Thank you for your question! Our list of Tigo Enhanced Inverters with internal RSS Transmitters is found here: 30K-3P-208V-N Currently, no Sol-Ark product has a factory installed Tigo RSS Transmitter for rapid shutdown applications. You will need to purchase an external RSS Transmitter Kit from your local supplier. This kit contains the power supply and an outdoor rated enclosure. Note, the Sol-Ark internal 12V DC power pins are not compatible with the RSS Transmitter.
I've got a tigo transmitter and core sitting in my warehouse. It might be an older version, but it doesn't have any indication of black or white markings. If I use it would I be good to just install the core either way?
The DC power supply requires a 120V input (line and neutral) that typically goes directly to a breaker on the main panel. Since this device is used for rapid shutdown and will turn off your array if it loses power, we do not recommend plugging the device into a receptacle in your home. If someone inadvertently disconnects it you will lose array production since the TS4s will go into rapid shutdown.
When designing the RSS transmitters, where should we achieve the source of the main power supply unit that converts the a/c to dc voltage for the transmitter itself? Meaning do you install the Transmitter kit via power supplied from the Solar system, or the utility system?
Great question! The RSS Transmitter must be fed by an external 12V/1A power supply fed by a breaker on your AC panel to ensure proper rapid shutdown operation. Please follow the instructions in this video for a safe, Code compliant, and worry free system.
@@Tigo_Flex_MLPE stupid noob question here but my (probably flawed) understanding is that the RS devices at the module level initiate rapid shutdown when the signal from this device is lost, correct? Wouldn't a power failure from the utility then initiate a rapid shutdown of my panels, and subsequently kill my solar array? That seems to be counter to what I'd want in a situation like that, where I'd be depending on my panels to act as a backup? I'm sure I'm missing something, just trying to understand how it all works.
Our documentation states to use the negative conductors to ensure consistency amongst installations, but the positive conductors may be used if your question pertains to an existing installation.
It depends on how many strings each inverter has. Since the RSS Core can accommodate 10 strings, as long as both inverters have 5 strings max, then a single transmitter may be used.
Great question! For a single transmitter and Core, the total round trip distance of the DC lines must be less than 300 meters. If you use the dual Core Transmitter then this distance is extended to 500 meters. The Tigo Academy TS4 course covers this important design consideration along with other criteria to ensure a safe and lost lasting system. www.tigoenergy.com/tigo-academy

Does a Sol-Ark 30K-3P-208V-N inverter incorporate the TIGO Transmitter and Power Supply?

Great question! We recommend swapping that older version with the newer Core that has a black and white side so you can tell the proper orientation.
I’m confused with the 120volt power supply to a 15 amp breaker? What does that mean? Can I not make plug or use a plug for this part?

Hello, is it possible to place the transmitter coils on the positive (red) wire?
Our documentation states to use the negative conductors to ensure consistency amongst installations, but the positive conductors may be used if your question pertains to an existing installation.
If I'm using two inverters in split phase then do I need 2 rss transmitters?
It depends on how many strings each inverter has. Since the RSS Core can accommodate 10 strings, as long as both inverters have 5 strings max, then a single transmitter may be used.
@@Tigo_Flex_MLPE Thanks for the reply. It will be 2 strings each inverter for a total of 4 so I will be able to use 1 transmitter. 👍
Is there a specific distance from solar to transmitter, for it to work properly
Great question! For a single transmitter and Core, the total round trip distance of the DC lines must be less than 300 meters. If you use the dual Core Transmitter then this distance is extended to 500 meters.
