Re: [RE-wrenches] Silfab
Hi Howie, We have installed probably 150 jobs with Silfab modules. First their 330W, then their 370 half cell modules and now their 400 watt modules. We have had good experiences with them and there relatively inexpensive for an A tier module. They manufacture them in Washington state and the company is based in Canada. This helps fill our priorities of sourcing products from North America as much as possible. We have had two modules with issues. One being a module that dropped out about mid day, and the second having a partial voltage reading. I troubleshot both and found that Silfab was decent at responding with a warranty credit for replacement through our supplier. I would say that, overall, the value Silfab brings is quite high while also being decently priced.

Re: [RE-wrenches] IQ8 "line noise" issues?
Hi Lars, It is likely that the IQ8 micro's are more subject to line noise then previous models. We've had line noise and comm's issues in the past with IQ 7's as well. A cheap solution that we have had some success with is to put ferrite core snap together chokes around L1 and L2 PV input wiring. You can get these at Radio Shack for about $6-8 a piece. This would be a much cheaper solution then the Enphase filter. You can also try the solid core type, and your installers can just pass the conductors through them as they wire the combiner box. You can also get much less expensive in line filters that are similar to the Enphase filter on Amazon for $20-50 a piece. Good luck and happy solaring.

In both of our recent installs they are not in neighborhoods that have a number of systems, and the issue is not finding too many, but finding very few to none . Enphase has suggested purchasing a Q-LCF-064-1P line filter ($500), and I wanted to see if this is something that is "more common" on the IQ8 that we should plan on as part of our pricing. Any wrenches found cheaper alternatives that work?
