Could be.. i just saw it was shaped the way i needed. Maybe i should look some other type terminals then? Edit: maybe this type better?

Look for flat blade ferrules, you may need to take a picture to your local electrical emporium. Link to comment Share on other sites More sharing options...
Muhendis Posted February 3, 2023 Share Posted February 3, 2023 If I were you I would take the two (or however many) battery cables to a common bus bar and then have a single cable from that to your isolator/MCB. The thought also occurs to me that the cables may be bigger than they need to be. Link to comment Share on other sites More sharing options...

Cables are 35mm2 as requested in Growatt manual. Batteries will be parallel connected between inverter and breaker.

Pink7 Posted February 3, 2023 Author Share Posted February 3, 2023 I found a 50mm2 version of this, Material: Tin Plated Coppe Description: Made from 100% Annealed Copper for Max Current Flow The flat part is 7mm x 2.6mm. I hope that's enough for 100Amp? Pink Link to comment Share on other sites More sharing options...

I also see that its quite a challenge to get 35mm2 cable in to 35mm2 lugs, i might need to return the 35mm2 lugs and get 50mm2 lugs. Pink Update: I wired some thin still tread around the wire to tighten it on 3 different levels and was able to get the wire into the lug, the removed the wires one by one.
