Re: [RE-wrenches] combiner bus bar for Sunny Tower DC input?

Are you sure you need to split them? IIR, there are only a pair of conductors going from each SB into the tower. They must be combined on the SMA side of the touch-safe fuse holders in some way. We opted to run all our source circuits from array through 6 external discos then into the ST

Re: [RE-wrenches] array commissioning

We recently began using the PVA-600 Solmetric with its wireless options. I have found it to be a real timesaver for commercial commissioning. Testing can be done from the rooftop, both V I without making a run to the inverter(s) and waiting for generation (to measure each string's Imp). Running
