Christopher, I can’t be certain, but I suspect that the APSmart units have the same circuitry as the Tigo RSD units. I say that because of the press release below. I suspect that the only difference is the enclosure, but that is merely speculation. Interestingly, I worked for Tigo nearly a

I would like to suggest that interested WRENCHES form their own "subcommittee" so that we can have an somewhat organized approach to this issue.  I do know Fronius has been working on this, and we should seek them out.  I will volunteer to help organize the subcommittee.  I have done similar

I tell my grid friends to buy a Genset. If they can afford a roof mounted solar power system and all of the RSD bloatware, they can easily afford a good genset. A recent project, the county would not approve the offgrid home unless it had power. I was too busy (it was too hot) to get involved

It’s good to see everyone waking up to the dangers of RSD. This last code cycle has been a complete disaster for solar, between RSD and these obscene set back requirements for solar panels on the roof, it really looks like residential solar is under attack by hostile forces, driving up costs

Fronius is also involved in the effort to remove the MLSD requirement. https://solarbuildermag.com/featured/safety-concerns-for-solar-pv-module-level-shutdown-solutions/ In order to remove MLSD, it would require financial backing to get someone on a committee, pay, house and feed them

All of these new code required safety features have a detrimental effect on reliability.  That's not a huge deal with GT, but off grid, this can become a serious safety issue in itself, as the homeowner loses communications, water, heat, and frozen food. There are opponents of solar energy

The Schneider RSD is decent. At least it is useable as a 600vdc disco. The few offgrid homes that were required to use this had the Tigo units on the array panels and wireless comm to the RSD. As soon as the inspector was done, those went to Ebay. I never use a roof but have used a barn for
