Re: [RE-wrenches] Building strings of modules with variable voltages?

Wrenches One thing to consider is that a good charge controller will cost more then a few modules so in most cases now with the current pricing is to remove and replace with new, I would like to keep the old ones in play with what ever is controlling them but build the new array, stack them up with

Re: [RE-wrenches] Buried Conductors

Hi Peter, For your #2, see 310.15(A)(2) exception. Where you have two different ampacities, you can use the higher one as long as the distance of the lower ampacity is less than 10' or 10% of total conductor length (whichever is less). So for 50' of conductor, as long as the above ground conductor
