Re: [RE-wrenches] Soldering electrical conductors

[Todd Cory]

In the old days I soldered all the crimp connections that went into the module J-boxes, but now that j-boxes are a thing of that past, so is the soldering. In those days systems were always 12 volt, so resistance in electrical connections was a bigger deal. Todd North Texas Renewable Energy Inc wrote: Wrenches Over the years I have heard almost nothing about soldering of electrical connections in PV circuits, AC or DC. The only reference I recall is from the recommendation that one should crimp AND solder larger compression fittings to assure a permanent connection. There were references to factory made battery cable crimps not holding after installation and during the final "pull-test".
