Emergency Stop Signal & PV Rapid Shutdown Signal
Pins 11(B) and 12 (B) use an ordinarily open & latching switch to connect the two emergency stop pins that cut off the
RSD power supply when triggered, thus stopping the inverter AC output.
Pins 15 and 16 provide the 12V / 100mA signal power lost when the Sol-Ark shuts down using the front button.
Rapid Shutdown: TIGO TS4-A-O | TIGO TS4-A-F | TIGO TS4-O | TIGO TS4-O-DUO | APsmart RSD S-PLC / RSD-D
PARALLEL SYSTEMS: Emergency Stop should be connected to the Master with address 01 and will initiate emergency
stop for all paralleled systems from the one button

connection terminals
• The Built-in 12V power supply in the user area of the Sol-Ark (Pins 15 and 16) is rated for
100mA (1.2W)
• Transmitter fits inside the user area of the Sol-Ark 15K but can cause interference
(sometimes requires placing it outside of the user area)
• TIGO Optimizers are compatible with the Sol-Ark 15K (Do not use the built in 12V Power
supply in the Sol-Ark user area to Power the Tigo Optimizer TX transmitter)
If you are unsure whether or not the transmitter power supply is compatible with pins 15 & 16 of the inverter, contact the RSD manfucaturer
