Are you sure RSD is required on a non habitable building, historically its
not required. Now that being said we use fire raptor with the best results,
yes it takes an extra conduite and might require a button and power supply

I also recently used the Tigo with Sol-Ark to provide the 12V signal with
good success. The Tigo transmitter can also (barely) fit inside the Sol-Ark
wiring compartment, so you do not need the whole Tigo enclosure for it.
Cheers,
Dave

Hi William.
We have had good luck with the AP Smart Rapid shutdown system. It is
similar to the Tigo in that it sends a "heartbeat" signal to the units up
behind each solar panel over the power wires. I haven't tried the Tigos yet
but would be open to it if the opportunity presented itself. The t
William,
We did one this year, offgrid, Outback Radian with Simpliphi batteries.
Used the outback rapid shutdown option which is probably similar to the
fire raptor system.
Cheers!,

Hi William,
We have a half dozen plus off grid systems using SolArk inverters and
TIGO optimizers. They work well and the TIGO's, from my experience,
have been really reliable. The necessary 12 volt signal can come
directly from the relay in the SolArk inverter.

Hi William,
I have had good luck with the Tigo TS4-AF. Although it does require a 12VDC
power supply for it's RSD transmitter, Outback, Sol Ark and Schnieder have
a straight forward integration not requiring dependency of AC output from
inverter.
Best,
Chris

Friends:
It is quite rare for us to install off-grid systems on roof-tops. We have
one coming up with about 20kW on a large barn roof. This will be our first
off-grid with a module-level rapid shutdown requirement. I see no
exemptions from RSS for off-grid systems in the code. I have looked
26 matches
