@MikeD your ears must have been burning today as expletives came out of my mouth lol, well I finally got round to extending the inverter cable replacing the 70mm2 for 95mm2 it wasn’t as straight forward as I was thinking.
I had two issues, the lug hole at the inverter had to be tapered front and back to allow the lug enough room that it doesn’t have to go in square and the lug just bumps on the thread ribs.
Got that sorted and thought it was smooth sailing good just to connect it to the Lynx distributor my Lynx distributors are the 8mm version, the lugs for the 95mm2 cable doesn’t sit under the mega fuse the lug was to tall so shaved it down just enough it clears the the mega fuses black housing.
Total length of the cable is 3.40meters round trip so well over spec now, which is the way I like it. Thanks for the advice
As we say in Fiji, Wananavu (wonderful).
Yes, I agree that the holes in lugs are not designed to let the cable / lug go on at an angle (in the vertical plane). For this reason, if the situation is tight, I will often use a slightly oversized lug - ie 10mm hole for 8mm bolt. However, your solution is just as good, and necessary when you have already crimped the lug. I like Victron’s approach on the smaller MP2’s where the case cable entry is open on one side to allow the cable lug to go on the bolt square, then worked into the final position. Hopefully this mod will be applied to all inverters.
I have the same issue with my 5KVA and 70mm². The hole is just to narrow to allow the lug to go over the thread.
Is drilling out the hole voiding warranty?
also if i would go for an 10mm hole for the 8mm bold is this safe?
I want to mod the invertor so the whole is like the new 4K5. However as they are new warranty is still important
Hi yes that would invalidate your warranty as the product would be damage other than its intended use design.
When I had my Multiplus 5kVA I managed to get 120mm2 cable on the multi through the grommets. Would say get electrical cable lube put the cables through the grommets then crimp the lugs ie with the cables through the hole so a two person job someone to hold the cable, locate it on the bolt and just put the nut on so it doesn’t jump off. Then lube cable and the whole and support the lug to stop as much force going to the bolt push the grommets all the way home then tighten the bolts they will pinch the back of the grommets this makes it really hard to do it when the lugs are tightened before hope that helps
I just heard back from the Victron distributor here, and they stated there is no issue regarding warranty to drill out the whole, or cut them out like the new 4K5 variants as long as you make sure no metal shavings enter the inverter.
i got it confirmed on email from both the company I purchased my unit from, as well as their supplier. (As their supplier will handle warranties if needed)
So hope i will never need the warranty but good to know it is allowed. Will try and make the cuts this week and post the end result.
