional than insulation tape. Heat-shrink melted. Other forms of insulation would also have melted.

October 25, 20169 yr Author Hi GUYS :> Just got off the line direct with HELUKABEL, We will put 4mm all the way up to 12mm solar flex cable, lugs and MC4s on the store :> I use helu personally the 6mm its fantastic, flexible and solid quality. Should be up in the next 24Hours :> Sincerely Jason

I have 4 strings so would need a busbar for positive and negative respectively. Which one would you recommend? Cobus Hi Jason, have not received a reply from you on the question above. Would this busbar work for connecting my 4 battery strings together? (Positives together and negatives together.) It is a 48V bank, my inverter is set to charge and discharge at max 20A so the 150A rating of the busbar should be ok? Cobus
October 25, 20169 yr Author Dear Cobus. I am not an expert unfortunate on this topic, I am sure the other members will be happy to help. Do let me know if you get sorted. If no luck I can get you the answer direct from Blue Sea. Do let know Im always here. Sincerely Jason
October 25, 20169 yr Author Looking at it. In my opinion it should be just fine. Maximum Voltage: 300V AC/48V DC 250A. Sincerely Jason
October 25, 20169 yr Author @superdiy @plonkster @TinkerBoy @The Terrible Triplett @Chris Hobson Your Thoughts above? Sincerely Jason
October 25, 20169 yr Yes, it will work. Cobus, the busbar needs to support the current which might flow, not only the 20A charging current, but also the up to 92A which the infini might draw under full load. The basbar in question can handle 250A @ 48V continiously, so it should be perfect.
