Basically the company that want to use me have no interest in elecktrickery and all its regulations etc. They will have all the paperwork, working at heights, MH, COSHH etc and just be subbing the electrickery bits to me, So to my mind I would not need anything other than what I already have.
As far as the connectors are concerned....the Inverters are SunnyBoy and come with the tool-free SunClix connectors. The panels come with MC4s [so far] and need extending down to the inverter isolator. Looking at some crimper prices, it's a joke. FFS how hard can squashing a wire be??? I must have the equivalent of the national Debt of a small Principlaity in crimp tools.
RG58, RG59, RYB, 6-10-16, 16-25-35, bootlace ferrules to 50mm, hydraulic 6mm to 400mm [3 sets] the list goes on and on. and now Solar crimpers as well!!!!! back in the day we used to use a flooring chisel and a big 'ammer... :coat
I'll see what MM can do on tooling.....MM are you there?
